Application
Mainly used as curing Agent for polyester powder coating. It imparts good weather stability due to its very stable chemical nature. It provides good reactivity through its free functional hydroxyl groups when it is combined with resins containing carboxyl groups as saturated polyesters. The powder will cure with no emit of VOC.
