| AST MS-7CZ RUST INHIBITIVE PRIMER is a lead and chromate free, rust inhibitive, two-component, epoxy primer specifically designed for use in conjunction with ITW Performance Polymers’ coatings applied to metal substrates. It meets USDA standards for maintenance protective coatings not in direct contact with food in federally inspected meat and poultry plants. AST MS-7CZ RUST INHIBITIVE PRIMER is recommended for use as a metal primer in severe industrial and chemical environments. It possesses excellent adhesion to properly prepared iron and steel surfaces, providing rust resistance to ferrous substrates, both on initial application and in the event of damage to the topcoat. It can be used under many epoxy, urethane, vinyl, chlorinated rubber and coal tar/ epoxy finish coats. The 7CZ Primer contains a new, state-of-the-art compound that was created by combining zinc and phosphate at the molecular level. Zinc complexed with phosphate becomes a non-metallic compound that is completely different, from regular, inorganic zinc. Inorganic zinc primers are made from ground metallic zinc powder mixed with a very basic inorganic polymeric liquid. Rust Inhibitive 7CZ Primer, on the other hand, is made up of a very high quality, 2-component, polyamide epoxy and a small amount of zinc complexed with phosphate. Rather than metallic zinc, the 7CZ Primer has very good anticorrosion properties and promotes adhesion of steel to epoxy grout.Information provided by ITW Performance Polymers. |
