What is Triglycidyl isocyanurate?
Triglycidyl isocyanurate (CAS 2451-62-9), commercially known as TGIC, is a trifunctional epoxy compound used as a crosslinker and curing agent in thermosetting polymer systems.
Where is Triglycidyl isocyanurate used?
- Coatings: reacts with carboxyl-functional resins to build durable, chemically resistant networks in high-performance industrial formulations
- Powder coatings: primary crosslinker in polyester-based systems for outdoor durability, UV resistance and mechanical strength in architectural finishing
- Electronics: epoxy encapsulants and printed circuit board laminates requiring dimensional stability under thermal cycling
- Aerospace and defense: structural adhesives and composite matrices resistant to elevated temperatures and aggressive environments
- Flexible packaging inks and coatings demand strong substrate adhesion and chemical resistance.
Commercial specifications
- Purity: 98% and above in standard commercial grades
- Packaging: kilogram-scale bags to bulk quantities
