Properties, advantages and recommendations for applying BT-177 paint

BT-177 paint is often called “silverfish” - it is under this name that it is familiar to most people. The tool is intended to protect metal products from damage, especially if they are used outdoors and when changing temperatures.

Material Purpose

The BT-177 silver enamel is a suspension in consistency, it includes bitumen-based varnish and aluminum powder. Serebryanka is best used for metal - paint helps prevent rust on the surface. Application of the product is also possible on products made of other materials - wood, plastic, concrete.

Aluminum Powder Paint

The tool is widely used for exterior and interior use. It has excellent refractory properties, therefore it is used for coating furnaces, boilers, other products and structures made of ferrous and non-ferrous metals, which have to be operated at elevated temperatures. Due to the presence of aluminum, paint cannot be used in children's rooms, hospitals and other rooms, which have high safety requirements.

The material is used for painting:

  • country equipment;
  • car drives;
  • pipes;
  • gate;
  • profile fences;
  • columns.

Do not use the product when heating surfaces in excess of +90 degrees. It is not used for painting containers for storing water, it is not applied to oil, oil-bitumen, alkyd coatings, to nitro enamels.

Paint advantages

Previously, silver was produced in one color, corresponding to the name. Now other shades are being produced: there is a golden, bronze, copper paint on sale, dyes are additionally introduced into them. Due to this diversity, the product gives excellent decorative qualities to products, the appearance of surfaces is significantly improved.

Other advantages of the material:

  • protection against harmful factors, including natural ones;
  • resistance to weather extremes;
  • corrosion protection, stopping an existing process;
  • quick drying;
  • long term of operation.

The water-repellent properties of the material after painting the products make it possible to simplify the care of them. Serebryanka does not respond to washing with SMS, abrasives, cleaning products, does not crack and does not crumble during friction. The paint will retain its excellent appearance for 3 years after application, after the surface it is necessary to tint.

Properties and characteristics

The tool is prepared according to GOST 5631-79. Each batch passes the certification procedure and receives the necessary certificates of conformity and quality certificates. The certificate indicates the percentage of components. The paint has a peculiarity - the composition is prepared immediately before pouring from aluminum powder (15 - 20%) and bitumen varnish (80 - 85%), it is sold in the form of two components (powder and varnish separately).In production, finely divided PAP-2 powder or larger PAP-1 powder is used.

  • viscosity on the instrument viscometer VZ-4 - 18 - 35 s;
  • solids content - 40%;
  • temperature for application + 5 ... + 35 degrees;
  • consumption per 1 m2 - 80 - 130 g / sq. m;
  • layer thickness - 20 - 25 microns;
  • bending elasticity - 1 mm;
  • hiding power of the film - 30 g / sq. m;
  • film drying time at a temperature of +20 degrees - 16 hours, at a temperature of +100 degrees - 30 minutes.

Before using the product, it is better to apply a primer, but a direct method of staining without primer is possible. Turpentine, white spirit, and solvent are used for dilution.

Mode of application

Before using the paint, the composition must be thoroughly mixed. Next, the working viscosity is checked, if necessary, solvents are added (it is best to dilute the thickened paint with solvent). The amount of solvent is not more than 1: 1 by weight.

DIY silver cooking

Before applying make sure that the surface is completely dry. The methods of pneumatic spraying, applying with a roller, brush are applied. The number of layers - 1 - 2, no more. It is important to consider the recommended temperature, humidity not more than 80%. The temperature of the base itself should be at least +15 degrees.

The surface is dried for at least 16 hours, only after this product can be operated. If possible, do hot drying for 30 minutes, after which they withstand the coating for another 3 hours at room temperature.
