Product Description

Product Description

GNS ALL PURPOSE PU FOAM A40 is a one-component, economical type and good performance Polyurethane foam. It is fitted with a plastic adaptor head for use with a foam application gun or a straw. 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 .

Product Feature

1. Good adhesion to a wide variety of surfaces such as UPVC, masonry, brick, block work, glass, steel, aluminum, timber and other substrates (except PP, PE and Teflon);
2. Very good filling capacities;
3. Application temperature is between + 5ºC to +35ºC;
4. Optimal application temperature is between +18ºC to +30ºC;
5. It contains CFC-free propellants which are harmless to the ozone layer

Application Areas

1. Installing, fixing and insulating of door and window frames;
2. Filling and sealing of gaps, joint, openings.
3. Connecting of insulation materials and roof construction;
4. Bonding and mounting;
5. Insulating the electrical outlets and water pipes;
6. Heat preservation, cold and sound insulation;
7. Packaging purpose, wrap the precious & fragile commodity, shake-proof and anti-pressure

Packaging & Shipping

FAQ

Q: If the PU foam shrinks after curing, what effect will it bring?

A: It will damage doors and windows and the performance of PU foam will be reduced.

Q: Why should we choose a PU foam with good elasticity?

A: Because the PU foam with good elasticity will not damage the doors and windows in hot weather, because its structure inside is better.
