Sell Polyester Resin for powder coating

Properties:
It is a carboxyl saturated polyester resin, to be used together with TGIC ( at the rate of *3:7) to produce pure polyester powder coatings, it can giving high gloss, good flow effect, wonderful mechanical properties, pretty decorative effects, excellent yellowing resistance and marked exterior durability.  It also has the functions of salt and alkali resistance, humidity and heat resistance and of acid durability, it can create excellent exterior durability with good flow effect.
