Zinc Rich Primers

Our zinc-rich primers offer superior long-term protection for steel from corrosion. They perform similarly to galvanizing. They contain a high percentage of zinc dust, which acts sacrificially when in direct contact with the steel. The zinc salts, which invariably form, fill the pores of the primer sealing off the steel substrate from moisture.

Organic Zinc Rich Primer

Zinc Organic Epoxy is the primer of choice in highly corrosive environments. This product was formulated to withstand many different environments, when topcoated with Sumter Coatings high quality topcoats. We can guarantee a high performance system whether you choose an epoxy or urethane topcoat.

Inorganic Zinc Rich Primer

Our inorganic zinc-rich primer may be used as a single coat for weathering protection, or be applied as a primer for subsequent application of organic topcoats. It has high zinc content to provide steel with protection of undercoating. Enviro-Zinc 97 is self-curing and has good application characteristics. Two dry mils of this primer are resistant to rain and water after one hour cure. Develops film integrity quickly and may be topcoated after overnight drying at relative humidity of 50%, or greater. Longer cure times are needed at lower relativity humidity.
