5. UV-Curing Ink and Coating Additive Manufacturing

Industry formulators utilize this chlorinated triazine as a minor additive to enhance crosslinking speed and film hardness in UV-cured inks and wood coatings. The highly reactive chloro positions facilitate rapid curing under ultraviolet irradiation, supporting rapid throughput in high-end printing and finishing lines. The addition ratio is fine-tuned to the resin type and end-use gloss or abrasion resistance requirements, ensuring minimal impact on color and transparency while optimizing cure profile.

Industry compliance standards
