The main characteristics of the bitumen varnish BT-577 and its use

Welcome to our paint and paintbrush resource guide! This article delves into the realm of bitumen varnish BT-577, examining its primary attributes and real-world uses.

Bitumen varnish, also known as BT-577, is a specialized coating with outstanding resistance to weather and wear. Because of its capacity to offer enduring protection against corrosion and environmental factors, it is frequently utilized in a variety of industries, including marine, automotive, and construction.

The high viscosity of BT-577 is one of its primary qualities, as it facilitates easy application and guarantees even coverage across surfaces. Because of this, it can be applied to a variety of substrates, such as concrete, wood, and metal.

Bitumen varnish BT-577 has good adhesion as well as protective qualities; after application, it forms a solid bond with the substrate. This prolongs the life of the coated surface by reducing the likelihood of peeling, cracking, and flaking.

Furthermore, BT-577 has strong chemical resistance, which qualifies it for settings where exposure to corrosive substances or other contaminants is a risk. This increases its suitability even more for a range of outdoor and industrial applications.

All things considered, bitumen varnish BT-577 is a highly adaptable and dependable coating solution that is highly valued for its resilience to weather, longevity, and ease of use. We will examine its use in various industries and offer helpful application and maintenance advice in the sections that follow.

Main Characteristics Use
Waterproofing For sealing roofs and foundations
Durable Protection against corrosion for metal surfaces

Compound

It is produced in compliance with GOST 5631-79 using oil bitumen as the base material. Mineral oils, organic solvents, resins, high molecular weight oil components, and drying additives are additional ingredients. Synthetic components are included in the composition of the BT-577 to enhance its brilliance and speed of freezing of the varnish layer.

Turpentine, solvent, or white spite are examples of dilutors.

An aluminum paint of the same brand can be made by mixing eight parts varnish with two parts aluminum powder. The actual varnish material is created in phases. First, bitumen, high molecular weight oil components, and flax are combined to form its base. The remaining ingredients are then combined. The final composition is examined for impurities, color, viscosity, and non-volatile material content. This is done in a dedicated mixer. After that, it is filtered and cleaned in a centrifuge. Additionally, tanks are filled with varnish spills. After that, it was sold and transported. A certificate of quality is given to each batch.

The viscosity of Kuzbass varnish increases by 10% after extended storage; to restore its original consistency, add a solvent before using again.

The composition makes the metal it processes more resistant to temperature variations and the effects of atmospheric precipitation. The varnish layer that has dried is not damaged by low temperatures or UV radiation. both freshwater and seawater resistant.

Metal treated with BT-577 has a long-lasting resistance to rust.

It will not let them apply to "healthy" areas if there are already signs of rust. Because of the composition’s antiseptic qualities, it prevents the growth of mushrooms, mold, and microflora on the surfaces it processes. BT-577-coated wooden bases are shielded from decay.

Consumption

Make sure you determine how much material will be needed for the task before making a purchase.

When doing calculations, keep in mind that the BT-577 varnish for metal has a 0.15 kg/m³ consumption.

It takes a lot of mixtures to process a single layer, so manufacturers advise applying two layers. To calculate for this, multiply 150 g by the area that needs to be processed, then double the result.

Fields of application BT-577

  • The use of bitumen varnish is justified in construction, industrial spheres, everyday life, agriculture.
  • It is used to process working devices, technology. As well as for objects that are subject to transportation or short -term storage for up to six months.
  • The agricultural equipment is often opened with varnish, subject to off -season canning.
  • BT-577 Metal and wooden surfaces are usually processed.
  • You can use it to protect the slate, brick, other materials.
  • For the prevention of decay, the composition is applied to wooden pillars and houses.
  • Protect the walls, floors, ceilings of cellars or basements from moisture.
  • Used in the arrangement of garages and pools.
  • It is used in decoration, the old surfaces treated with BT-577 are especially spectacular.
  • The composition has a high degree of adhesion with any surface, therefore it can be used as a glue.
  • They are connected by materials in rolls and sheets.
  • Based on the varnish, paint is made.

How to apply correctly

The material to be processed must be completely free of corrosion indications, dirt, oil and fat stains, and salt deposits before applying the BT-577 bituminous varnish. If covering the tree is required, the base needs to be free of any mud, mold, or signs of decay. You cannot prime the surface that will be varnished.

Kuzbassklan needs to be diluted if, upon opening the container, it becomes too thick.

You can use multiple of the listed means simultaneously.

The mixture needs to be well combined after the solvent is added, then left alone for ten minutes. This is sufficient to cause the product to release air bubbles.

Any of the surfaces that need to be processed can have varnish applied using an airbrush, brush, or roller.

You can dip the tool into varnish if you’re varnishing small surfaces. It is preferable to employ the technique if the composition opens up the horizontal walls of a large space.

Work should be done in a space where the air temperature is between +5 and +35 °C. In these circumstances, a single layer dries at an average rate of one day. The composition hardens in just twenty minutes if dried at the boiling point of water. Applying the product in two layers is preferable. There should be enough time between applications to allow the previous layer to fully dry.

Storage and safety

The toxic combination of chemicals and solvents in BT-577 brand varnish makes it dangerous for people to use. You must use it safely and take all necessary precautions. To protect the respiratory system, wear a gas mask or respirator while working. Air ventilation is essential when working indoors. The best place to varnish something is outside, if at all possible. You must wear special clothing to protect the rest of your body and rubber gloves while applying the composition of the hand. It is necessary that you put on the protective glasses.

  • If the lacquer mixture gets on the skin or mucous membranes, they must be urgently washed with a large stream of water.
  • The skin can be wiped with a solvent, the remaining of which is washed off with water and soap.
  • In case of accidental varnish in the gastrointestinal tract, it is necessary to provoke vomiting and rinse the stomach with a large amount of the drunk fluid.
  • It is also necessary to accept any of the available sorbents.

Composition of BT-577 explosive and fire. It needs to be kept in a factory container that is securely closed, away from heat sources and open flames. It is not possible to heat the container. It should be kept out of direct sunlight, in a cool, dry place away from heat sources, away from food, and away from young people.
