Description
There are 2 types of polyester powder coatings, which are TGIC and TGIC-free. Pure polyester powder coating offers good UV resistance and weatherability. It also provides excellent flexibility and mechanical properties. Polyester powder coating can be applied on substrates requiring outdoor durability.
Features
