Technical characteristics and scope of primer-enamel ХВ-0278 Properties and application of the primer-enamel XB-0278

In order to increase the operational life of metal surfaces, and also to protect against rust and corrosion, various paints and varnishes are used.

Thanks to enamel and priming agent, the base will receive an increased level of resistance to negative environmental influences and adverse factors. One of the most effective and versatile materials will be the primer-enamel XB-0278, and its features make it possible to apply it to the surface of rust or even corrosion.

This primer will perfectly protect surfaces, improve wear resistance, and increase the service life of the metal in each climatic zone.

Primer-enamel and its description

A means of universal action, such as primer enamel, is a special type of primer that has additional characteristics of enamel, and it also helps to transform rust.

Such a tool was able to combine three functions at the same time.

Primer-enamel is not a novelty offered by the construction market, and such material has been made by the popular company Antokolor Paints and varnishes for more than 15 years. The primer is packaged in a container from 1 to 25 liters, and the cost of one liter of the primer is about 130 rubles.

The operational period of the product is approximately 5 years, and subject to the rules of preparation of painting and surface. There is a need, you can buy modern paints and varnishes, the service life is up to 15 years, but the cost of such compositions is much higher.

At the moment, the manufacturer makes the primer in different colors and shades, so you have the opportunity to choose one of these shades - yellow, blue, black, gray, blue and brown.

  • Painting steel, iron, cast iron structures and parts, even in areas with scale or carbon deposits.

  • Painting various types of structures that are large and complex shapes, for example, car parts. Metal garages, bars, fences, stairs and gates.
  • The primer can be applied to those types of structures that will not need a decorative type of design.
  • Treatment of bases to obtain a refractory layer.

Please note that in addition to being applied to metal structures, XB-0278 is suitable for processing concrete products and reinforced concrete structures, for example, fences, curbs or walls.

Enamel composition

The main chemical component of the primer-enamel is perchlorovinyl resin, and the composition should also contain several additional components. Such a resin is most often used for the manufacture of pipes and baths, and also often in contact with aggressive chemical substances, and also perchlorovinyl substance is used to create various paints and varnishes, which have protective characteristics against corrosion and rust.

In addition to this resin, the composition contains:

  • Epoxy and alkyd resin.
  • Coloring pigments to give the enamel the desired shade.
  • Substances by the type of plasticizers.

  • Chemical converters for rust.
  • Substances that prevent corrosion and metal oxidation (inhibitors).

Specifications

Enamel XB-0278 is made according to GOST, which contains all the technical characteristics, as well as the composition of this paint and varnish material. Any batch is accompanied by official certificates that confirm the high quality of the products.

The certificate must indicate certain properties of the primer, as well as the characteristics of the composition after it has been applied.

Here are the main properties of the primer enamel:

  1. The viscosity index according to the VZ-246 device or devices with a nozzle diameter of 0. 4 cm at room temperature is only 30 s for black enamel, and for other shades the viscosity is at least 40 s.
  2. The proportion of components for black paint will be from 34 to 44%, and for all other primer shades from 30 to 37%.
  3. The period of drying of the primer-enamel to the third degree is approximately one hour, provided that the temperature is + 20 .

    .. + 22 degrees.

  4. Consumption of funds for each square meter ranges from 0. 12 to 0.

    15 kg. The consumption rate will largely depend on the thickness of the rust, the methods of application and the characteristics of the material to be processed.

  5. The thickness of a single-layer enamel coating is from 20 to 25 microns (for the first layer), from 20 to 40 microns (for the second and third layers).
  6. Ideally, apply a couple of coats to the surface.
  7. The grinding index will be no more than 40 microns.

  8. The elasticity of the dried layer for bending will be a maximum of 0. 1 cm.
  9. The adhesion index is from 1 to 2 points.
  10. Hardness, according to the indications of the pendulum device, not less than 0. 15 units.

