Anti -corrosion paints are specialized protective coatings that prevent rust on metal surfaces. They are used in various industries, from heavy industry to home use, where metal constructions are exposed to moisture, salt or chemicals.
Anti -corrosion paints work by creating a protective barrier between metal and external factors such as oxygen, moisture and chemical pollution. Depending on the composition, they can:
Anti -corrosion paints are widely used in:
These are one of the most commonly used anti -corrosive paints. They are characterized by good adhesion to the ground and resistance to weather conditions, e.g. telryd S200 , i.e. primer alkyd dyed in accordance with the RAL palette .
Paints with very high chemical and mechanical resistance. Used mainly in industry and on surfaces requiring long -term protection. Neopox® Primer 815 or Telpox P100 is often used . They provide excellent anti -corrosion protection of the substrate, and also create adequate grip conditions for subsequent layers of systems.
They provide permanent protection and aesthetic finish. Often used as a top surface in protective systems, although they can also be used as undercoat paints as well as primers. An example of a polyurethane anti -corrosion foundation is Krypton Proline PU al Primer Krypton Proline Silver TC Krypton Paints , and Gruntoemalia Telpur S210 .
They contain zinc particles that act as an anode, preventing corrosion at the electrochemical level. Used mainly in heavy industry and steel structures. Cold galvanists in the form of paint or spray are often found, e.g. Galva Zinc or Galva Zinc Spray .
Before painting, thoroughly clean the metal of rust, dust and fat. This can be done mechanically (grinding, sandblasting) or chemically (degreasing preparations and rust -right).
If there is rust on the metal surface, it should be removed with a wire brush, sandpaper or a special chemical. You can also use rust converters that transform visible rust into a less reactive form. Top-kor is used for this-only for solvent products and Neodur® Metal Force for both water and solvent products.
The metal must be degreased so that the paint adheres well. For this purpose, you can use solvents or dedicated preparations such as Sulfanol A or Emulsol .
For additional protection, it is worth applying a special anti -corrosive foundation that increases the paint's grip and strengthens its protective effect. Epoxy anti -corrosion soils such as Neopox® Primer 815 .
Anti -corrosion paints can be applied in several ways:
Before painting, mix the paint thoroughly and follow the manufacturer's recommendations regarding temperature and application conditions.
Polyurethane anti-corrosion aluminum paint for steel, metal or concrete. Can be applied at low temperatures (-18°C) and high humidity (up to 99%) - practically at any time of the year, regardless of weather conditions. For anti-corrosion protection and painting of bridges, steel structures, roofs, steel pipes, etc.
Primer for epoxy, acrylic and polyurethane topcoats. Durable in changing weather conditions, constant contact with water and industrial atmosphere. Provides anti-corrosion protection and excellent adhesion.
Epoxy primer for steel. It protects against corrosion and has high chemical resistance.
One-component primer enamel protecting against rust in environments with corrosivity class up to C3. Many color versions.
Fast-drying industrial primer enamel. Available in many colors, does not require priming and contains anti-corrosion pigments.
Anti-corrosion coating with 90% zinc content in dry film. Provides cathodic protection. For use on new or very well cleaned steel substrates.
Cold galvanizing product, quick-drying. For use on new or cleaned steel surfaces. Product based on polyhydroxyether resin.
A primer that protects surfaces against rust in corrosion class C3 to CX. Possibility of application even on rust residues. Contains aluminum pigments.
Concentrated agent for degreasing surfaces before painting. Mainly recommended for use before painting with anti-corrosion products.
For cleaning concrete, roof tiles and metal before applying paint coatings. Requires rinsing with water.
The choice of the best anti -corrosion paint depends on the operating conditions. Alkyd and polyvinyl paints are often chosen for home use, while zinc, polyurethane or epoxy paints dominate in industry.
The durability of the paint depends on its type and the conditions in which it is used. There are different classes of corrosion environment, as well as various periods of durability, for which the coating thickness and the type of paint are selected. The shortest durability period is up to 7 years and requires the thinnest layers of paint compared to the other periods of the coating strength.
Some anti -corrosion paints are adapted to the application directly to rust, but for better durability it is always recommended to clean the surface.
Anti -corrosion paints are an effective way to protect metal against rust. Choosing the right type and proper surface preparation will ensure long -term protection and aesthetic appearance of metal structures.
