Silicon modified polyester (SMP) color coated steel sheet

Because polyester contains active OH/-COOH, in order to improve the sunshine resistance and powdery property of ordinary polyester, using silicone resin with excellent color retention and heat resistance as denatured reaction, silicone modified polyester coating can provide steel plate with better film hardness, heat resistance, wear resistance and durability, and its anti-corrosion ability can be up to 10-15 years，and has good external durability and powder resistance, but luster retention and flexibility are moderate, medium cost.
