GNS Tianjin factory spray insulation polyurethane foam waterproof expanding PU foam for construction
GNS Tianjin factory spray insulation polyurethane foam waterproof expanding PU foam for construction is a one-component, ready to use multi-purpose Polyurethane Foam. It is fitted with a plastic adapter head for use with a foam application gun or plastic applicator. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation.
PRODUCT FEATURES
