Silicone Zinc Copolymer
A high-performance, two-component, zinc-rich, silicone copolymer that offers galvanic protection to steel substrates for extended corrosion protection up to 1000°F (538°C). An excellent primer for use with selected topcoats as part of a corrosion- and heat-resistant coating system. Requires an exceptionally low minimum 250°F (121°C) heat cure prior to placing in service.
Series 1505 uses a zinc pigment which meets the requirements of ASTM D 520 Type III and contains less than .002% lead.
