Description
Tectyl 185GW Gray is a premium solvent-based gelled calcium sulfonate corrosion preventive compound manufactured by Daubert Chemical Company. This advanced undercoating is designed to provide superior abrasion resistance, weathering, and corrosion protection in demanding marine, tropical, and industrial environments. When applied, Tectyl 185GW Gray forms a non-tacky, wax-like film that is semi-firm yet flexible, repels water, offers self-healing properties, and maintains flexibility even at low temperatures. The distinctive gray color provides added visibility, making it easily identifiable during equipment inspections and ensuring proper coverage on both new and used surfaces.
