Waterproof polyurathane expanding spray pu foam sealant specially used for holes filling in construction installation, with properties of adhesion, fixing, thermal and acoustical insulation, sealing, waterproof, damp proof, gas isolation, shock proof, insulation and so on. Widely used in fixing and bonding of windows, wood doors, wood strips, skirting board, wood floor, insulation board, air conditioner, switch, socket and filling of contraction joint of wall and all types of holes on pipes.
1. Fast filling
One component foaming fill, convenience, easiness, efficiency, and reduced labor are promised in application.
2. High filling degree
fter polyurethane prepolymer is ejected, its volume increases rapidly, filling the hole to its extreme depth and ensuring high filling degree.
3. Good cohesive force
Thanks to multiple carbamate radicals contained, polyurethane foam can tightly adhere to cement mortar and PVC plate, ensuring that the wind pressure to the window frame is evenly distributed among the four walls of the opening, instead of being withstood exclusively by spanker bolts on several fixed plates.
4. No side-effcet
When filling and foaming, excessive foam will flow out, without causing deformation of the window frame.
5. High sealing performance
Ultimately, polyurethane foam will constitute a half rigid closed cell material that blocks air flow, insulates sound waves, and resists shock.
6. Easiness in finishing
As the foam cures, the protruding part can be cut and trimmed by a cutter easily.
7. Surface painting
As the foam cures, brushing the surface with coatings and emulsion paints can prevent aging due to exposure to ultraviolet.
8. Long service life
Properly painted open-air PU foam will not be prone to aging, giving a service life up to 50 years.
9. Self-extinguishing performance
Flames on PU Foam will be automatically extinguished, showing compliance with the DIN 4102-B2 requirements.
10. Wide applicability
Curde foam can put up with temperature -30°C—— 100°C,with resistance against solvent, acid, and alkali.
11. Environment-friendliness & energy conservation
CFC free foam does not harm the atmospheric ozone layer. Besides, the cured foam causes no hazards to human and the high sealing performance ensures reduced loss of energy.
12. No corrosion
The foam has no corrosive effect on the window frame material.
