M-Thane™ One-Part Pourable Sealant

M-Thane™ One-Part Pourable Sealant is a moisture cure, self-leveling sealant that is suitable for application in damp and cold climates, as well as dry climates. M-Thane™ One-Part is solvent-free, contains no isocyanates, and will not shrink upon curing. It does not “outgas” or bubble on damp surfaces as urethane sealants can do. M-Thane™ One-Part is elastomeric and has excellent adhesion to most construction materials. It has a low durometer, which accommodates greater movement in penetration seals than typical urethane sealants.
