Zinc Rich Epoxy Primer

Zinc Rich Epoxy Primers are available in organic (epoxy-based) and inorganic types, with organic epoxy zinc primers being the most widely used in industrial coating systems. They are applied on properly prepared steel surfaces (typically Sa 2½ blasting) and are suitable for steel structures, pipelines, storage tanks, offshore platforms, bridges, refineries, power plants, and marine equipment. Key advantages include excellent corrosion resistance, strong adhesion to steel, compatibility with epoxy, polyurethane, and polysiloxane topcoats, and high resistance to moisture, chemicals, and mechanical stress. Typical properties include high zinc content (often >80% by weight in dry film), fast curing, good weldability, and long service life in C3 to C5 corrosion environments.
