MCU-100
A one component moisture cured polyurethane aluminum coating. Has excellent adhesion to sound, tightly adherent rusty steel, and other marginally prepared surfaces. This low viscosity, high “wetting” coating undergoes a rapid molecular weight change as it polymerizes into a high molecular weight finish which provides excellent corrosion resistance and abrasion resistance. Its resistance to creeping, undercutting, and blistering is superior to epoxy primers. MCU-100 is also a barrier primer or tie coat to prevent lifting of strong solvent top coats being applied over conventional coatings, and over most existing chemical coatings. Excellent as a universal primer for metal, steel, concrete, wood, fiberglass, plastic, clean or weathered galvanized metal. Also over old coatings and for polyurethane foam protection. For use over sound, tightly adherent rusty steel where only wire brush or hand tool cleaning is feasible. For remedial painting of fences, metal buildings, hand and guard rails,
