Abstract
The present disclosure relates to the field of anticorrosive pigments. Anticorrosive pigments are used with organic coatings to reduce the corrosion rate of the substrate metal. An anticorrosive pigment is incorporated in the topcoat of an anticorrosion coating system which greatly reduces the corrosion rate of the substrate metal in the environments of aggressive ions.
Claims18
A corrosion inhibiting coating composition for coating a metal substrate comprising a topcoat layer having a cation exchange pigment, and a primer layer.
A method of protecting a metal or metal containing substrate from corrosion, the method comprising coating the substrate with a topcoat layer having a cation exchange pigment.
