  • Applications

    Cyclohexenyltrichlorosilane (CAS 10137-69-6) is used as a vinyl silane coupling agent and reactive monomer in coatings, adhesives, and composite formulations. It enables bonding to inorganic substrates such as glass, silica, and metal oxides, while the cyclohexenyl vinyl group can participate in polymerization or crosslinking to improve adhesion and durability; it also serves as an intermediate for synthesizing functional silane coupling agents and surface modifiers to tailor the compatibility between organic polymers and inorganic fillers.