  11. Resistance to 3% sodium chloride for at least 3 days, provided that the temperature is +20 degrees.
  12. Coefficient of conversion efficiency of the rusty layer from 0.7.

After applying a layer of enamel, a homogeneous, matte and dense layer without foreign elements is obtained on the surface.

Application

Preparatory work for the base

Apply the primer on a properly prepared surface, which may be rusty.

If it is loose, it should be treated with a metal brush so that it begins to separate. Remnants of old paints and varnishes should be removed from the base, as well as any types of contamination, for example, scale, dust, dirt, grease stains using solvents.

Rules for the storage of enamel

Technical characteristics and scope of primer-enamel ХВ-0278 That the primer was as durable as possible and of high quality, you should know and follow all the rules for storing paints and varnishes. It can be transported by any means, and the temperature should be maximum +30 degrees. During transportation and storage, the container in which the enamel should be protected from the effects of precipitation.

The container must not be stored near a heating device or in a room with high air humidity. The room must be necessarily darkened from the rays of the sun, and the container with the enamel must be well closed. Primer-enamel for rust XB-0278 should be stored correctly, and it can be stored even in frost, at temperatures from -25 degrees to +30. Subject to these rules, the composition will not begin to lose its characteristics for a long time. The shelf life of the composition will be 1 year from the date of production.

How to dilute the primer

If the composition is too thick, then it will be diluted mono, and for this they use solvents such as R-4 and R-4A. Such solvents can be used to pre-treat and clean up contaminants. Compositions R-670 and R-670A can also be used for dilution. The manufacturer usually does not write how much solvent can be added, so the viscosity of the mixture can be checked during application.

If applied by roller or brush, enamel may be more viscous than when sprayed from a spray bottle.

When diluting, add the solvent in small portions, and after each of them, the mixture must be thoroughly mixed. When the composition is applied to the surface of the base, the solvent will begin to quickly evaporate, and the film will become strong after drying.

Please note that each solvent is harmful and toxic to humans, and therefore, when working with primer-enamel that has been diluted with solvent, a respirator, rubber gloves and protective heavy clothing should be worn. When working indoors, ensure good ventilation or ventilation.

Rules for painting

It is possible to apply the primer-enamel using the following methods:

  • With a brush.

  • Roller.
  • Spray from a spray gun or spray bottle.
  • By dipping (suitable for small parts).

When applying the product, its temperature should be from -10 to +30 degrees, and the air humidity level should be from 55 to 80%. The first layer to be applied will dry in about 1-2 hours, provided that there is room temperature, and all further layers can be applied 1 hour after the first coat.

To make the film strong and durable, it is recommended to apply the product in 2-3 layers. When applying the first layer, rust will transform, the second layer will become anti-corrosion, and the third will play a decorative role.

The most popular mistakes

When using primer enamel, the following erroneous actions should be avoided:

  1. Do not apply just one coat. Sometimes someone wants to save a solution, and therefore they process metal structures in only one layer. Such a coating is not of good quality, because the primer will simply soak into rust or corrosion.

    Apply the composition in 2-3 layers strictly according to the instructions.

  2. Do not use dry spray. This method is most suitable only when a competent specialist works with correctly configured devices. If a beginner is to paint using a dry spray method, the adhesion and stability of the protective layer will be minimal.
  3. Use an unsuitable thinner for dilution.

    It is allowed to use only those funds that are prescribed in the instructions. All other compounds are ways to violate the characteristics of the enamel, and it will dry out for a very long time. Do not mix the primer with white spirit.

  4. Not allowed before the time of using the product. It is important to wait for the painted coating to fully cure, as otherwise the quality of the protective layer will be reduced.

  5. Do not apply product to smooth parts. For a good adhesion rate, the substrate should not be perfectly smooth, but rough. The primer is made specifically for application on uneven and rusty surfaces. If the base is smooth, then you should first process it with sandpaper, make it rough, and only then paint it.

By following the recommendations and applying the primer-enamel according to the instructions, the metal part or structure will be well protected.
