M-1 CR (Clean Room) is a thermosetting, moisture cure sealant which does not contain solvent or isocyanates. M-1 CR has been tested for airborne molecular contamination and is approved for semiconductor clean room use. Fully cured M-1 Clean Room Sealant releases virtually no molecular air contamination at room temperature. M-1 CR is specified for biomedical, electronics, and aerospace clean rooms where contamination of the air and working surfaces cannot be tolerated. M-1 CR also used in food processing, hospitals, schools, offices and public buildings.
M-1 Marine is a moisture cure adhesive/sealant formulated for applications above or, post cure, below the water line. M-1 Marine is free of solvents, phthalates and isocyanates, will not shrink upon curing or discolor from ultraviolet exposure, and will not bubble on damp surfaces. It adheres to many surfaces usually without priming including teak, fiberglass, vinyl, glass, FRP and metal, forming a strong bond, yet remaining resilient and flexible after cure. It can be applied in wet or dry climates and at temperatures as low as 32°F (0°C).
