How to work with resin?
When working with resin, the main thing is to carefully observe the proportions, since an insufficient or, conversely, too large amount of hardener has the most negative effect on the functionality of the final composition. With an excess volume of the hardener, the composition loses its strength. In addition, excess can be released to the surface as it hardens. With a lack of hardener, some of the polymers remain unbound, such a composition becomes sticky.
Modern formulations are usually diluted in the proportion: for 1 part of the curing agent - 2 parts of ES, the use of equal proportions is allowed. Stir the epoxy and hardener thoroughly so that the consistency is uniform. Stirring is performed slowly, if the movements are sharp, bubbles will appear.
After pouring, wait until the resin hardens. In the course of polymerization, ES goes through several stages.
- Liquid state. The mixture of the main components easily drains from the stirring rod, this moment is optimal to pour the composition into the mold.
- Thick honey. In this state, the mass does not lie down in a thin, even layer, but easily fills a small volume.
- Candied honey. At this stage, it is not possible to carry out any actions with the resin, the only possibility of use is gluing surfaces.
- The transition from honey to rubber. At this point, the resin does not need to be touched, otherwise the formation of polymer chains can be disrupted.
- Rubber. The mass of the components has already entered into interaction and has ceased to stick to the palms, however, its hardness is not enough yet. In this state, the workpiece can be twisted and deformed.
- Solid. This resin does not bend, twist, or pick out.
Epoxy from different manufacturers has a different cure period, it is determined only empirically.
However, even without varnish, its surface looks glossy and shimmery.
How to choose and use epoxy for potting countertops
Countertops in any kitchen are constantly exposed to thermal shock, aggressive chemicals and sometimes mechanical shock. It is also necessary to take into account the fact that a decent thickness of the countertops is always poured. And don't forget about the decorative qualities of the finished product. The most acceptable formulations for work in this direction for beginners are MG EPOX STRONG and MG EPOX WHITE. More experienced craftsmen use the well-known ED-20 and a bunch of different plasticizers.
Countertops that imitate the sea and the shore are a small miracle that you can admire endlessly
How to use the epoxy resin selected for pouring the countertop, the step-by-step process of its creation, as well as a lot of important nuances, are described in detail in the video below.

ED for paints and varnishes
These include.
E-40 and E-40r are quick-drying resins for paints and varnishes. They can be included in the structure of varnishes, enamels and putties.
ES in the structure of varnishes and paints can be seen in most modern household appliances.
Aluminum, cast iron, lithium and cast steel work well with this material.
Assortment overview
Artline offers a wide range of epoxy resins, which allows you to choose an option for any purpose. A number of the most popular types can be noted.
Universal
Epoxy resin Artline Crystal Epoxy is transparent, so it is perfect for the implementation of any creative and renovation ideas. A distinctive feature of the product is the minimum viscosity, which guarantees easy air release, and also allows the resin to penetrate into the most difficult embossed surfaces. That is why this composition will be an excellent solution for priming or covering wood.
Artline Crystal Epoxy boasts incredibly fast polymerization, sometimes reaching 18 hours. It will not be difficult to work with such a composition, since it does not have an unpleasant odor.The fill thickness can be 12-15 mm.
Drawing and jewelry
A distinctive characteristic of this product is the presence of a viscous structure, which makes it possible to create volumetric shapes without problems. Among the main components are phosphor and various metallic pigments. Curing occurs as quickly as possible, which greatly simplifies the process of working with the material.
This type of Artline epoxy is crystal clear, and the potting thickness is 15 mm.
Thick fillings
The peculiarities of this product are its unique structure and low level of viscosity, which allows it to be used for high-build fillings. The developers managed to create a special formula that slows down the curing process. Thanks to this, in the process of work, there is no boiling, turbidity and other similar problems.
This type of epoxy from Artline is renowned for its crystal clarity and ability to withstand UV rays. The process of complete curing takes an average of 5 days, which favorably distinguishes the resin against the background of other varieties.
Ultraviolet
As you know, ultraviolet rays negatively affect any coating and material, epoxy is no exception. That is why the company has created a unique product that is still able to withstand the negative effects of UV rays and not deteriorate under their influence.
Injection plastic
Artline Liquid Plastic epoxy boasts a two-component system that was created to produce a monolithic plastic. The product is distinguished by the fact that it freezes extremely quickly - this greatly simplifies the process of working with it.
