Triglycidal Isocyanurate (TGIC)

Triglycidyl Isocyanurate TGIC
Triglycidyl Isocyanurate TGIC

The TGIC is a kind of heterocyclic epoxy compound, is also named Triglycidyl Isocyanurate. It has very good heat resistance, weathering resistance, adhesion and excellent high temperature performance. It is mainly used for containing carboxyl polyester, carboxyl acrylic resin powder coating of the curing agent. The TGIC is always used as curing agent. High purity of TGIC can be used in the manufacture of electrical insulating laminated board, adhesive, plastic stabilizer, etc. (TGIC) is added to powders as a cross-linking agent to enhance durability and finish.

It is known to increase the sensitivity of the skin and respiratory tract, is toxic by ingestion and inhalation and may cause serious eye damage. Triglycidal Isocyanurate (TGIC) is an odorless white powder or granules. It is insoluble in water and has the potential to be explosive.Triglycidal Isocyanurate is widely used as a cross-linking agent or curing agent in powder coating industry, It is used also in the printed circuit board industry, electrical insulation and as a stabilizer in plastic industry.

Hardener for polyester based outdoor durable powder coating.
