M-1 Marine Grade Sealant is a moisture cure polyether adhesive sealant formulated for applications above the water line or after curing below the water line, and in areas where solvent based materials are not tolerated. The product is solvent free and contains no isocyanates. It will not shrink upon curing, will not discolor when exposed to ultra violet light, and will not out-gas or bubble on damp surfaces as urethane sealants often do. The sealant has resilient elastomeric properties and excellent adhesion to most substrates. It can be used effectively in many difficult conditions, cures rapidly in wet or dry climates, and low temperatures compared to urethane based materials. M1- Marine Grade waterproof sealant creates tough elastomeric bonds with fiberglass, wood, teak deck planking, Gelcoat, Polycarbonates, Stern Joints, Moldings, Deck Fittings, Portlights, Struts & planking, glass, star board, metal, and most plastics. It is fast setting, and paintable in 24 hours. 100% VOC Compliant.
