Dual Valve PU Foam

Selsil Dual Valve PU Foam is polyurethane-based, moisture-cured, one-component filling and insulation material. It has a special valve design that provides many advantages.

Properties

  • One-component
  • Moisture cured
  • Excellent adhesion to most construction materials such as wood, concrete, tile, metal, and aluminum (except polyethylene, silicone, and Teflon)
  • Thermal and acoustic insulation
  • Cuttable and paintable after curing
  • Very good expansion capacity
  • Multi-directional valve- 360° application
  • Higher yield
  • Special valve-new design- suitable pipette for the valve
  • Easy application even in difficult application areas
  • Two functions in one can
  • Does not contain CFC and HCFC gases

Application Area

  • Assembling and sealing of windows and door frames
  • Filling of cavities
  • Sealing of openings in all roof constructions
  • Thermal and acoustic insulation

Limitations

  • Not suitable for PE, PP, PC, PMMA, PTFE, soft plastics, neoprene and bituminous substrates
  • Do not use in applications where continuous water immersion is possible
  • Should not be exposed to UV and be covered paint or plaster

Instructions

The application surface must be solid, clean, dry and free of dust, oil and grease. Surfaces must be moisturized before application of PU foam. The most suitable can temperature for use is between 20–25°C. Shake the tube vigorously about 30 times before use. Foam extrusion can be controlled by varying pressure on the adaptor. For best output, position the valve downward. The valve works 360°.

Cleaning

Fresh foam can be cleaned with Foam Cleaner before curing. Cured foam can only be removed mechanically with knife or spatula.
