Polyurethane(PU) foam sealant is a single component, moisture curing, multi-purposePolyurethaneFoam-filled elastic sealing material. It polyurethane prepolymers, catalyst and gas propellant filling pressure of the iron in aerosol cans, the construction of the glue gun or manually through the auxiliary air nozzle to spray mist to be the construction site colloid, forming short-term complete , foam, adhesive and sealing process. General form of dry time of 10 minutes (at room temperature under 20 ?), total dry time with temperature and humidity vary, in general, all the summer dry for about 4-6 hours, winter is around zero to 24 hours or longer to fully dry. Elastomer with the curing foam adhesive, waterproofing, resistance to thermal expansion and contraction, heat insulation, sound insulation or fire retardant (flame retardant type restrictions) and other excellent properties, are widely used seam side doors and windows, expansion joints and components fill the holes seal. Under normal conditions of use (and its appearance in the case of coverage), to estimate the service life of not less than ten years, at -10 ? ~ 80 ? temperature range of curing foam had a good flexibility and adhesion force.

   Since the turn of the century in the country promote the use of this product has been rapidly expanding its market demand, the current construction market in the country with about 30 million cans in about the improvement of the quality requirements with the construction and energy saving type building promotion of consumption of these products will grow steadily in future.
