Acid resistant paint for processing - features

Acid resistant paint for processing - features Acid-resistant paint for walls and metal - properties, types

In order to protect some surfaces from aggressive external environments, paints with special characteristics are required. Such paints and varnishes should not be destroyed by acids or other chemically active agents. Acid resistant paint can be one of those highly resistant materials used for surface treatment that are extremely important.

There are many varieties of acid resistant paints and varnishes on the market. Paints differ from each other in composition, but the preparation work in all cases is unchanged and can only differ depending on the type of coating.

The most famous acid-resistant paint and varnish material is XB-785. The paint has been produced since the time of the USSR. It is with this composition that a huge part of the surfaces that are used in an aggressive environment is painted.

Characteristics of anti-acid paintwork materials

Please note that all technical requirements for acid-resistant paint and varnish materials are set out in such a document as GOST 7313-75.

Acid-resistant compositions have the following characteristics:

  1. The basis of this type of paint and varnish material is a mixture of two types of resins - polyvinyl chloride and alkyd.

    Such components are diluted with organic solvents. In the role of additives, pigmenting agents are used, and also plasticizers - they will improve the characteristics of the material, and also increase the resistance of protective coatings in the external environment.

  2. The ready-made solution is intended for use only as part of a complex protective coating. In other words, if unprepared surfaces are painted with such paint, the manufacturer refuses to guarantee the preservation of the declared commercial properties.
  3. The acid-resistant composition can be used for painting a wide variety of materials, including concrete, metals, and plastered surfaces.

    The paint and varnish material is used both for painting the interior of buildings and for facades.

  4. When the painted surface dries up and it receives all the characteristics specified by the manufacturer. But it is worth considering that anti-acid paints and varnishes lose their qualities at temperatures above +60 degrees Celsius.
  5. Acid resistant products should only be applied by spraying. Rollers and brushes are not used for working with such paint.

Now about the priming process.

Details

Priming with varnish

Before painting the surface , it should be primed for XB-785 paint; XB-784 varnish composition is used as a primer. The characteristics of such a varnish, as well as its quality parameters, are determined by the provisions of GOST 7313-75.The use of a primer varnish composition makes it possible to strengthen the base, and also achieve ideal adhesive properties of the coating. It is the priming that will ensure the reliability of the protective coating and make it possible to add its service life.

Two-component products

Recently, two-component products, which combine epoxy paints and hydrocarbon resins, have become increasingly popular. For paints of this type, the following qualities are characteristic:

  1. Acid resistant paint for processing - features Components of acid-resistant paint for battery rooms are offered by separately, and therefore they should be mixed before staining. In this case, it is required to achieve complete uniformity of the composition, since the properties of the coating will be much worse than they could. It is recommended to mix the components with a drill with a mixer installed on it. It is better to stir the composition at low speed so as not to start splashing the liquid.

  2. Two-component products can be applied not just with a spray, but also with a roller and a brush. The choice of a specific surface treatment method will be dictated by the tasks and the amount of paint.
  3. Apply a paint-and-lacquer-type compound using protective equipment. You will need a respirator, gown and gloves. If you do not think about safety, paint and varnish material that gets on the skin can cause allergies or irritation.

  4. Approximately 24 hours after painting, the coating will dry and will be ready for use in adverse outdoor conditions.

Please note that surfaces painted with anti-acid paints can be washed with detergents. This will not damage the base or change its performance.

Features of the work

When performing work, a number of rules should be followed:

  • Acid-resistant paints for wall surfaces, do not dilute with extraneous ingredients. This will adversely affect the quality of the coating.

  • His weather forecast will report rain, work should be canceled. According to technological requirements, drying of the surface must necessarily occur without direct contact with water.
  • It is only necessary to paint on a dry surface.
  • The substrate should never be dirty, and it is required to remove dust, debris and oil stains from it.
  • The surface must not be loose.

    If so, it is required either to refuse staining, or to take measures to create a surface that will be much denser.

  • Painting works can be performed only in the recommended temperature regime - the maximum temperature is +30 degrees, and the minimum is +5 degrees.

Work is carried out in this order:

  • The first step is to remove dirt from the surface.
  • If the substrate is wet, dry it.If necessary, you can use a heat gun or a building hair dryer.

  • Painting is carried out in two coats, and this is the minimum requirement, because in certain cases three to four coats of paint may be required.

Let us consider separately the paint "AnticorChem".

Acid-resistant alkali-resistant paint "AnticorChem"

On the market there is not just XB-785, but also other types of anti-acid compositions. One of them will be acid-resistant paint "AnticorChem", and as an example it is worth examining the characteristics of the specified paint and varnish material, as well as the features of its use

. "AnticorChem" as an acid-resistant paint, is used for painting the following types of surfaces:

  1. Acid resistant paint for processing - features Baths from metal structures, technological equipment that come into contact with alkaline and acidic media during operation.

  2. Tanks for storage and transportation of oil products, alcohols and acids.
  3. Marine vessels, as well as hydraulic structures.
  4. Metal piles and piers.
  5. Metal structures that operate under increased load (handrails, steps, platforms, etc.).

Advantages of the AnticorChem paint and varnish material:

  • Resistance to aggressive external environments. The paint is specially adapted for use in harsh conditions. A distinctive feature of "AntikorChem" is a higher temperature threshold compared to competitors - the coating will not lose its quality at temperatures up to +70 degrees.
  • Speed ​​of drying and relatively low requirements for preparation work. The paint and varnish material dries out within an hour, and it can be applied even on rusty surfaces.

  • Versatility of use. The product has excellent adhesion characteristics in relation not only to rough steels, but also to galvanized and non-ferrous metals.

Paints for metal, which are resistant to aggressive environments, as well as other materials - they are irreplaceable in construction and industry. Anti-acid agents place high demands on the process compliance. For this reason, carefully read the instructions from the manufacturer before using such paints and varnishes.
