Description
DEMSUN P55 is a single-component polyurethane foam that expands and cures through moisture exposure, delivering reliable sealing and insulation in one application. The included straw adapter ensures precise dispensing, while the ozone-safe formulation meets modern environmental standards. Once cured, the rigid foam resists mold and water, bonds securely to most building substrates, and accepts trimming, shaping, and paint finishes. Ideal for securing door and window frames, sealing gaps and joints, filling wall penetrations, and insulating pipes and electrical outlets. Avoid application on polyethylene, Teflon, silicone, or oil-contaminated surfaces for optimal adhesion.
