Bakelite varnishes are used for coating various surfaces, their main purpose is to protect equipment from the effects of агре6ссивной industrial water, weak and strong acids. Also, these paints are used for painting gas tanks and as connecting means for laminated plastics. In contrast to many analogues, bakelite varnish may be used for impregnation and even gluing pieces of highly adhesive materials.
For preparing bakelite lacquer is used of the phenol, formalin, ammonia water and ethanol. Phenol is an organic compound which is completely soluble in water and solidifies at temperatures above 40o C. formalin is a transparent liquid with a low degree of reactivity, phenol is considered a poison. The ammonia water is 20% aqueous solution of ammonia. Ethyl alcohol or ethanol is a colourless thin liquid, the product of the distillation of carbonaceous products. The result is a transparent solution that can be as red, and brown.
Bakelite varnishes are of different varieties:
- Lbs-1 and lbs-2 (top grade),
- Lbs-4,
- Lbs-5,
- SBS-1,
- Lbs-8,
- Lbs-16,
- Lbs-20 lbs-29.
Depending on the brand varies with the percentage of the above substances in the resin varnish. In the result, change its properties and functions. So, for example, varnish lbs-4 is used for the production of plastics with mineral fillers and SBS-1 for the production of wood plastics and plywood.
The main task of bakelite varnish is the creation of a thin protective film, which may consist of inorganic and organic polymers. This film does not change the color of the surface, hides imperfections and prevents the penetration of moisture into the product. A feature of this Polish is the vegetable oil part of it. Also, the bakelite varnish is cellulose, which is pre-processed.
The use of bakelite varnish at home is complicated by the fact that after applying the Polish on clean and dry surface must be exposed to heat, gradually increasing the temperature to 160оС. In the end (after 20 seconds) will be the polymer film, which will last a long time if the ambient temperature is above 20 ° C, and also excluded a direct effect of sunlight.

The shelf life of the lacquer should not exceed three months from the date of its manufacture.
