Matt Hardener As Light Yellow Powder Used For TGIC Powder Coatings System
Introductions
TGIC ( Triglycidyl Isocyanurte ) is an isocyanuate based crystalline polyepoxide compound. Its molecular weight is 297(CAS No.2451-62-9). It has good heat resistance, weather resistance, adhesion and high temperature stability.
Feature
1, Used as cross-linked hardener for pure polyester powder coatings. The usage is about 7-9% of the polyester weight (depending on acid value);
2, Used as cross-linked hardener for carboxyl-contained acrylic resins. The usage is about 7% of resin weight (depending on acid value);
3, Used to produce high performance electrical insulating materials, self-extinguishing polymer materials (as stabilizer of fire-retardant), modified epoxy resins, high effect adhesives, stabilizer for plastic materials, etc.
