Dyno Epoxy Zinc Rich Primer P-4300 Description : A two-pack organic zinc rich polyamide-cured primer for the steel in which the ultimate protection against corrosion is required. The rich zinc dust forms a continuous layer on the metal substrate and thus simulates the action of the galvanized zinc which provides the cathodic protection through the sacrificial action of the zinc dust. The fully cured film is non-toxic and offers maximum corrosion protection in the severe industrial or marine environment. Ideal to be used as protective metal primer for the maximum corrosion protection for the clean steel or abrasive blasted steel structures in the severe industrial or marine environment.
