Description

(n-Cyclohexylaminomethyl)Methyldiethoxysilane is a specialized organosilicon coupling agent featuring both an alkoxysilyl group and a secondary amine functional group. This dual functionality makes it a highly effective adhesion promoter and surface modifier, bridging organic polymers and inorganic substrates. It is primarily used by formulators in the adhesives, sealants, coatings, and composite materials industries to enhance mechanical properties and long-term durability.

Application

• Adhesion Promoter: Enhances the bond strength between organic polymers (e.g., epoxies, polyurethanes) and inorganic surfaces like glass, metals, and minerals.
• Filler Treatment: Used to modify the surface of silica, clay, and other mineral fillers to improve dispersion and compatibility within polymer matrices.
• Fiberglass Sizing: A key component in sizing formulations for glass fibers, improving the fiber-resin interfacial adhesion in reinforced plastics and composites.
• Water-based Coating Additive: Acts as a crosslinking agent and stabilizer to improve the water resistance and adhesion of acrylic and other aqueous coating systems.
• Rubber Compounding: Improves the reinforcement of silica-filled rubber compounds, leading to better abrasion resistance and lower rolling resistance in tire applications.
• Mineral and Stone Protection: Serves as a precursor in formulations for hydrophobic surface treatments and consolidants for construction materials.
