Improvement Weatherability of Powder Coating Based on Polyester Resin

Powder coating received much attention due to its energy saving and environmental protection in the past decade.In this paper,the mechanism of ageing degradation and the affected factors on weather resistance of powder coating based on polyester resin were introduced briefly.The new development of improving powder coating based on polyester resin weather resistance was reviewed especially.In the end,it prospected the implement of super durable polyester powder coatings.
