1. It can be applied to damp surfaces.


2. OCF is moisture curing.The more moisture, the quicker the cure.


3. It must be protected from Uvin External application to prevent

    discoloration and deterioration of the foam.


4. Conventional paints can be applied to the foam.


5. In can be used in temperature range of 5-40°C,if in low temperature condition,

    we suggest that it should be placed in 25-30°C circumstance for 30 minutes to

    ensure the better performance.


6. Uncured foam can be removed with solvent. But after cure,

    foam can only be removed mechanically.

    Uncured foam sticks to hands and clothing.

Product Features:                                                                                      


One component foaming fill, convenience, easiness, efficiency, and reduced labor are promised in application.

High filling degree


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.


When filling and foaming, excessive foam will flow out, without causing deformation of the window frame.


Ultimately, polyurethane foam will constitute a half rigid closed cell material that blocks air flow, insulates sound waves, and resists shock.


As the foam cures, the protruding part can be cut and trimmed by a cutter easily.


As the foam cures, brushing the surface with coatings and emulsion paints can prevent aging due to exposure to ultraviolet.


Properly painted open-air PU foam will not be prone to aging, giving a service life up to 50 years.


Curde foam can put up with temperature -30°C—— 100°C,with resistance against solvent, acid, and alkali.



The foam has no corrosive effect on the window frame material.
