TGIC

TGIC, or triglycidyl isocyanurate, is a chemical compound with the formula C6H9N3O3. It is a white crystalline solid at room temperature. TGIC is primarily used as a crosslinking agent in powder coatings, particularly those based on polyester resins. This crosslinking process improves the durability, adhesion, and chemical resistance of the coating. It is also used in other applications such as adhesives and electrical insulation.

The synthesis of TGIC typically involves the reaction of cyanuric acid with epichlorohydrin in the presence of a catalyst. It is important to handle TGIC with care as it can be irritating to the skin and eyes, and appropriate personal protective equipment should be used. Environmental and health regulations govern its production and use. TGIC is known for its ability to cure at relatively low temperatures, making it suitable for heat-sensitive substrates. Its widespread use in the coatings industry is due to the desirable properties it imparts to finished products, contributing to their longevity and performance.
