How to make glue

Main components

Food glue differs in that it is created on the basis of natural ingredients that are harmless to the human body. The industrial-made retainer most often includes:

water;
citric or acetic acid as a preservative;
additive E466 - sodium carboxymethyl cellulose, capable of imparting viscosity to the mixture;
potassium sorbate.

The release form can be of two types - liquid or powder. The first one can be used immediately, powder takes time to prepare. Today there are many recipes from which you can make food glue from common products at home. For this you will need:

chicken egg whites;
white or dark chocolate;
lemon acid;
flour;
powdered sugar;
sugar syrup.

The glue is easy to prepare, it sets quickly, easily tolerates temperature extremes. You should not cook the mass in large quantities, since its consumption is economical.

Magic Colors

Magic Colors food glue is a ready-to-use thick mass. The components that make it up are of plant origin. The liquid has good fluidity and density. The adhesion of the components is strong, so glue is often used to connect mastic elements, marzipan figurines.

The mixture is applied to the glued surfaces, which are connected, and after a while their fastening becomes reliable. Food glue comes in handy if small items have been damaged on the cake. The fix is easy with Magic Colors, just one touch with the brush. The composition will help if the culinary specialist is faced with the task of combining rather massive mastic jewelry.

Rainbow edible glue

The food glue of this brand is based on carboxymethyl cellulose. It is made from caustic soda and cellulose. The substance is tasteless and odorless. It is used to thicken and obtain viscosity. Rainbow edible glue is often used by professional pastry chefs to create designer cakes, wedding cakes.

It does not belong to allergenic products, reactions of this type have not been noted. Vegetarians can eat foods using this glue, since there are no components of animal origin in the composition. Rainbow edible glue is manufactured in the UK. You can buy it in plastic containers of 25 or 50 grams.

QFC Essentials Edible Glue

British brand culinary glue has an edible "sugar" composition. It is ideal for making culinary mastic, from which flowers, decorations, and figures are made. Its high adhesive capacity helps to hold heavy dessert decorations. The composition of QFC Essentials sets quickly and is resistant to temperature extremes. Food glue is a colorless, viscous liquid. Packaged in plastic containers of 18 grams.

How to make your own tile adhesive?

For interior work in a house or apartment, where complex mixtures for laying tiles are not required, you can use a solution prepared by yourself. Of the materials you will need:

fresh cement grade not lower than 300 - 1 part;
fine-grained sifted sand - 5 parts;
water - on demand;
plasticizer - 1/25 part.

As a plasticizer, PVA glue, slaked lime, silicate glue or liquid soap are suitable. First, cement and sand are mixed, then the mixture is brought to the desired plastic consistency with water. At the last stage, when all the lumps disappear, add any of the plasticizers.

Beginners should know that a solution prepared from a dry mixture should be used as quickly as possible, but without haste. It is impossible to leave the glue the next day - even if it does not completely harden, its useful properties will be lost.

Possible side effects

There are secrets in the preparation and use of mastic jewelry, the knowledge of which allows you to prevent an unexpected end result:

the powdered sugar used for the manufacture of mastic is prepared carefully, ground very finely, otherwise the layer will break during rolling;
mastic should not be applied to a raw crust (sour cream, impregnation), since it can dissolve when it comes into contact with moisture;
before applying the mastic to the butter cream, the dessert is placed in the refrigerator so that the cream hardens well;
small decor details can be glued by moistening with water or protein with powdered sugar;
if the figures are glued and put in the refrigerator, they can absorb moisture and fall off, so the decor is attached before serving the dessert on the table;
parts made of marshmallows can be painted with food colors;
when the mastic cools, it loses its elasticity, which can be returned by placing the decorative material in a microwave oven or a heated oven;
the remnants of the mastic are stored in the freezer - up to two months or two weeks on the refrigerator shelf;
dried but unused figurines are placed in a box and stored for 1.5 months.

How to get the right taste and consistency

The pastry glue should have a neutral taste and smell so as not to interrupt the main course. Too thick or liquid fixative, composition with lumps will not give a reliable connection, spoil the appearance of the product.

Little things that affect taste and texture:

Sometimes the icing sugar sticks together to form one large lump. Take the time to crush it as small as possible. Otherwise, the mastic will tear when rolling.
Do not apply the confectionery composition to the soaked crust, only to the dry one. The glue can dissolve due to the large amount of sugar.
If you are using buttercream, let it cool well in the refrigerator before applying the mastic.
Decorate the cake shortly before serving, otherwise the figurines will get wet and no longer hold their shape.
If some of the items dry up while decorating the cake, place them in the microwave for a few seconds. This will return them to their previous state.

