The transparent powder coating produced by our company can be used both indoor and outdoor. Those used indoor are highly protective and mainly used in electroplating, polishing and other work pieces which need special protection. Those used outdoor are divided into two types, pure polyester series and acrylic acid series. The pure polyester series is mainly used as protective bottom layer whereas the acrylic acid series is widely applied in external coating protection of steel rims such as in bicycles, cars and so on for its high transparency and excellent weather resistance.
