PS500 Series Spray Polyurea
PS500 Spray polyurea series is a 100% solids, two-component, fast-, high-performance on-site spray molding materials. The A compone curing nt of the product is an isocyanate prepolymer, the B component is an amino terminated polyether, a polyether polyol, a chain extender and a pigment, which has the advantages of high strength, good performance and quick construct PS500 series of products for high elasticity coating, with high elongation at break, generally used for non-metallic substrate, such as: waterproof concrete, foam substrate protection. Among them, PS500A as the basic type, product performance in line with GB / T23446-2009, used for waterproofing concrete substrates; PS500b is on the PS500A basis of ethylene modification, the coating has a certain degree of density and uniformity, antioxidant capacity Stronger, can be long-term use at a temperature of 120 ℃, is an upgraded version of the PS500a; PS500c in PS500b based on fluorine-silicon modified, its corrosion resistance and high temperature resistance has been greatly improved, with excellent acid Alkaline performance, long-term use at 150 ℃ temperature, suitable for power plant desulfurization flue corrosion. PS500d production using a special polyether and chain extender and other new materials, with high resilience and fatigue resistance, more for the ship fenders, floating ball and other offshore facilities.
Roof protection, sewage treatment pond, parking lot, workshop floor, sports stand, sports field, tunnel, culvert, grain warehouse and other concrete substrate protection occasions.
The basic type of PS500 series conforms to the standard GB/T234465-2009 and is used for waterproof protection of concrete, wood and foam base materials.
Chemical plant sewage treatment pool, accident pool, urban sewage treatment pond, metal roof, planting roof, chemical workshop floor and other heavy duty anti-corrosion occasions, as well as all applications of SPE-120a.
Ethylene modification is carried out on the basis of PS500a. It is upgraded version of PS500, and its properties have been improved. Its oxidation resistance and aging resistance have been greatly improved.
Special occasions such as desulphurization flue of power plant, sewage treatment pool of chemical plant, accident pool and other special occasions
On the basis of PS500b, fluorosilicone modification is an upgraded version of PS500b. Its corrosion resistance and high temperature resistance have been greatly improved, and it has excellent acid and alkali resistance.
The skin of the fender, the duckweed, the floating cushion, the lifeboat, and other marine facilities
PS500d has used new materials such as special polyether and chain extender in production, which has high resilience and fatigue resistance.
The protection of the foam on the European component, the film and television props, the landscape sculpture and so on
Its hardness and performance are specially designed for the use of foam
