SPU Sealant

 SPU Sealant refers to silanized polyurethane,  SPU Sealant is a polyurethane-based chain modified by silane sealing material, this type of sealant in addition to retaining the advantages of the original PU sealant, in terms of heat resistance, aging resistance, weather resistance have been greatly improved, the metal, glass, PVC and other commonly used substrates have a good adhesive effect. "Silicone" polyurethane, one-component moisture-curing polyurethane (PU) sealant is widely used in civil engineering and construction, transportation and other fields, with high strength, good elasticity, tear resistance, abrasion resistance, resistance to puncture, non-polluting to the substrate, acid and alkali resistance and organic solvents, can be coated with paint, etc., and it does not contain free isocyanate. No polluting curing exudate escapes, will not contaminate the surface and periphery of the adhered substrate, more in line with the requirements of environmental protection.
