SURFACE COATING AS PROTECTION AGAINST CORROSIONYou can choose one of three different types of surface treatments; painting, coating or linings as a means of protection against corrosion.
Painting and Coating
A painted surface usually has a thickness of up to 0.15 mm. A coated surface can be applied if this is not sufficient to protect against corrosion resulting from chemical splashes or a corrosive atmosphere etc. This type of surface coating usually has a layer thickness of between 0.3 to 0.7 mm.
It is economically viable to apply linings where chemical stress or mechanical abrasion is of a magnitude that neither paint nor coatings are adequate for the protection of the metal structures etc. This is usually a protective layer of between 3 to 6 mm in thickness.
