Glue BF 2 – what is it where it is used

A specialized mixture of hydrocarbons is a transparent high viscosity fluid, with a yellowish, brownish or reddish weakly exposed shade, a characteristic pungent smell of alcohols and phenol -formaldehyde. This is a solution of resin on the basis of ethyl alcohol. Glue phenolivinyl acetate brand BF-2 variety I or the highest-specialized thermoreactive composition. The release of the mixture is regulated by the standard, the ratio of tarry substances and the Buthewara (polyvinylButiral) 1: 1. Glue is included in the analog group similar in chemical composition of substances, but differing in operational properties. The entire line of the BF shows resistance to high humidity, water, household chemicals. As a forming basis of glue, a solvent of the RFG representing a mixture of alcohols is used: ethyl, isopropyl or alumer in a mass ratio of 3: 1.

Beses are prized for their quick drying times and their ability to produce dense polymerized layers that can withstand significant shift loads and breaks with little consumption. BF-2 adhesive compositions are more economical to use, highly dependable, and produce dense, long-lasting adhesive seams when compared to other adhesive compositions.

BF-6 medical glue is a member of the BF group and is used for bandaging and localized bleeding. It functions as an antiseptic and skin barrier protector.

Composition and technical characteristics

The low polyvinylButiral content of BF-2 glue sets it apart from other brands (although some manufacturers swap it out for polyvinilac). The concentration of the polymer in butyralphenol adhesive increases with a higher digital index, which boosts the viscosity of the adhesive composition while degrading its strength properties. Chloroform, acetone, and ethyl alcohol dissolve polymerizable substances. Glue exhibits good resistance to other chemicals and does not fear exposure:

  • Acids;
  • Alkalis;
  • Fats;
  • Mineral;
  • Synthetic and vegetable oils;
  • All kinds of oil products.

A thick adhesive mixture is evenly distributed over the surface as a result of strong adhesion.

GOST 12708-77 states that the glue BF-2 is a polyvinyl chloride mixture that dissolves reserved phenol formaldehyde resins.

It is worthwhile to give the glue BF-2’s technical specifications more careful thought. The mixture creates a low-elasticity seam, and the glue gets harder as it polymerizes. The mixture is valued because of several unique characteristics:

  • Resistance to thermal exposure, on the glued surface you can put hot, adhesive seam without destruction can withstand heating to +200 ° C;
  • Like all adhesives, the strength of the shift is greater than the gap, with a shift, it outputs up to 20 megapascals (200 kgf/cm²), to gap 20% less effort;
  • The stiffness indicates the plasticity, the maximum bend of the seam does not exceed 3 mm;
  • The degree of drying is high, the seam forms thin due to the low content of dry components (no more than 17%).

Glue is used at room temperature and heating to +100 … 160 ° C. Work carefully, the mixture is fiery, easily ignites. The gluing should be engaged from open fire sources, in a well -ventilated room, since the components are toxic, are hallucinogens, when inhaled in large quantities cause poisoning and brain damage. It is better to store the composition at room temperature, with minus, the thick mass becomes too viscous, it is difficult to remove the glue from the tube. Ethyl alcohol is used as a diluent, pour it in small portions. If the glue immediately curls, then the polymerization process has already passed. The average glue consumption is 250 g per square meter.

The experimenters have established that using thermal gluing BF yields better results.

Instructions for use

The standard governs the glue’s range of applications. The mixture adheres flawlessly to wood, tiles, marble, and other natural building materials and can be used to restore decor made of non-ferrous metals, ceramics, glass, and much more. When it comes to fixing porcelain tiles, linoleum, and other contemporary flooring, BF is a need.

Although the glue was developed before a wide variety of polymers and composites were even imagined, the BF-2 is ideal for them and is far more useful than other adhesive compounds found in daily life. The risk of fires and toxicity are linked to use restrictions. If the adhesive becomes wet and leaves chemical burns on the skin, organic materials based on alcohol can be removed with water; simply replace the arm under the stream and pat dry.

The butyralphenol mixture has a slow polymerization rate, and the seam can take up to two days to dry. It is only after this time that items and parts can be deemed fully repaired, and the seam becomes sturdy and trustworthy.

When it comes to fixing porcelain tiles, linoleum, and other contemporary flooring, BF is a need.

How to prepare a gluing surface

The operating manual places a lot of emphasis on surface preparation. This directly affects the formed seam quality. Things to be aware of:

  • Glue does not interact with fats if the oily film is on a few microns on the surface, a good result will not work;
  • Thick glue on a smooth surface is collected in a drop, this is due to the internal stresses that occur during the evaporation of alcohol molecules;
  • Wood, other porous materials quickly absorb glue, this should be taken into account when applying an adhesive for building materials.

Suggestions regarding surface preparation:

  • From the repaired fragments, pollution, dust, moisture are removed;
  • It is recommended to degrease with acetone, alcohol or gasoline;
  • Glass, ceramics can be washed with warm water with soap or other detergent;
  • To increase the degree of sticking, smooth surfaces are treated with a skin, files, metal brushes to create roughness.

Once everything is ready and the glued elements are thoroughly dried, you can preheat them using the battery. They don’t start applying the adhesive mixture until after that.

It is advisable to refer to the manufacturer’s recommendations, as they typically list all glued materials and potential cleaners.

Features of application

A thick brownish mass is applied twice: first, a primer is applied to both connected surfaces using a brush, wooden blade, or other makeshift tool, and then the main layer is applied. For improved penetration, it is advised to wipe down wood, ceramics, and porcelain tiles using acetone or alcohol. To ensure that the seam is neat, the glue layer is applied as thinly as possible.

The second layer of glue is applied using the same technology and the glued elements are pressed after the first layer partially polymerizes for an hour, thickens, dries, and does not stick to the fingers. The degree of contact between the fragments determines the seam density; various ties are used to improve pressing, as are clamps, vices, and other compressive tools.

"Hot" technology is also utilized in order to operate with BF-2:

  • Drying of the primer layer is accelerated with a hairdryer or the parts are placed in a furnace heated to +95 ° C, an aging time for 15 minutes;
  • Dry the seams at a temperature of up to +160 ° C for two hours, the degree of heating and exposure time depends on the type of glued materials.

Strong compounds can be obtained if the suggested distance between the glued frequent frequent is less than 50 microns.

How can I replace BF 2

In the domestic analog market, there is no comparable BF-2. Other comparable-technical components are used by foreign manufacturers. While dried varnish is commonly used for tree glue, BF-2 holds much better. It is improper to swap out the second BF for the fourth or sixth because the seams become weaker the more polymerization components there are in the mixture. Ceramics and metals are not used in medicine at all; only certain kinds of plastic are.

When working with ceramics, glass, and wood, two-component epoxy resin, or "super-chain," is frequently used in place of the BF-2’s one-component composition. There is currently no substitute for the distinctive Soviet glue used when working with metal. Other combinations that are quite different from BEEF—phenolivinyl acetate glue—can be used instead; it’s a versatile and useful glue.

BF-2’s scope is essentially infinite. You can glue a broken vase or figurine, or apply a metal patch to a leaking tank. In the event of tile breakage, floor and wall coatings, as well as plastic and metal components working for compression or bending, are repaired using the composition. The seam on glass and porcelain is nearly undetectable and maintains its hardness and tightness while in use.