The mastic can be stored in the freezer for up to two months, and in the refrigerator for no more than two weeks.

What is conductive adhesive and when is it advisable to use it?

In everyday life, there is often a need to connect several parts together without using a drill. And sometimes a high electrical conductivity of the connection is an additional condition. In such cases, a conductive adhesive is used.

It is widely used in the creation of electronic devices for attaching various elements to an integrated circuit. It is also an indispensable element in the automotive industry for securing and sealing wiring.

But if desired, it can be made at home from readily available materials.

How to make glue yourself - the main ways

1. Buy any quick-drying glue or special varnish in the supermarket.
2. Take a simple pencil with a rod hardness of M4 or M2, remove the graphite from it and grind it into fine dust in any convenient way.
3. Without opening the tube lid, carefully unwind the foil from below and align it.
4. Pour graphite dust into a tube with glue through the hole that appears and mix everything thoroughly until a homogeneous mass is formed.
5. Wrap the foil back and press firmly to ensure complete sealing of the interior.

As you can see from the step-by-step instructions, the method is incredibly simple, fast and cheap. In this case, you get a glue that is quite suitable for solving everyday issues. The only drawback is that it will not be possible to use it on painted metal surfaces. This conductive adhesive is suitable for glass, linoleum and other materials.

There is also a more costly and complex way of preparing the material:

In a chemical store we buy silver nitrate or ordinary nitric acid with a capacity of no more than 10 milliliters.
In a pharmacy or clinic, we buy 1% formalin solution and ammonia.
Next, we combine all three substances in equal proportions and observe a violent chemical reaction, as a result of which a silver precipitate is formed.
We isolate the precipitate from the solution by filtration and distilled water.
The resulting precipitate is heated for several minutes at a temperature of 100-150 degrees Celsius to evaporate excess liquid.
Next, you need to add a few drops of ethyl alcohol to the resulting black powder, and then mix the substance with quick-drying glue, in the same way as described in the first preparation method.

This method will require a lot of effort, time and money. But the result will be better. Such a conductive adhesive is already suitable for stubs and other complex electronic elements.

According to its characteristics, it will actually repeat the factory product. Self-made materials are usually resorted to by people who like to do something with their own hands.

For everyone else, it will be easier to buy a professional squad and not worry about its quality.

Properties of conductive adhesive

- dry instantly so that the high pace of the master's work is not lost;
- have sufficient viscosity so as not to spread over the entire processing surface, but to remain in a clearly defined area of responsibility;
- have good adhesion to any material and substance;
- have a high level of electrical resistance;
- comply with environmental safety standards;
- have thermal stability, since soldering is often used on microcircuits, and they also heat up during operation.

Varieties of glue

Another conductive adhesive - "DoneDeal" works on a slightly different principle. The delivery set includes two special syringes, one of which contains the glue itself, and the other contains conductive paste.

During operation, they are mixed, and the paste is applied to the contact, and from above it is already sealed with glue. This significantly increases the conductive properties and ensures reliable fixation of the product. According to many, at the moment this model is the best on the market.

Its only drawback is called quick drying after opening the tube.

It is not worth buying a large package, because the product quickly freezes after opening, and you still have to purchase a new tube for the next repair.

It will no longer work to dilute the dried glue without prejudice to its technical characteristics, so it is better to immediately discard this venture.

Purpose and scope

The scope of application is due to the properties of the adhesive. Since it fixes wood and paper surfaces well, the composition is actively used in construction and furniture production. The environmental friendliness of the substance allows it to be used in the food industry.

Furniture manufacturing

The composition has several advantages:

resistance to high temperatures;
security;
non-toxicity;
water resistance;
improving the structure of the tree.

Construction

During construction work, putties and putties with a substance content are indispensable. Casein paints are used to decorate the facades of concrete, brick and plaster buildings, as well as to obtain a washable interior decoration.

Painting and typography

Casein-based paints are used in painting and printing. So, emulsion casein-oil paint is used for decorative painting on cardboard, canvas, wood, concrete and stone, it is applied to a primed surface.

Chemical industry

Acidic casein is used in the chemical industry as an additive in papermaking. Part of varnishes and paints.The color and cosmetics industry is also a major consumer of casein.

Food industry

As a natural animal protein, casein is highly nutritious. This protein is often found in infant formula and nutritional supplements for athletes.