Artline Liquid Plastic was developed in order to produce decorative elements of furniture, as well as various souvenir products. The molding plastic of the company is characterized by a minimum viscosity, which makes it possible to use it in the manufacture of decorative elements of various shapes and complexity.
For pouring tables
A distinctive characteristic of this formula is that it was originally created for working with wood. Now the product is actively used for any porous surface. High-quality gas output ensures 100% transparent filling layers.
The resulting layer is extremely easy to process, and is also characterized by incredible strength and resistance to UV rays. Even after many years, such a surface will not lose its color and attractiveness.
Harm to health
Many users are concerned about the harmfulness of epoxy-based resins. After curing, the epoxy is completely harmless to the health of children and adults. But in the factory, when a substance hardens, particles of the sol fraction often remain in the composition, in a dissolved state it is dangerous to humans. However, in production, most of the processes are automated, so the risk of harmful effects of such products on the body is minimized.
But before curing, epoxy is characterized by toxicity and can have a negative effect on human health. The safety rules establish that it is possible to work with ES only with personal protective equipment. First of all, this concerns the respiratory system, since the resin releases harmful vapors before the final solidification. Work with ES should be in a ventilated room or in a room with an exhaust hood. Only a respirator can completely protect the respiratory system from inhaling their vapors. If you accidentally swallow the resin or get it in your eyes, seek immediate medical attention.
How to choose
In order for the epoxy resin from Artline to fully satisfy the wishes of the master and cope with the tasks assigned to it, you need to pay close attention to the selection process.First of all, you should pay attention to the type of resin
If this is a universal option, then it can be used for any work, including making jewelry
First of all, you should pay attention to the type of resin. If this is a universal option, then it can be used for any work, including making jewelry
It is also worth giving preference to this option, if necessary, to use the product in arts and crafts.
When choosing a universal option, it should be borne in mind that the thickness of the fill can usually not exceed 15 mm, however, in some cases, special types allow you to fill up to 50 mm. An attempt to fill in a larger volume may lead to boiling and a chemical reaction, as a result of which the surface of the material will be damaged, and the product may become completely unusable.
It is also worth choosing universal options if you need to get a high level of adhesion.
Another type is epoxy, which has a high viscosity, which allows it to form a raised dome during the pouring process. Such material will be an excellent choice when you need to create various patterns. The result is a fairly voluminous image. This effect is achieved due to the fact that the resin is applied in layers. This provides the artist with the ability to overlay multiple layers at the same time without fear of blending.
The choice of a specific type of Artline epoxy depends on the specific purpose for which it will be used:
For the treatment of countertops, a high-build fill is the ideal solution. In addition, such a material should not turn yellow during use, therefore it should be distinguished by its ability to withstand the effects of ultraviolet rays.
Where is it applied?
All types of epoxy can be divided into groups according to their areas of application. So, in the construction industry, epoxy is used for marking on highways, for decorating self-leveling floors. As a decorative material, it has become widespread in repair and finishing works. As a part of carbon and fiberglass, it has found application in repairing reinforced concrete structures and airports. Epoxy allows the bonding of bridge structures.
Resin is used to produce compressor blades and boat propellers. They have found application in the production of tanks and vessels. In mechanical engineering, resin can be used to correct casting defects. The density of the composition allows for the production of springs as well as springs. The polymer has found wide application in the field of aircraft construction - resin-based composite components are used to cover the wings and components of a jet engine, as well as empennage and competition of nozzles. It is from ES that fuel tanks and housings of parts in rockets are made.
Resins in the food industry have limited use - some compounds are used in the manufacture of cans. Due to its environmental friendliness, epoxy can be used in the household area without restrictions. It is used to create jewelry and interior decor elements. Resin is used to make small sculptures and furniture.
What it is?
Epoxy is an oligopolymer. It consists of a number of epoxy groups, which polymerize when reacted with a hardener. The most in demand are products obtained as a result of the synthesis of polymers based on bisphenol and phenol epichlorohydrin. ES has a liquid consistency, its specific gravity is 1.07 g / cm3. It can be transparent or colored, in most cases in stores you can find substances of white or yellowish-orange colors, they look like liquid viscous honey.
The product has high moisture resistance parameters, is able to adhere to a wide variety of substrates - metal, wood or uncured laminate. The shelf life is quite long - up to 1 year.
Of the minuses, the high cost of the product and the need to observe safety precautions during work can be noted. The product requires the use of additional components - hardeners, plasticizers
In addition, skill is required to create decorative coatings.
