1,3,5-triglycidyl isocyanurate (TGIC) is a white powder or granular solid and is normally sold under the trade name ARALDITE PT810R or TEPIC G R. As a tri-functional epoxy monomer, TGIC is used in large scale as curing agent for powder coatings or for cross-linking elastomers. Rosin acids of natural origin may also be cured with TGIC for versatile applications. TGIC has also been used for pharmaceutical purposes, in membranes, for curing intelligent gels or liquid crystal elastomers. Especially, this curing agent has been widely used in dry powder coating for over 40 years.
It has been known that TGIC is toxic by inhalation and if swallowed. It is a severe eye irritant, and a mild skin and nasal irritant, although it has the potential to cause skin sensitisation in people which can lead to severe skin rashes. Exposure to TGIC in powder paints may cause not only contact dermatitis, but also occupational asthma. Kidney damage has also been observed in rats repeatedly exposed to TGIC by oral dosing, and damage to the developing sperm cells has been observed in mice repeatedly exposed to TGIC orally and by inhalation. There is an evidence that exposure of males to TGIC produces genetic changes in the sperm which may lead to heritable effects in the offspring. There is cause for concern that these effects could occur in humans, so that TGIC has been classified in the EU as a Category 2 mutagen. Exposures to TGIC during manufacturing procedures have been identified as hazardous to workers.
Occupational contact dermatitis can occur
in people producing this chemical, in those producing
the powder coat paint and in sprayers.
Triglycidyl isocyanurate is used as cross-linker in heat-cured polyester paints, such as laminated sheetings, printed circuits, tools, inks, adhesives, lining materials etc.
TGIC 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.
Typical applications of polyester TGIC powder coatings are where sharp edges and corners exist such as on automotive wheels, air conditioners, lawn furniture, and air conditioner cabinets.
1,3,5-triglycidyl isocyanurate be used for curing agent of polyester and acrylic resin carboxyl-containing powder coating, manufacturing an electrical insulating laminates, adhesives, plastics stabilizers.
Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Flash point data for 1,3,5-Triglycidyl isocyanurate are not available; however, 1,3,5-Triglycidyl isocyanurate is probably combustible.
Flammability and Explosibility
Non flammable
Triglycidyl isocyanurate is a triazine epoxy compound
used as a resin hardener in polyester powder paints, in
the plastics industry, resin molding systems, inks, and
adhesives. Occupational contact dermatitis can occur in people producing this chemical, in those producing
the powder coat paint, and in sprayers. Respiratory
symptoms have been observed.
