LOCTITE® UR 7225 is a brown, solvent-free adhesive, suitable for the manufacture of sandwich elements with porous substrates (e.g. wood,) which contain humidity. The porous substrates can be bonded to one another or to metals, laminated panels, various plastics, and rigid foams made of polystyrene, polyurethane, and more. Moisture-curing, this 1-part adhesive will obtain strength after approximately 50–70 minutes, or more quickly with a heated press – maximum temperature must not exceed 70°C (158°F).
