PennCoat’s Paint Failure Series – Fading


Paint Fading – Causes

There are various types of industrial paint.  But typically, all these paints work in the same system: 1st coat is the primer, 2nd coat is the intermediate coat, and the 3rd coat is the top coat.  The primer has anti-corrosive pigments that helps prevent corrosion and promotes surface adhesion for next layer of paint.  A layer of intermediate coat helps to increase the thickness of the paint without applying a very thick finishing coat.

Each layer of paint has its own specific function and adds to the durability of the product. Top coatings on products provide protective layer against corrosion, abrasion, chemical resistance and also adds to their aesthetic properties. But, if the top coat has not been applied properly, it can deteriorate the appearance of the product rather than adding to it.
