1,3,5-Triglycidyl Isocyanurate, more commonly known as TGIC, is a chemical compound that plays a significant role across various industrial sectors. With its CAS number 2451-62-9, TGIC is recognized for its efficacy as a crosslinking agent and its utility in enhancing the performance of polymers and coatings. This article provides an in-depth look at TGIC's properties, its extensive applications, and insights into sourcing it from global manufacturers.

Chemically, TGIC is a white crystalline powder with a molecular formula of C12H15N3O6 and a molecular weight of approximately 297.26 g/mol. Its key structural feature is the presence of three glycidyl ether groups attached to an isocyanurate ring. This trifunctional epoxy structure is responsible for its excellent crosslinking capabilities. Typical properties include a high assay (often 99%), a melting point range of 90-125°C, and low volatile content, making it a stable and effective intermediate for demanding applications.

The applications of TGIC are diverse and impactful. It is predominantly used as a curing agent for polyester powder coatings, where it facilitates the formation of a hard, durable, and chemically resistant finish. Beyond coatings, TGIC is indispensable in the manufacturing of laminates, printed circuits, tools, and adhesives, contributing to enhanced strength and thermal stability. It also serves as a cross-linking aid and radiation-assisted cross-linking agent for rubber and plastics, improving their mechanical properties and performance under stress. Its role in electronic printing inks for LCDs and CCDs further highlights its versatility.

For businesses looking to purchase TGIC, understanding the global supply chain is important. Reputable manufacturers, particularly those based in China, offer high-purity TGIC at competitive prices. When seeking to buy this chemical, it is advisable to look for suppliers who can provide consistent quality, reliable delivery, and comprehensive technical support. Engaging with experienced manufacturers ensures that you receive a product that meets your specific application requirements, whether for industrial resins, advanced composites, or specialized electronic components. For those in need of this essential crosslinker, finding a trusted manufacturer is the first step toward optimizing their product formulations.
