  • Applications

    Siloxanes and Silicones, di-Me, 3-aminopropyl group-terminated (CAS 106214-84-0) is an amino-functional siloxane used as a reactive intermediate and functional additive in silicone-based formulations. In practice, it serves as a coupling agent and adhesion promoter for coatings, inks, and adhesives; as a crosslinking or chain-terminating agent in silicone elastomer and resin systems; as a surface modifier and filler compatibilizer in polymers and inorganic fillers; and as a starting material for polyurethane or epoxy resin formulations via its amine groups to enhance bonding to substrates or to participate in curing. It can also be employed as a functional additive in electronic or specialty coatings where improved adhesion to glass, metal, or other substrates is beneficial, subject to formulation constraints and regulations.
