High Expansion Polyurethane Foam Adhesive For Filling / Sealing Cas 51852 81 4
Multipurpose large expansion PU foam sealant is an one-component, self-expanding,multipurpose polyurethane foam. This 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. Higher expansion rate than normal Pu foam.
