Work properties and composition

The BF-2 glue’s technical and technological characteristics state that a low-elasticity seam forms when this adhesive mixture is used.

Additionally, it can withstand temperatures as high as 200 degrees Celsius.

These products’ functional characteristics can also be linked to:

• The level of strength of the connection at shift loads: 19.5-20 MPa.
• The bend of the glue seam after complete curing: no more than 3 mm.
• The degree of viscosity at 20-25 ° C: about 30-50 PA · C.
• The percentage of dry balance: no more than 17%.

The degree of viscosity of the glue BF-2 increases when it is stored at lower temperatures.

Crucial! The mixture needs to be warmed up to 20–25 OS right before use (heating should happen naturally in a warm room; forced heating is prohibited).

The product is highly resistant to the harmful effects of mold, fungus, non-aggressive liquids, and chemicals. Moreover, common solvents like acetone, gasoline, alkali, alcohol, and liquid based on them have no effect on it. As a result, the products can be used for a wide range of tasks, from basic home gluing tasks to the dental medical field.

GOST 12172-74 was utilized by manufacturers in the production process. Phenol-formaldehyde resin materials are used to make Glue BF-2, and polyvinylButiral or polyvinlacetal is an essential ingredient. There are no additional ingredients added to the adhesive solution’s composition. Because other manufacturers do not use these components in the production of adhesive solutions, there are essentially no equivalent products available in Russia because of their composition.

The field of use

According to the instructions for using BF-2 glue, the material and products that are not subject to dynamic loads or that move while in use should be connected using this solution.

Crucial! If the object to be glued is stationary, BF-2 glue can be applied. If not, the glue seam becomes distorted. Once hardened, its elasticity is reduced.

It is acceptable to use BF-2 glue to join materials:

• Metal.
• Marble.
• Tiles.
• Glass.
• Porcelain.
• Wooden.
• Polymer.
• Ceramic, etc.D.

It is permitted to use two different products (such as plastic and wood, glass and ceramics) with BF-2 glue.

Crucial! According to the leaders in charge of the BF-2 glue’s action and operation, the composition should be applied in two layers to guarantee a high concentration of gluing materials.

For the repair of various radios and audio equipment during the USSR era, glue BF-2 and BF-4 were employed. The adhesive composition of this kind may theoretically be applied to restored or restored surfaces as paintwork or impregnation.

Instructions for use

Following the guidelines below is required when handling the BF-2’s adhesive composition, per the manufacturer’s recommendation:

1. It is necessary to prepare glued surfaces before work. It is recommended to pre -roll the surfaces to increase adhesion, degrease, remove oil spots, pollution, dust.
2. Glue BF-2 must be applied to both connected surfaces. Application should be made maximum with a possible thin layer, which should be evenly distributed along the area of ​​connection of parts. You can apply the mixture with a brush or any other suitable improvised tool.
3. As soon as the first layer of glue BF-2 or BF-4 hardens, it is necessary to apply the second layer using the same technology.

If surfaces are joined using a cold glue technique, the products must be joined right away following the application of the second layer. To make the connection dense and inexpressible, the surface should, if at all possible, be pressed with a vice.

Crucial! It will take one to two days for the seam to harden. You cannot begin to use glued parts until this time has passed.

For BF-2 glue, all that needs to be done is rinse the mixture under warm running water. Since many adhesive solutions in this series are used in medicine, they are non-toxic and cannot be harmful to human health, so no additional processing is needed.

Glue BF-2 is an adaptable adhesive that has a broad range of uses and excellent bonding properties. This article examines the various types of BF-2 glue and describes how to use it for both home and industrial projects. To get the best results, it also offers detailed instructions on how to apply the glue correctly. The longevity and caliber of your work can be improved by using BF-2 glue correctly, whether you’re working with ceramics, metal, or wood.

Features of transportation and storage

The BF-2 and other glues in this series can be kept in completely closed and sealed containers. Storage needs to be done in spaces where there is less chance of an open flame or fire.

D. Transportation is permitted to be done in an environment with negative air temperature. Transportation of compositions of this kind can be done via a variety of modes of transportation, including air, road, and rail.

It is necessary to keep glue BF-2 out of children’s reach and in a dry, dark place. The adhesive composition must be stored inside its original factory packaging.

Analogs of glue BF-2

There were no BF-2 glue equivalents available in specialty stores within the domestic market. Such adhesive mixtures are just not available for purchase at this time. This is because phenol-formaldehyde resin is just not used by manufacturers in the modern era. This adhesive solution is genuinely exceptional.

Many experts also take into account the Super-cement product as an alternative because of its comparable working properties and application. However, when it comes to adhesion, seam strength, and many other operational aspects, the "super-cement" falls short of the BF-2 glue (particularly when it comes to gluing products and metal parts).

If you’re not interested in using BF-2 glue or couldn’t locate it for sale, you can use any glue solution made with epoxy resin as a substitute. Epoxy adhesive compounds are capable of handling the identical tasks that BF-2 glue was designed to handle. Nevertheless, solutions containing epoxy resin are less safe and more toxic, so extreme cautions must be taken when using them.

Because of its resilience and strong bonding qualities, Glue BF-2 is a versatile adhesive that is used extensively in a variety of industries.
