Advice

  • Unsuitable for applications under water and for filling larger, closed cavities without exposure to atmospheric moisture. Foam does not adhere to materials such as polyethylene, silicone, grease or similar. Cured polyurethane foam is not UV-resistant and must be protected from exposure to UV by being painted over or sealed with sealant (silicone, acrylic, MS polymer). Unsuitable for drinking water wells!
  • Vertical joints and cavities must be filled with foam from the bottom and must not be overfilled. The general application conditions for PU foams apply.
