What is corrosion protection coating?

Corrosion is the physico-chemical reaction of metal when it interacts with its environment.

As a result of corrosion, rust forms. When we talk about corrosion protection coating, it means creating a protective layer to prevent rust formation on steel or iron.

Corrosion protection coating is effective

Painting a metal surface is the most effective method for corrosion prevention. A dense, intact, and sufficiently thick layer of paint prevents ions from penetrating the metal surface, thereby reducing the formation of local electrochemical cells. Corrosion can be prevented by using corrosion-protective paints containing corrosion-inhibiting pigments, as well as by applying a sufficiently large cathodic protection layer onto the surface of steel or iron.

Planning and choosing the right technical solution

Painting a metal base is called corrosion protection coating and serves to protect the metal base from destructive environmental influences. The most common methods for corrosion protection coating are spray painting and powder coating. Spray painting is often used for heavy workpieces, while powder coating is popular for sheet metal products, for example.

When planning corrosion protection coating, various factors must be considered: the structure, function, and lifespan of the component; environmental conditions and specific stresses; design and construction; surface cleaning and pretreatment; choice of paint; coating location; timing and environmental conditions; quality control of painting work; as well as options for maintenance painting.
