Product Description

Product Description

GNS All Season PU Foam

GNS ALL SEASONS PU FOAM W33 is a one-component, self-expanding, ready-to-use, Multi-purpose Polyurethane Foam. The foam will expand and cure by moisture in the air. It is used for a wide range of building applications. It is very good for filling and sealing with excellent mounting capacities, high thermal and acoustical insulation. It is special designed for applications at temperature as low as -18ºC.
 

1. Does Not slump at low temperature;
2. Application temperature between -18ºC to +35ºC;
3. Optimal application temperature between +18ºC to +30ºC;
4. It contains CFC-free propellants which are harmless to the ozone layer.
