Description
Tectyl 185GW Black is a premium solvent-based gelled calcium sulfonate corrosion preventive compound manufactured by Daubert Chemical Company. This advanced undercoating is cut back with mineral spirits and specifically designed to provide exceptional, long-term protection for components exposed to harsh marine, tropical, and industrial environments. When applied, Tectyl 185GW Black forms a semi-firm, black wax-like film that repels water more readily than asphalt-based coatings, offers self-healing properties when disrupted by minor damage, and maintains flexibility even at low temperatures, ensuring continuous protection for transportation equipment, industrial machinery, and metal structures exposed to corrosive environments.
