Zinky-12 Inorganic Zinc Rich Primer 77 is a two-pack, solvent-based coating composed of ethyl silicate and zinc dust. It is suitable for use on steel as a primer for high performance systems and as a single treatment coating for a variety of marine environment. It prevents corrosion and provides excellent resistance to weathering, abrasion, impact, heat and many solvents.
The level of zinc dust by weight present in the dried film conforms to SSPC-Paint 20 (Level 2). The type of zinc dust used complies with ASTM D 520 (Type II). It has been tested for Slip Coefficient and Creep Resistance, using ASTM A490 bolts and meets Class B requirements by RCSC Specification for Structural Joints Using High-Strength Bolts (Appendix A).
