PAINT "Serebryanka" BT-177 (GOST 5631-79) is used for painting structures and products that are operated outside in atmospheric conditions.

Purpose of the material

The paint BT 177 (silver) is designed for the protection and decoration of metal, wooden, concrete structures and products that are used in an open atmosphere.

Benefits

BT 177- paint, which has the following number of advantages:

- it is capable of giving the surface a decorative appearance;
- to protect the surface from negative atmospheric influences;
- has an anti-corrosive effect;
- drying is fast enough;

Main characteristics and properties of the material

BT 177 - paint (enamel), which consists of two main components: BT-577 varnish and aluminum powder. Before use, they mix. This paint is a material that is sufficiently resistant to weathering. It is applied as a primed surface, and without preliminary treatment. The paint has excellent adhesion to the metal, when drying it is possible to obtain a brilliant, mirror, elastic, temperature resistant coating that can withstand a temperature of 200 ° C, among other things, it perfectly protects against rust, high air humidity and the action of solutions of complex substances contained in Water, on the painted surface. BT 177 is a paint that is applied using a brush or roller or sprayed onto a product. Drying of the paint occurs both under natural conditions and by using hot drying.

Appearance of coatings

After the paint dries, the surface acquires a silvery color with an even structure that does not have any wrinkles or pockmarks.

Solvent

These paintwork materials, if necessary, are diluted with white spirit, solvent, turpentine, or their mixture in the desired ratio (1: 1).

Application of paint on the product

Before applying the paint, the product should be prepared. If it was previously painted, it should be cleaned and dried. Only after the completion of these actions can you paint the surface with a roller, brush or spray. These paint and varnish materials are applied as one or two layers, the air temperature during application of the paint can vary from +5 to + 35С and humidity up to 80%. When using paint at a low temperature, please note that the temperature of the material should be at least + 15C.

How much paint is consumed per layer

On the painted surface of 1 square. M. It takes from 110 to 130 grams. Actual consumption, as a rule, depends on how well the surface to be painted is prepared qualitatively, what method of painting is applied and what is the professionalism of the personnel.

One layer of paint is 20-25 microns thick and depends on the method of staining and the qualification of the personnel.

How to dry the painted product?

The drying time of the paint at an air temperature of 20-22C is 15-16 hours; At a temperature of 100-110 C, the paint is dried for 30 minutes, the coating should be held for 30 minutes at room temperature. After performing hot drying before use, the painted coating should be kept at least 3 hours in air, the temperature of which is 18-22 ° C.

Coating service life

If all the requirements for surface preparation, application of paint (primer layer and 2 layers of paint), as well as drying of the painted product are met, exploitation of the coating in a moderate climate is possible up to 2.5 years.

Main technical characteristics

BT 177 paint has the following characteristics:

• Drying at a temperature of 20-22 ° C to the third degree is not more than 16 hours.
• At an air temperature of 100 to 110 ° C - no more than 30 minutes.
• Elasticity of the film with a bend of not more than 1 mm.
• The non-dried film has a hiding power of not more than 30 g / m2.

Recommended color scheme

The paint of BT 177, the characteristics of which are indicated above, color the metal products as follows:

• 1 layer - primer (eg GF) on the rusty surface of "Unicor", or with the use of a single layer of the corrosion converter;
• 2 layer - one (or two) layer of this type of paint.

In the absence of a primer, you can simply apply two coats of paint.

How should I store it correctly?

The components of the paint (varnish and duralumin powder) will be stored in hermetically sealed containers protected from moisture, the effects of temperature effects (direct sun and heat rays) at air temperatures from minus 40C to plus 40 C.

What kind of packaging is produced?

The varnish that the paint consists of is sold in cans or industrial containers; Powder aluminum - in drums. Packages are large, which contain 15, 25, 57kg, or small, weighing from 0.8 to 2.8kg.
