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, pumps, pipelines, grating, and other hard to clean surfaces.

Ideal as a barrier coat over lead based coatings and conventional coatings. The low solvency power of MCU-100 enables it to be applied over most type coatings without causing lifting. A test sample should be made to confirm adhesion. Most generic types of chemical or conventional coatings may be applied over MCU-100 with excellent adhesion.

Has excellent chemical resistance as a Finish Coat to protect metal, concrete and wood surfaces in chemical plants, refineries, pulp and paper mills, waste and water treatment plants, electric generating stations, fertilizer plants, food processing, pharmaceutical, ore processing operations, marine installations to name a few.
