Polyurethane Foam Sealant

Polyurethane foam caulk is a one-component, moisture-curing, multi-purpose polyurethane foam filler and sealant. Its cured foam elastomer has excellent properties such as bonding, waterproofing, resistance to thermal expansion and contraction, heat insulation, sound insulation and even flame retardant (flame retardant only). It is suitable for gap filling, crack and fracture sealing
