Composition of water-based paint
Water-based paint is one of the types of paint and varnish material that has a high level of density. It belongs to the category of durable decorative coatings for various types of surfaces.
This type of dye is produced in huge quantities. For different types of surfaces, you can choose the best option.
Water-based paints can have different compositions. Basically, such a coloring matter contains a large mixture of polymer compositions and water. Such paints may contain additional substances that allow manufacturers to produce paint products of this type with certain physical properties.
Water-based paints may contain:
- thickeners,
- antiseptics,
- plasticizers,
- antifreeze,
- defoamers.
Depending on the brand of paint, certain substances are added to it to make it suitable for use on various types of coatings.
The proportions of the components used depend on what this or that type of paint and varnish product will be used in the future. Initially, all water-based paints are white. For this purpose, special pigments are introduced into them. In some cases, in order to save money, manufacturers add regular chalk to obtain a rich white shade. All substances that make up the paint are usually diluted with clean water.
This type of paint and varnish product has a large number of features and advantages.
The advantages of water-based paints are:
- no unpleasant pungent odor,
- quick drying after application to the surface,
- the ability to acquire the color that is needed in certain conditions. You can add different pigments to the paint to create the optimal shade.
- ease of application.
Attention:
This type of paint and varnish material has one drawback, which is that it must be applied to the surface only at a temperature of five degrees Celsius.
Today, the following types of water-based paints are distinguished:
- acrylic paints. The main component in the composition is acrylic resins.
- Silicone paints. They have a thicker consistency and contain more silicones.
- Silicate paints. It is universal and suitable for all mineral surfaces.
- Mineral paints. These paints contain lime or cement.

One of the most widely used methods of protecting various materials, products and structures from corrosion under the influence of the atmosphere and industrial gas-air environments is the creation of a protective paint coating on their surface.
At the same time, paint and varnish materials (paint and varnish materials) of environmentally friendly technologies are of particular interest, which include, first of all, water-dispersion paints. They have undeniable advantages: the complete absence of toxic and flammable solvents, which determines their environmental value, fire and explosion safety of production and application processes; low curing temperature of the coating; waste-free production; affordable price.
Water-dispersed polymer phosphate paints VD-KCH-1F based on butadiene styrene film-forming agents, produced by POLIFAN-L LLC according to TU 2316-00134895698-96, belong to such materials and fully possess the listed advantages [1].
Their distinctive feature is the presence of orthophosphoric acid in combination with its salts, which provides:
- transformation of iron oxides that form a layer of rust on a steel surface into a layer of iron phosphates tightly bonded to the unoxidized metal;
- high adhesion of the coating due to chemical interaction with the surface to be painted;
- imparting biocidal properties to the coating.
Coatings formed by VD-KCh-1F paints are stable at temperatures from -60 to +80°C in aggressive environments without humidity restrictions.
In terms of their characteristics, the coatings formed by VD-KCh-1F paints are not inferior to those formed by traditional coatings, such as oil-based, pentaphthalic, acrylic, glyphthalic, etc., and often surpass them.

