2K PU foam means double the power and double the speed. The OTTOPUR OP 920 is a two-component polyurethane adapter foam that impresses with its very fast curing time – ideal for job sites where speed matters. This 2K PU foam also delivers excellent thermal insulation and very good sound insulation, and it's suitable for both indoor and outdoor use.
This 2K PU foam shows its strength wherever installation and insulation need to go hand in hand: installing and insulating door frames and window frames made of wood, steel or PVC set into masonry, installing wooden stair treads, and fitting acrylic or steel bathtubs and shower trays.
This 2K PU foam impresses with its speed: the OTTOPUR OP 920 is cuttable after just 9 minutes, de-wedgeable after 30 minutes, and fully load-bearing after only 3 hours. Yield is up to 12 litres per 400 ml can.
This 2K PU foam holds a general building authority test certificate as a normally flammable material (B2 per DIN 4102-1) and is rated EMICODE® EC1 PLUS for very low emissions. It also meets French VOC emission class A+.
This 2K PU foam applies easily without a special dispensing gun, making the OTTOPUR OP 920 especially flexible, including for spontaneous repairs.
