Key Facts
TGIC (1,3,5-triglycidyl isocyanurate, CAS 2451-62-9) is a crystalline polyepoxy curing agent for polyester powder coatings, manufactured by Huangshan Deping Chemical Co., Ltd. Its EINECS number is 219-514-3, its molecular formula is C12H15N3O6, and its molecular weight is 297.26 g/mol. TGIC offers excellent heat resistance, weatherability, adhesion and high-temperature stability, and is a preferred curing agent for outdoor durable polyester powder coatings.
Huangshan Deping Chemical supplies four TGIC grades: TGIC, TGIC-08, TGIC-801 and TGIC-802, with epoxy equivalents of at most 110 g/eq for the standard grade and progressively lower chlorine and epichlorohydrin contents in the higher grades (TGIC-802: chlorine below 650 ppm, epichlorohydrin at most 20 ppm). Melting ranges are 85-125 °C depending on grade. TGIC is also used in electrical insulation materials, laminates, printed circuits and adhesives. It is packed in PE-lined bags of 20 kg or 25 kg and can be stored for at least 1 year at 0-40 °C in sealed bags.
Frequently Asked Questions
What is TGIC used for?
TGIC is mainly used as a curing agent for polyester powder coatings, especially outdoor high-weatherability systems. It is also used in electrical insulation materials, laminates, printed circuits, adhesives and as a stabilizer for plastics.
What TGIC grades does Deping Chemical offer?
Four grades are offered: TGIC, TGIC-08, TGIC-801 and TGIC-802. They differ mainly in chlorine content and epichlorohydrin content, which decrease from the standard grade to TGIC-802 (chlorine below 650 ppm, epichlorohydrin at most 20 ppm).
Is TGIC suitable for outdoor applications?
Yes. TGIC-cured polyester powder coatings offer excellent weatherability, heat resistance and adhesion, making TGIC one of the preferred curing agents for outdoor durable powder coatings.
How should TGIC be stored, and what is its shelf life?
TGIC is packed in flat PE-lined bags of 20 kg or 25 kg net weight. Under cool (0-40 °C) and dry conditions in sealed bags, it can be stored for at least 1 year. Opened bags should be resealed immediately after use.
