Polyurethane expanding foam

Polyurethane expanding foam is a expanding foam, expanding frequently used for insulating gaps, sealing around newly-installed windows, sealing cracks or gaps in old roof structures, and prevent energy loss.

This foam glue spray is dispensed through a contractor grade gun for control and ease of use.  The gluing polyurethane foam gun can be metered down which allows precise control of the flow output. And after you squirt it out, it usually looks like a thick, solid yellowish foam that expands over time as it dries and hardens.

Characteristics and advantages:

+ Low foaming, high strength, polyurethane fixing foam adhesive
+ Easy to install
+ High strength interior and exterior panel adhesive suitable for use on new construction items
+ Very strong and fast grab, no need for mechanical fastenings
+ Suitable for bonding substrates with extremely irregular surfaces
+ Useable for indoor and outdoor applications
+ Suitable for vertical and horizontal applications
+ HFC-free, safe for your health and eco-friendly environment

Appliacation:

- Sealing cracks or gaps on the walls or doors
- Installing panel in cold storages.
- Sealing and combining cracks between wall and the pipes through the wall.
- Mainly used in sound insulation, thermal insulation, waterproofing, in civil and industrial construction, cold storage, industrial electricity, Automotive , etc.