Production of labels

With the help of casein glue, in a number of industries, labels are glued to glass containers. In such a case, modified starch is usually included in the composition.

Iconography

Since ancient times, paints of animal origin, for example, egg paints, have been used to paint icons. Currently, casein paints are often used, since after drying they are waterproof, but at the same time breathable, that is, they are permeable to gases and moisture.

Additional tips and tricks

When using casein glue, you need to remember some rules:

Before work, you need to prepare the workplace: cover the table and, if necessary, the floor with paper.
It is advisable to protect hands with gloves.
It is better to remove excess glue immediately after application, then it will be more difficult to do it.
The glue is usable within 4-5 hours after dilution, after the loss of properties it is impossible to reanimate it.
To avoid the formation of mold, ammonia is added to the composition.

When choosing glue for repairs, carpentry or handicrafts, it is important to pay attention to the environmental friendliness and availability of the composition. Casein glue, due to its natural origin, is absolutely safe for health. Given the good fixing properties, the composition is practically irreplaceable in the case of working with wood, cardboard, porcelain, fabric, plastic

Given the good fixing properties, the composition is practically irreplaceable in the case of working with wood, cardboard, porcelain, fabric, plastic.

The main components of edible glue

The food fixative is made from edible ingredients. When used in moderation, it does not harm a person in any way.

The main components of the edible glue are:

Water.
The preservative is citric acid.
Food additive E 466 - used as a thickener to give the product a viscous structure. It is usually used in the manufacture of yoghurts, curd products, and cheeses.
Potassium sorbate is a harmless additive E 202. Increases the shelf life of products by inhibiting the growth of mold, fungi and yeast.

Sugar glue is produced in the form of a powder for preparation and a ready-made jelly mixture. The minimum price starts from 50-70 rubles per 100 grams.

Popular brands of confectionery fixative:

Magic Colors. Manufactured in Israel. It has a very secure hold, it is used for gluing massive objects. The grip force allows you to hold even marzipan figures. Suitable for masking defects on the surface of the product. Sold ready-made. It is a thick, viscous substance.
Rainbow edible glue. The choice of professional pastry chefs. It is held together by complex designs, multi-layered desserts. The glue is tasteless and odorless. It can be eaten by allergy sufferers, vegans, as it does not contain animal ingredients. Country of origin - Great Britain.
CMC (food carboxymethyl cellulose). The powder is tasteless and odorless. Stir it in water before use. It is used for the preparation of mastic.
The full name is Essentials Edible Glue. Created on a plant basis. Suitable for making and fixing large, heavy parts.

Albumin glue

Albumin composition is used in joinery production. It is obtained from the blood of a bull, which is preliminarily purified from foreign substances, and then dried using a special technology. It differs from wood glue in good resistance to moisture, an easier preparation method and excellent resistance to stress. This type of glue is used for the production of plywood.Albumin glue with the addition of lime and ammonia is effective for wet gluing wood.

Other types of substances that are used for gluing wooden structures:

Glycerine glue is obtained by adding a small amount of glycerin to the wood glue. Its positive qualities are resistance to heat, due to which it is used in places where temperature extremes often occur.
Chalk glue is made by adding some chalk to the wood glue. Due to the transparency of the substance obtained, it is used for gluing wooden structures of a natural color.
Syndeticone liquid glue is obtained by adding acid (acetic, nitric or hydrochloric) to its composition. Its area of application is bonding paper, leather, wood and porcelain products.

How to carry out the procedure correctly

The process is simple, and the technology consists of a few simple steps. In stages it looks like this:

Collect all the pieces you want to connect. If you are re-gluing a broken cup or vase, then it is worth removing the remnants of the substance from the previous time. To do this, use a knife.
Rinse the parts in warm water using dishwashing detergent or other gel-like substance (shower gel, shampoo, etc.). After that, rinse the shards, set them aside until they dry completely, but do not wipe them, as you can injure yourself on sharp edges or break small corners.
Put all the pieces together like a jigsaw puzzle.
Treat the joints with acetone.
Gently, thinly apply the glue to the bonding areas using a brush or a stick for cleaning the ears.
Leave the first layer to dry.
Apply a second coat and press the bonding parts together (hold for a few seconds). Take a cloth and remove any remaining mixture.
Then connect the glued part with another shard (it is advisable to do this after a while so that the previous parts adhere well).
Fix the product well. This will provide a secure grip.

Now you know how to glue ceramics

Since the work is carried out with glass, it is worth taking precautions, for example, wearing rubber gloves to prevent minor cuts or wounds on the hands.