According to the degree of impact on the body, according to GOST 12.1.007 they belong to the 3rd hazard class (moderately hazardous substances).
VD-KCh-1F paints are available in two grades: VD-KCh-1FA - for protection against corrosion of metal (carbon steel, cast iron, aluminum and its alloys) and grade VD-KCh-1FO - for painting facades (external surfaces) of buildings and structures for various purposes, as well as for finishing the interiors of residential, public and industrial premises.
VD-KCh-1FA paint can be used both as a primer in combination with traditional paints and varnishes, and for final finishing.
For metal structures operating in highly aggressive environments, combined coatings are used: VD-KCh-1FA paints are used as a primer, covered with chemical-resistant enamels such as HV, XS or varnishes. They are used for protective and decorative painting of metal structures for a wide variety of purposes (mechanical engineering products, building structures, bridges, sea and river vessels, railway and metro cars, bus bodies, etc.).
In terms of its protective characteristics (coating water resistance, corrosion resistance at high humidity and temperature and with additional exposure to a 3% sodium chloride solution), it is 1.5-2 times superior to the well-known Unikor-2 primer (formerly VD-KCH-0251 ) TU 2316-058-05034239-94 and paint VD-KCh-124 (formerly VD-KCH-0586) TU 2316090-05744283-93.
Color - red-brown, black, green.
The optimal coating thickness of 80-110 microns is achieved with a two-layer paint application and a consumption of 150-180 g/m2.
It is approved by sanitary and epidemiological authorities for coating the internal surfaces of drinking water supply pipes and tanks.
VD-KCh-1FO paint is intended for weather protection of structures made of reinforced concrete/concrete, slate, brick, cinder blocks, wood-based materials, etc. It is recommended for painting facades and interiors of residential, civil, industrial and agricultural purposes, as well as asbestos-cement materials ( slate), wood-based materials (chipboard, fiberboard, fiberboard), hardboard. Painting of aluminum and alloys is allowed.
The coating formed by VD-KCh-1FO paint has high performance properties: they are weather-resistant, withstand alternating temperatures for a long time, and have vapor permeability; crack resistance - 0.15-0.25 mm; adhesion to concrete - above 2.5 MPa. Painting increases the frost resistance and frost-salt resistance of concrete/reinforced concrete by more than 2 times, and reduces water absorption by 30-40%. The duration of the protective effect of the concrete layer for reinforced concrete reinforcement increases by 6–8 times [2].
A variety of pigments, both mineral and organic, provide a wide range of colors for VD-KCh-1FO paints. The introduction of fillers of varying dispersion (1-5 mm) into the paint formulation makes it possible to obtain coatings with a relief structure.
The use of acrylate and styrene acrylate film-forming paints in the formulations of VD-KCh-1F paints instead of styrene butadiene significantly increases the performance characteristics of the resulting coatings, eliminating their yellowing, increasing hardness, gloss, and increasing heat resistance (up to 120 ° C and above).
VD-KCh-1F paints are applied by pneumatic and airless spraying (using various types of apparatus), as well as by dipping, brush, and roller. The surface to be painted must be cleaned of dirt, including old peeling paint, and dried. It is recommended to carry out painting work at an ambient temperature of no lower than 15°C and a relative humidity of no higher than 80%.
For practical use, good compatibility of VD-KCh-1F paints with other paints and varnishes, both as a primer and as a covering layer for final finishing, is very important. Even old, non-flaking paint and traces of corrosion on a steel surface when using VD-KCh-1FA paint do not reduce the quality of the resulting coating.
VD-KCh-1F paints have been successfully tested at the Mosstroy Research Institute, the Reinforced Concrete Research Institute, the Central Research Institute of Building Structures, the Spektr LK Research and Production Association, the Paintwork Research Institute with OMZ Victoria, the All-Russian Research Institute of Railway Transport, the Central Research Institute of the Marine Fleet, as well as in the sanitary and epidemiological inspection authorities.
Tests carried out at NIIZhB showed that the protective and decorative coating formed by VD-KCH-1F paints provides reliable and long-term protection of concrete and reinforced concrete structures and structures from the effects of aggressive gas-humid and liquid environments at temperatures from -60 to +80 ° C.
Research carried out at the Research Institute of Paintwork (Khotkovo) commissioned by JSC BelATSI showed that VD-KCh-1F paints form durable, colorful, light-resistant, high-adhesive coatings on slate.
Factories in Voskresensk, Belgorod, Mordovia, Bashkortostan, Transbaikalia used and still use VD-KCH-1F paints for painting slate, thereby improving and significantly increasing its service life.

Features of the material
Before purchasing, you need to study some basic indicators of this composition:
- Viscosity is a characteristic of a substance, which is determined by the degree of concentration of water in the paint. The indicator is measured with a viscometer. To use a roller or brush, the viscosity should be 40–45 St. If the composition is applied using a spray gun, then no more than 25 Art.
- As for consumption, we can’t say for sure. The average is 180 ml per square meter. But this amount may vary depending on the characteristics of the surface being treated, the tools used and the quality of the paint. The specific gravity of the material is 1.4 kg/l.
The consumption of any paint during the first application is approximately 30% higher than during subsequent applications. - Drying time ranges from 2 hours to a day. This difference is explained by the fact that in damp rooms and without proper ventilation, water evaporates less intensely. The recommended operating temperature is 20 degrees Celsius and air humidity is 70%.
- The shelf life of water-based paints is limited to 24 months from the date of production. Once opened, the paint should be stored in a cool, dark place and should not be allowed to freeze.
