Epoxy Resin & Polyester Hybrid Powder Coating
Epoxy resin and polyester hybrid powder coating is made from raw material of epoxy resin and polyester resin. It inherits advantages of both materials that make the film coating with optimal ornamental, mechanical features and better erosion resistance. It is applicable to various coating of indoor metalwork.
Product series
We offer standard type and cryogenic curing powder coating products. It can produce the product of high gloss (above 80 percent), half gloss (50-80 percent), sub-gloss (20-50 percent), and the matt. The gloss can also be adjusted according to the client's instruction.
