Universal moisture-curing adapter foam
Alfa PU-Assembly Foam is a 1K polyurethane foam (moisture-curing) that has excellent acoustic and thermal insulation properties but also avoids the occuring of heat bridges. It bonds very good to concrete, brickwork, metal, plaster, wood and many plastics.
Alfa PU-Assembly Foam is ideal for sealing, filling, insulating of window frames, window sills, wall joints, wall openings/breakthroughs, penetrations, cable bushings at plumbing installations, cavaties, roof constructions, roller shutter boxes, etc.
Thanks to its fine-celled structure, Alfa PU-Assembly Foam is also best suitable for the model-making and mould making as well as for handicraft works.
Fresh foam residues can be removed with Alfa Spray & Gun Cleaner or with Alfa Clewo Wipes Duo+.
