Indurazinc MC67 is a single component, moisture-cured, aromatic urethane, organic zinc-rich primer. It provides superior galvanic protection in outdoor ambient conditions but is also Classified by UL to NSF/ANSI International 61 for potable water immersion service in tanks of 5,000 gallons and greater capacity. This product provides galvanic protection for carbon steel substrates with dried films that contain 83% zinc by weight. Indurazinc MC67 has the durability, toughness, and adhesion of a densely cross-linked polyurethane binder to provide outstanding long-term corrosion protection. Quick cure, same day recoat, and unlimited recoat time allow for efficient shop and field priming and recoating.
