Advanced Polymer · AP-Silane

AP-Silane 32 is a multifunctional amino-functional coupling agent composed of N-β(aminoethyl)-γ-aminopropyltrimethoxysilane. With both organic and inorganic reactivity, it enhances adhesion and mechanical performance in composite systems. It is especially effective in epoxy, urethane, phenolic, and melamine resins, significantly improving wet and dry tensile, compressive, flexural, and modulus properties. AP-Silane 32 is an ideal additive for paints, coatings, and composite applications requiring superior adhesion and durability.
