What is anti-corrosion coating? Protective Coating In Kuwait 2024

In construction, industry, agriculture and other industries, metal structures, metal equipment, steel pipelines, etc. are widely used. The metal has high strength and reliability; modern technologies for its processing make it possible to obtain products and structural elements of any required shape with specified characteristics.

However, the main problem with using metal is its susceptibility to corrosion. Therefore, effective anti-corrosion protection is of great importance for the durability of metal structures and equipment.

How to protect the metal from corrosion?

Protection methods can be divided into three groups based on the principle of their influence on changing the course of the corrosion process:

  • Changing the properties of the metal (alloying, heat treatment, etc.);
  • Changing the properties of the medium (medium inhibition, air drying, etc.);
  • Changing the nature of the interaction between the metal and the medium at the interface (application of paints and varnishes, cathodic polarization, etc.).

The most widely used, universal, inexpensive and convenient method is the application of anti-corrosion coatings to metal structures, equipment and structures. Modern anti-corrosion protective coatings provide a high degree of protection and are durable and resistant to external factors. In addition, along with protection, they give the painted surfaces decent decorative properties.

How does the protection of anti-corrosion coating systems work?

Anti-corrosion coating systems are usually systems consisting of a primer and a finishing (top) coat. First, a primer layer is applied to the previously cleaned and treated surface. The primer has high adhesion to metal and has the main function in the system - protection against corrosion. Finishing enamels (acrylic, polyurethane, etc.) are used as a coating layer.

Primer coatings are divided into five main groups:

  • insulating (based on inert pigments)
  • passivating (creating passive layers on the metal surface)
  • phosphating (formation of a phosphate film on the metal surface)
  • Protective (contains metal particles that act as a consumable anode. Zinc powder is most often used as such a pigment.
  • rust modifiers (contains special corrosion inhibitors that convert rust into a stable compound)

Which anti-corrosion coating to choose in Kuwait?

Here are some popular anti-corrosion coating options, along with their pros and cons:

  • Corrocoat is a leading brand of high-performance anti-corrosion coatings, offering a wide range of solutions for various industrial and marine applications.
  • Epoxy: Excellent adhesion, chemical resistance, and heat tolerance. Can be brittle and require multiple coats.
  • Polyurethane: Durable, flexible, and UV-resistant. More expensive than epoxy and may require specialized applicators.
  • Acrylic: Affordable, UV-resistant, and easy to apply. May not offer the same level of protection as epoxy or polyurethane.
  • Fluoropolymer: Exceptional chemical and heat resistance, UV-resistant, and self-cleaning. Very expensive and requires specialized application.
  • Vinyl ester: Good chemical and saltwater resistance, affordable. Not as UV-resistant as epoxy or polyurethane.
