Product Description

Single-component waterproof polyurethane expanding spray PU foam sealant adhesive

Single-component waterproof polyurethane expanding spray PU foam sealant adhesive is a one-component, ready to use multi-purpose Polyurethane Foam. It is fitted with a plastic adapter head for use with a foam application gun or plastic applicator. 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 FEATURES

• 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);
• Very good filling capacities;
• Application temperature is between + 5ºC to +35ºC;
• Optimal application temperature is between +18ºC to +30ºC;
• It contains CFC-free propellants which are harmless to the ozone layer.
