On May 19, 2026, the safe use of epoxy resin curing agents, key industrial raw materials, has attracted wide attention in the industry. The higher the chemical activity of curing agents, the greater the toxicity risk. They mainly pose four hazards: acute toxicity, skin and mucous membrane irritation, allergic reactions and chronic poisoning, with significant risk differences among different types. Amine curing agents have the strongest toxicity and are potent skin sensitizers, easily causing acute poisoning and corrosion. Acid anhydride ones mainly harm the respiratory tract with strong dust irritation. Imidazole ones are corrosive; 2-methylimidazole is listed as a Group 2B carcinogen, and its powder also has explosion risks. The industry reminds that proper protection is required during operation: wear suitable gloves, goggles, respiratory protection and chemical protective clothing. Rinse immediately upon contact; seek medical help promptly for inhalation or ingestion. Enterprises should improve safety regulations, strengthen training and physical examinations to build a solid line of defense for occupational health, ensuring production while protecting practitioners.
