  • Applications

    1,3,5-Triethylhexahydro-1,3,5-triazine (CAS 7779-27-3) is used primarily as an intermediate and processing additive in plastics, coatings, and adhesives. In epoxy resin systems and other thermosetting polymers, it often acts as a curing agent or crosslinking partner, improving film hardness and thermal performance of the coatings. It is also employed as a precursor for specialty chemicals and can participate as a processing aid to modulate rheology and compatibility in polymer formulations, paints, and adhesives.
