Supermarine Zinc Chromate Primer (SM-1184) is a premium-grade, high solid marine primer that not only acts as an effective rust preventative on steel and iron substrates but should be viewed as an integral component of a corrosion resistant coating system on metal in a marine environment. It is a rust-inhibiting Red Oxide Primer that is easy to spray and fast-setting.
Zinc Chromate Primer is based on a zinc chromate-ferric oxide anti-corrosion marine coating system. This highly effective zinc primer binds rust to metal sealing out rust causing air and moisture. It is intended for use as a protective metal primer for new or rusted surfaces. It is zinc rich and contains a balanced composition of special pigments and phenolic modified resin providing good rust-inhibitive properties and blister resistance for better adhesion and metal protection.
Designed primarily as a corrosion-inhibiting zinc primer for use on steel and aluminum vessels, equipment, machinery, ferrous and nonferrous metal surfaces before a top coating system is applied. Supplied at a spray viscosity designed for airless use. Satisfactory for application in a wide range of temperatures or humidity conditions.
Designed for spray application over surface-treated metal or pretreatment marine primer (See SM-117 Pre-Treatment Wash Primer). Color: Red Oxide.
