one component polyurethane foam sealant, referred to as the polyurethane foaming agent, commonly known as styrofoam, is a product of polyurethane foam aerosol technology and technology are combined. It is a kind of special polyurethane products of polyurethane prepolymer, foaming agent, catalyst and other group packaging are filled in pressure aerosol cans. When the material is ejected from the aerosol tank when the matrix foam polyurethane material can expand quickly and into contact with air or water in the formation of foam. The curing reaction after curing OCF foam with caulking, bonding, sealing, heat insulation, sound absorption and other effects, is a kind of environmental protection and energy saving, convenient use of building materials, applicable to sealing and plugging, Filling the gap, fixed bond, insulation, especially suitable for plastic steel doors and windows, Aluminum Alloy, sealing and plugging waterproof suit doors and windows and the wall.
Products are generally dry time in about 10 minutes (at 20 DEG C environment), dry time with the environmental temperature and humidity varies, in general, the summer dry time of about 4-6 hours, winter around zero to 24 hours or longer to dry. Under normal conditions of use (and in the appearance of a cover case), to estimate the service life of not less than ten years in -10 to 80 DEG C in curing foam had a good elasticity and adhesion. The cured foam with grout, bonding, sealing and other functions. In addition to flame retardant single component polyurethane foam sealant the flame retardant level can be achieved Class B and class C.
Application
Window and door installment:Between the windows and wall sealing, fixed bond.
AD model:Sand table model, making panels repaired.
Insulation:Speech rooms, studios and other decoration to fill the gap, can play a sound silencing effect.
Landscaping: flower arranging, landscaping, light and beautiful.
Daily maintenance: empty, cracks, wall tiles, floor tiles, floor repair.
Waterproof plugging: tap water pipes, sewers and other loopholes in the repair, plugging.
Packaging and transportation: it can easily be a parcel of valuable and fragile goods, saving time and fast, earthquake resistance.
Before the construction, should remove construction surface greasy dirt and dust, and spraying in the construction of small water surface.
Before use, the polyurethane foam can shake for at least 60 seconds, to ensure that the tank material.
If a gun type single component polyurethane foam sealant, use the tank upside down and gun threaded connection, rotate and open the valve, regulating the flow after injection.
If the tube type single component polyurethane foam sealant, plastic test head screwed on the valve threads, the plastic pipe alignment slot, press the nozzle can spray.
Note the travel speed of injection, injection can usually amount to half the volume needed to fill the gap should be filled. The vertical upward filling; such as when the gap, because of the gravity, the uncured foam may fall, suggestions for proper support in just after filling, after curing of the foam and seam wall bonded after the evacuation support.10 minutes, bubble debonding, 60 minutes can be cut. Use a knife to cut the excess portion of the foam, then the surface with cement mortar, coating or silicone coating.
