Due to the toxicity and environmental protection problems of the curing agent TGIC (triglycidyl isocyanurate) in the polyester powder coating in the synthesis, post-processing and powder coating production and construction, it has been designated as a highly toxic drug in Europe, and its use has been restricted.

The Ministry of Industry and Information Technology of my country also listed TGIC in the list of eliminated products in 2010. This article introduces the synthesis process of TGIC and its impact on the environment and human health. The alternatives are discussed, the current difficulties and future development trends are expounded, and it is considered that it is a trend to gradually replace TGIC and choose HAA system.


The problems existing in the HAA system require continuous efforts from the synthesis of curing agents, the development of new resins, and the optimization of powder formulation processes. It also needs the joint support of aluminum profile spraying manufacturers, building owners, authoritative organizations, and standard-setters.