Following the algorithm described above and having figured out how to glue ceramics, it is not as difficult to repair ceramic or porcelain items as it might seem at first glance.

Remember that restored items are no longer suitable for use in the kitchen. When acidic or salty food is placed in such a container, a caustic substance hazardous to human health is released, contained in the glue and reacting under certain conditions.

Now you know the best way to glue ceramics or porcelain products and how to act in different situations related to the restoration of objects and even plumbing fixtures.

7 Homemade superglue is a versatile master assistant

You can get a glue with the characteristics of a universal one based on carpentry. We take 400 ml of water and dissolve half a glass of sugar, add slaked lime - 30 grams. We heat for an hour, stirring all the time. We get a clear solution, drain it and add 120 grams of wood glue, cut into pieces. We are waiting for the moment of complete swelling and cook, as usual, until a homogeneous substance is obtained.

Popular glue recipe - based on acetone

You can make superglue according to another recipe. A very affordable method that does not require large costs is based on acetone. As a filler, we use pieces of linoleum or plastic. Put in small pieces in a bowl, which can then be tightly closed. Fill the raw materials with a double amount of acetone, seal the dishes tightly and put them in a dark place.We look when everything dissolves, and we use it to combine wood, metal, porcelain and other things.

Advantages and disadvantages

Natural components of casein glue determine its characteristics. Positive characteristics include:

Environmental friendliness. The solution, prepared from pure casein without impurities, does not contain components hazardous to health. Therefore, part of it is used for the manufacture of children's furniture and items for children.
High adhesion to wood. Such material holds different rocks together, its ability to penetrate into the upper fibers makes the adhesion more reliable.
In dry form, casein practically does not react to temperature changes.

The main condition for proper storage is to protect the powder from moisture.

Resistant to moisture after drying.

But the substance has its disadvantages:

Since this material is natural, it is susceptible to mold, pest, and fungal growth. Therefore, glue is not recommended for wet rooms.
After mixing from dry powder, such a solution has a pot life of 4–5 hours. Then it loses its properties. Therefore, you need to work with glue quickly enough.
After drying, casein glue leaves dark marks on the surface.

9 To help a hobby - original ideas for adhesives

If you are fond of origami, paper applique, quilling, then, undoubtedly, you know that the best glue for such activities is based on dextrin. You don't have to go shopping for it. Dextrin is easy to make from starch at home. We take the required amount, put it in a heat-resistant dish and place it in a slightly warmed electrical cabinet. Then we gradually increase the temperature until it reaches 160 °. We maintain this temperature for an hour and a half, during which time the starch will be converted into dextrin.

A popular hobby among women is making flowers from a variety of fabrics. Flowers with petals glued to each other are especially graceful, showy. The simplest glue is three tablespoons of flour and a glass of water. To boil the glue, first dilute the wheat flour with a small amount of cold water, and then gradually pour boiling water into a glass and bring to a boil.

According to the second method, mix thoroughly in a glass of water so that there are no lumps, a tablespoon of wheat flour, starch and sugar and bring to a boil. A good glue for making flowers from fabric is obtained on the basis of a gelatin sachet. Soak the gelatin for 12 hours in a third of a glass of water. After the allotted time, stir gelatin, two tablespoons of flour, one - sugar in ⅔ glass of water. Bring to a boil, cool, store in an airtight container in the refrigerator.

Homemade cakes with decorations that look like various figures, flowers from food mastic are not only a hobby, but also a small business. To ensure that the entire decor adheres securely to the baking surface and retains its shape, food glue is used. People buy it, often not knowing that glue can be made at home. We use starch, from four tablespoons of which we boil jelly in a glass of water and keep warm until it becomes thick and viscous. According to the second method, we boil a glass of sugar in a glass of water. You should get a slightly undercooked toffee caramel, which is food glue.

The composition of the glue

The simplest is considered dry cement glue with the addition of additives - anti-freeze and moisture-retaining. The basis is Portland cement, and quartz sand is used as a filler. PVA glue is also added to the "artisanal" mixtures for laying tiles, which increases the elasticity of the mortar.

Reference! Portland cement is a type of cement with increased binding properties and the ability to quickly harden both in air and in an aqueous environment.

More complex types of glue contain:

latex - serves as a binder, gives the composition plasticity;
epoxy - suitable for working with wood, ceramics and metals;
polyurethane - provides a high degree of adhesion to any surface;
synthetic resins - promote quick setting and drying, suitable for finishing moving surfaces;
synthetic rubber (neoprene) - is part of liquid nails.

