  • Applications

    Dihexadecylamine (CAS 16724-63-3) is primarily used as a long-chain surfactant and as a precursor for quaternary ammonium salts, enabling the production of cationic surfactants for surface treatment, coatings, and polymer formulations. It serves as an intermediate in the synthesis of long-chain surfactants and polymer additives to improve dispersion, compatibility, and adhesion. It can act as a phase-transfer catalyst or emulsifier in certain chemical processes. It is also used as a component in corrosion-inhibition formulations for metal surfaces and as an adhesion promoter or coupling agent in coatings, inks, and adhesive systems. Depending on formulation and local regulations, its use is handled under applicable regulatory and formulation limits.
