BIWA winter foam B2 gun foam for frost

Description

The BIWA Winter Foam is a 1K polyurethane gun foam that can be processed down to −20 °C. Ordinary building foam no longer cures reliably at these temperatures. The pack contains twelve cans of 750 ml each and thus covers a whole winter season.

Benefits

  • Can be processed down to −20 °C, therefore suitable for building sites even in winter
  • Pack of 12 × 750 ml, designed for longer frost periods
  • Building material class B2 to DIN 4102
  • Low shrinkage, remains dimensionally stable after curing
  • Paintable, connections can be reworked directly

Areas of application

  • Window and door installation at low temperatures
  • Filling joints and cavities on walls, ceilings and floors
  • Thermal and sound insulation as well as sealing indoors and outdoors
  • Winter building sites where standard foam fails

Product details

The foam consists of 1-component polyurethane and is coloured yellow. When cured it withstands −40 °C to +80 °C. Made in Switzerland.

The cans should be brought to temperature and shaken vigorously before use – cold can contents foam less well. Screw upright into the gun and dispense evenly. Remove fresh foam immediately with PU cleaner.