How to make edible glue

How to make protein-based food mass:

Carefully separate the whites from the yolks. The number of eggs depends on the amount of glue required.
Beat egg whites until peaks with a mixer. All utensils must be free of fat. You should start at low revs, then add speed. For best results, whisk the whites cold.
Add a pinch of citric acid and powdered sugar to the whipped white mass. It is allowed to replace citric acid with tartaric acid.
Stir until thickened.
Edible glue should be refrigerated for 4-5 hours before use. The mass must be covered with cling film so that it does not wind up.

Another recipe for glue for mastic, only based on flour:

Boil 2 cups of water.
Stir 0.5 cups of flour with a little cold water to make a thick gruel.
Pour the flour mixture into boiling water.
Boil a little and remove from the stove.
Add 3 tablespoons. sugar, stir.
Cool it down. Ready! Start decorating cakes and pastries.

Classification

All adhesives can be divided into several groups depending on the main component from which they are made. Each group of formulations is described in more detail below.

Polyurethane

Features of polyurethane adhesive mixtures are as follows:

characterized by a high degree of elasticity, capable of gluing any type of surface, even different ones, for example, glass with metal;
used if necessary to provide additional waterproofing;
some compositions are capable of expanding after hardening, therefore, they are not always suitable for laying ceramic fragile tiles;
are characterized by high strength, elasticity and resistance to sudden changes in temperature conditions.

There are one-component and two-component formulations. One-component polyurethane adhesive hardens due to the influence of the environment, enters into a chemical reaction with air. Two-component formulations harden by combining components after mixing in a certain ratio.

Cement

On sale, this type of glue can be found dry in bags. The main composition is Portland cement, sand and modifying additives. Additives in the glue are not more than 5%. Due to the sand, the glue is durable and at the same time has a low weight, which provides a low load on the base.

Depending on the modifiers that are present among the components of the glue, its properties differ:

when plasticizers are added, the solution turns out to be viscous and plastic;
due to antifreeze additives, a high level of frost resistance is achieved. Such adhesives are used for outdoor work;
water-retaining additives prevent moisture from evaporating and give the surface an increased level of strength.

There are two types of cement-based adhesives:

thin layer. They are used in works where the tiles are laid on a base with irregularities of no more than 1 cm;
thick layer. They are used if it is necessary to level the differences up to 3 cm on the base, for example, if there is a need to tile the walls, then using thick-layer cement glue, you do not have to engage in preliminary plastering and leveling the surface.

Important! Be sure to evaluate the level of elevation differences!

Dispersive

Produced in the form of a paste-like homogeneous mixture, thick in consistency. Mix immediately before application. They can only be used on a flat concrete or plasterboard base, previously plastered.

It can be used to lay tiles both on the wall and on the floor. Their composition is an aqueous dispersion based on acrylic, latex or polyvinyl acetate.

Epoxy

The composition of the epoxy type of glue is resin and hardener. The components are mixed immediately before use. Due to the hardener, the mixture is strong, pressure-resistant, because the resin itself does not have such characteristics.

The main advantage of this type of material is a high level of adhesion.

Used for laying ceramic tiles on a wooden or metal surface.

8 Minor repairs in everyday life - we use improvised means

Occasionally you have to glue things that are made of less common materials, or repair something. Some tips will help you get out of this difficult situation. If you want to join organic glass (plexiglass), we make an adhesive composition from it. Prepare a small amount of small plexiglass sawdust, fill a vial with them. We dilute acetone and amyl acetate equally and fill in organic glass sawdust with this solvent. We put in a warm place, wait for complete dissolution. If we use only acetone, the plexiglass will not dissolve completely, but the composition is suitable for work.

Casein dissolved in liquid glass can be used to glue glass, porcelain and faience

In everyday life, there is often a need to glue glass, porcelain and earthenware products. Take liquid glass and dissolve casein in it - the repair tool is ready. For porcelain and faience, a gypsum solution on egg whites is especially good.

It thickens almost instantly, we work quickly and carefully. Preparing another composition for earthenware and porcelain

Beat the egg whites, refrigerate for 24 hours. Separate the settled protein, rub thoroughly with quicklime until the dough is obtained. We glue quickly, spreading in a thin layer.

You can glue linoleum, tiles with unusual instant glue. We crumble the foam and fill the place that needs to be glued with it. We spray the foam plastic with acetone, which immediately begins to melt, and press the parts to be glued. This is a very convenient glue for the sole. We push the foam balls into the place requiring repair, drip acetone and press down.
