- Product Application
- The curing mechanism of polyester / TGIC powder coating is that polyester resin containing carboxyl groups carring out the ring-open addition reaction with TGIC's glycidyl groups to achieve crosslinking and film curing. Because of no volatile generation during the film curing reaction, the polyester/TGIC powder coating can be made non-porous thick film.
- TGIC is a cyclic multi-oxygen compound; its stable epoxy structural determines that film curing polyester has excellent weather resistance. Inexpensive and excellent weather resistance of the polyester/TGIC powder coatings render its characteristics of outdoor widely used.
- TGIC has good compatibility with the carboxyl polyesters which belong to terephthalic acid-neopentyl glycol-trimellitic anhydride polymers. The acid range of carboxyl polyesters is 30-70, softening point is 70-110℃ and hydroxyl groups.
- The Recommended Dosage
The use level is 7~8% by weight of polyester resin,Please according to the test to determine the specific amount.
