Areas of use
Bitumen paint is used in various industries, including the construction and electrical industries. It is used as a protective coating for the following works:
- In construction - for waterproofing treatment of wooden, brick, reinforced concrete structures. Paint provides protection from destruction (rotting and corrosion).
- In electrical engineering - for painting current-carrying lines (protective grounding busbars).
- In shipbuilding - for processing the bottoms of ships and other floating craft.
Types of dyes of this class are used in furniture production, protecting the surface of finished products from damp fumes.
Previously, these compounds were used as a waterproofing coating for the bottoms of boats and schooners. But with the advent of modern technologies, the scope of application of bitumen dyes has expanded. Their range has become richer.
Application Features
Protective compounds based on bitumen are used for painting various structural elements. They are supplied ready-made and do not require additional preparation before use.
When applying to the surface, use soft brushes, as well as special spray guns or other similar tools.
The drying time of bitumen paint is determined by the specific type of composition and can vary from 6 to 24 hours.
Based on the results of familiarization with the features of this dye, the following conclusions can be drawn:
- In construction, bitumen dyes are used as waterproofing coatings.
- These compositions are easy to use and convenient for restoration.
- The low price of protective compounds is available to everyone.
Bitumen dyes contain chemical components that lead to consequences such as dizziness and skin irritation.
Therefore, for safety reasons, it is recommended to use respirators and thick gloves when working with such material.
Manufacturing methods
For the production of protective paints, special grades of bitumen are used: “G” (GOST 21827-76), refractory compositions of the “rubrax” type, manufactured in accordance with GOST 781-68.
Typical methods
Bitumen compositions of grade “G” are produced using tar oxidation technology. This allows you to obtain mixtures with a melting point from 125 to 135 degrees. Refractory compounds from the second group (rubrax) are made according to the same scheme, but only with the addition of an alkaline component. When mixed with certain types of solvents, they form varnishes containing a percentage of components insoluble in benzene (no more than 0.15 percent).
The production of these substances takes a long time, which is required for complete oxidation of the oil residue. Another difficulty of this procedure is the low yield of pure bitumen per unit of investment.
Air blowing method
Another way to obtain purified bitumen is the oxidation of its initial components in air jets accelerated to high speed. At the same time, the temperature in the central part reaches 250-280 degrees with an air consumption of 1.76-2.5 liters per unit of product weight.
The total duration of the process, in this case, is twelve hours and is determined by the maximum softening temperature of bitumen.
The disadvantages of this approach include:
- long duration of the oxidation process;
- high temperatures to obtain the final product;
- small useful yield of material.
The quality of the resulting bitumen depends on the type of raw material used and does not always meet current standards.

How to dry a painted product
There are two schemes for drying products depending on the temperature of exposure to the surface. At a temperature of 20-22 degrees - 16 hours and at 100-110 degrees - 3 hours. If in the first case the varnish BT 177 dries in natural, domestic conditions, then when exposed to artificial heat, certain requirements must be observed. Before using hot drying, keep for half an hour at 22 degrees. Before use, the product must also be exposed to 18-22 degrees for 3 hours.

Preparing the base for painting
Metal surfaces must be freed from remnants of the old coating. You can use special chemical removers, sandpaper, or a sandblasting machine.
Traces of grease, oil and other stains and contaminants must also be removed.
Puttying and applying primer mixtures are carried out if necessary.

Bitumen paint: market analysis
Bituminous paint is a paint with a high content of bitumen - a viscous, sticky black compound. Bitumen is a petroleum product that looks like a resin and contains a large amount of hydrocarbons. It is produced by fractional distillation of oil and petroleum products. Crude oil is refined at temperatures between 300 and 350 degrees Celsius and then processed in a distillation unit.
During evaporation, light fractions of oil are separated. The higher boiling point fractions remaining in the distillation unit are processed in a vacuum distillation unit. The result of the distillation process in this plant is the production of tar, which is used to produce various types of bitumen paints. Applications for bituminous paint include anti-corrosion protective coating of steel, wood, concrete and other surfaces. The drying time of bitumen paint depends on its type, and usually varies from 6 to 24 hours. Previously, bitumen paint was mainly used as a waterproofing material for boats, but thanks to active research and development of this market, the field of application of the paint has expanded. The main industries that use bitumen paints are construction, aviation, shipping and furniture manufacturing.
As a rule, bituminous paints are supplied ready-made and do not require additional solvents or additives for subsequent use. To apply bitumen paint to the desired surface, regular brushes, sprayers or other traditional painting tools are used. Thus, bituminous paints are very easy to use, which is one of the main factors increasing the demand for this type of paint. Bituminous paints are used mainly for commercial purposes, in various fields of mechanical engineering, as well as in the production of water tanks, pipes, etc. For these reasons, the demand for bituminous paints is highly dependent on industrial investment in the region. Macroeconomic factors such as GDP growth are also one of the major drivers of asphalt paints market growth. The main raw materials required for the production of bitumen paints include crude oil and its derivatives.
