Single-component high-quality PU-foam with very low expansion for filling pressure-sensitive joints. Pressure on joint sides two times lower than the regular PU-foam. Very homogeneous dense structure and minimum post expansion. Good resistance to moisture and mould. Fast curing. Great results at low temperatures. Packed in an aerosol can, can be used with a foam gun, moisture curing. Cured foam is a good temperature and sound insulator. The foam has very good adhesion properties. Adheres well to most construction materials, except Teflon, polyethylene and silicone surfaces. After curing does not resist UVradiation and needs to be covered.
