Varieties of adhesives from a leading German manufacturer
On the territory of Russia, the products of the German concern Henkel Group, which occupies a leading position not only in the domestic but also in the world market, are widely represented.
The Henkel Group's Loctite range of adhesives includes a wide range of products with very different formulations - from cyanoacrylate, acrylic, polyurethane to epoxy, butyl and UV curing.
Loctite adhesives with organic and inorganic base, single and multicomponent, as a rule, have a wide range of applications and can bond various types of homogeneous and dissimilar materials.
Equipment
Finally, we would also like to note the equipment manufactured by Loctite for gluing various parts. Sometimes it is enough to use a tube for the procedure, but in most production tasks this is not enough. Then a special dosing of the composition is used using automatic equipment.
It should be noted that the company offers not only ready-made solutions. The company can design and create equipment, taking into account individual requirements. In the reviews, consumers highly appreciated the quality of the proposed solutions.
Additionally, you can watch a video with tips for applying Loctite adhesives.

How to remove BF glue
The medical version of the glue dissolves on its own within 2-3 days. Or the elastic film can be easily removed if you pick it up on one side and gently pull it up.
To remove technical compounds, a mechanical method can be used (if the surface allows). If there is a risk of damaging the surface, use alcohol or acetone-containing liquids.
To do this, moisten the cloth with alcohol or acetone, apply generously to the glue spot. Leave on for 20-30 minutes. Then apply the thinner again and gently clean with a rubber trowel or flat plastic part.
Brief description of the brand
Loctite is a brand with a long history of making effective adhesives. Among the assortment of this company you can find adhesives for almost all materials existing today.
Their use opens up unique opportunities for a person in the field of joining difficult-to-stick materials.
Combining excellent performance and affordability, loctite adhesives have become very popular in the domestic market. They provide reliable and fast bonding of a wide range of different materials: metal, plastic, elastomers, rubber, porcelain, and the like. In addition, they do their job perfectly well in the case of wood, leather or textile products.
Loctite glue
For maximum effectiveness of the substance, the surfaces to be glued will need to be cleaned and degreased using special agents. And the excess glue is removed with nitromethane or acetone.
Features of the application of Loctite adhesives
Fast bonding speed is the hallmark of Curing Instant Adhesives based on cyanoacrylates.
For applications requiring high stress resistance, it is advisable to use epoxy and acrylic adhesives, which provide high bond strength.
Also, a strong connection with little elasticity and filling large gaps can be obtained using polyurethane compounds.
To smooth out dynamic loads, it is recommended to use adhesives containing silicone.
Polymer adhesives make it possible to obtain elastomers that firmly bond with any materials and perfectly resist the negative impact of the environment.
Adhesives containing butyl rubber are able to demonstrate excellent plasticity even at low temperatures and reliably bond with many types of materials.
For assembly industrial processes, structural adhesives of general purpose are indispensable, which can provide a combination of quite different properties.
Transparent adhesives with UV polymerization can significantly speed up the technological processes of joining parts. Their use has a positive effect on reducing the cost of the process.
Instructions for use
Depending on the characteristics, different types of adhesives have their own application characteristics. There are two application options:
Thermal treatment for BF-19, 2, 4, 2H, 4H solutions - we clean the surfaces, degrease them (if necessary, sand them with sandpaper). Apply a 3-5 mm layer of glue. We give time for the initial setting (about 1 hour). We firmly squeeze two parts with an adhesive layer, heat up to 120–135˚С for 50–70 minutes. Let it cool at a temperature of 18-23˚С.
For BF-88, the heating temperature is up to 90˚С for 30 minutes.
- The instructions for use by the cold method are the same for all brands of glue. Apply a layer of glue to the prepared surfaces and let it soak for 20-30 minutes. Then we apply another layer 2–3 mm thick, fix the elements to each other and leave them to fully adhere for 24 hours.
- BF-6 is applied to a dry area of the skin when the bleeding has stopped. The damaged area and the surrounding skin (1–2 mm) are covered with a 2 mm thick layer of glue and allowed to dry completely.

Instant formulations
Super glue Loctite cures quickly in a small gap between the surfaces to be bonded. The composition is used to create a strong connection between small elements. The material can be different. Instant formulations can be supplied in gel or liquid form.
There are a number of Loctite adhesives available to suit different application conditions, loads and gaps. The formulations have strong adhesion to a variety of materials, creating a strong bond.
Advantages of instant compositions:
- simple application;
- no solvents in the composition;
- with small contact zones of the surfaces, high strength is provided;
- dissimilar surfaces can be connected;
- sets quickly.
Next, we will consider typical samples, we will give the markings and photos.

Varieties
Depending on the intended use, chemical composition, the following types of adhesion component are distinguished:
BF-2
Such a solution is used for small and large repairs and installation of elements made of natural stone, non-plastic metals, plastic, ceramics, wood.
Of all the varieties, bf 2 glue creates the least elastic seam. Therefore, it is applied to surfaces that are resistant to shear, do not deform.
The solution polymerizes quickly, but for application its temperature must be at least 20 ° C.
The solution is recommended for use in bathrooms, saunas, as it is not susceptible to the influence of chemicals, the formation of mold and fungal deposits.
BF-4
The substance is used to create models, in applied art - for crafts from ceramics, leather, fabric, wood, plastic. BF 4 glue is resistant to the action of chemically aggressive solutions, temperature drops from -55 to + 160 ° C. Therefore, it is suitable for repairing industrial equipment, mechanisms, reagent tanks.
The composition creates a particularly strong seam when heated to + 160˚C or dried within 24 hours. BF-4 glue differs from BF-2 in greater elasticity, but less heat resistance.
BF-2N and BF-4N
In terms of their properties, BF-2N and 4N are similar to grades 2N and 4N and can replace each other. The only difference is that BF 4 contains polyvinyl acetate resin. This component provides a more elastic seam. When joining parts subject to deformation, vibration loads or shear, it is preferable to use grade 4H.
Industry standard “H” grades are for ferrous applications. Without "H" marking for working with non-ferrous metals.
BF-88
Has a wide range of applications in everyday life and industry. Due to its moisture resistance, good penetration into the surface, it can be applied as a wall primer for repairs. The glue seam is elastic, at the same time it can withstand drops from -30 to + 70˚С.
Non-toxic, therefore suitable for closed, unheated rooms. Connects parts made of rubber, leather, metal, plastic, wood, glass, ceramics, stone. With the help of BF-88, they repair shoes, leather goods, and restore ceramics and wood items. Curing occurs both when heated and dried.
BF-19
The glue is mainly available in standard tubes. In terms of technical characteristics, it is similar to BF-2N and 4N. But it forms a more elastic and thin adhesion seam. Dries quickly, may cure when heated. When applied cold, it is suitable for bonding rubber, rubber, cardboard, leather and suede. With the thermal method, it creates a stronger adhesion and connects metals, wood, glass (including plexiglass), granite, tiles. The seam does not crack, does not shrink.
BF-6
The most famous brand of BF compositions. It is used for medical purposes for external use. Binds and forms a protective layer on wounds, burns, stitches after surgery (surgical glue). With the help of medical glue at home, you can fix dentures, glue false nails or curls.
Although extremely rare, glue causes allergies.
