ZINC RICH COATINGS
Zinc Rich coatings normally contains 92-95% metallic Zinc in the dried film
which imparts high protection to steel structures. On ferrous metals this is used
as Cold Galvanizing purposes. Before application the surface should be neatly
made free from grease or oily matters. Surfaces with Zinc Rich coating should
be over coated with similar paint system e.g. Epoxy Zinc Rich Primer should be
over coated with Epilux 4 Enamel.
ZINC SPRAYED STEEL
As an anti-corrosive measure steel is coated with metallic Zinc. Unlike
galvanized iron, Zinc sprayed surface is porous. However, for better adhesion
Wash Primer should be used for over coating with a finish paint epoxy and
chlorinated rubber, etc.
