  • Applications

    N-Octadecyl-1,3,5-triazine-2,4,6-triamine (CAS 21840-04-0) is a triazine-derived amine that functions as a versatile building block and specialty additive; in industry it is used as an intermediate and crosslinking agent for epoxy and polyurethane resins as well as melamine-formaldehyde systems, as a surface-active additive functioning as a surfactant, dispersant, and wetting agent in coatings, inks, and adhesives, as a coupling promoter in polymer composites and coatings to improve substrate adhesion, as a pigment-dispersing additive in paints and inks to stabilize pigment suspensions, and is evaluated as a cosmetic emulsifier/surfactant in personal care formulations, with usage subject to formulation constraints and local regulations.
