Expanding PU Foam
Polyurethane Foam, expand foam
KNG Expanding PU Foam is a one component isolation and construction foam developed to make a seal between construction parts. The foam cures in response to humidity from air and from building materials. This versatile single component adaptor foam in aerosol cans is a practical solution for craftsmen who prefer to work without a PU Foam gun. Like all types of KNG foam the product combines excellent insulation characteristics with perfect adhesion on a wide range of substrates such as timber, brick, natural stone, concrete, plaster, metals and most plastics.
Joints between separation walls, ceiling and floors. Joints around transits of wires and piping through walls and floors. Perimeter joints around window and doorframes.
In general the foam has an excellent adhesion on concrete, brick, stone, plaster, wood, metal and many plastics like polystyrene foam, rigid PU foam and uPVC.
