Description

Silane, Trimethoxy3-(Oxiranylmethoxy)Propyl-, Hydrolysis Products With Silica is a specialized organosilane-silica hybrid material, formed from the hydrolysis and condensation of an epoxy-functional silane with silica. This product is engineered to provide superior surface modification and coupling properties, enhancing the adhesion and compatibility between organic polymers and inorganic substrates. It is a critical component for formulators and manufacturers in the composites, coatings, and adhesives industries seeking to improve mechanical performance and durability.

Application

• Composite Materials: Acts as a coupling agent and surface modifier in fiberglass, mineral-filled, and silica-reinforced polymer composites to improve interfacial bonding and mechanical strength.
• Adhesives & Sealants: Enhances the adhesion of epoxy, polyurethane, and silicone-based formulations to glass, metals, and ceramics, providing improved moisture resistance and durability.
• Coatings & Paints: Used as an additive in protective and decorative coatings to promote substrate wetting, increase corrosion resistance, and improve scratch and chemical resistance.
• Rubber & Elastomers: Serves as a reinforcing agent in silica-filled rubber compounds (e.g., tires, industrial belts) to enhance dispersion, reduce viscosity, and improve tensile and tear properties.
• Electronics Encapsulation: Improves the adhesion and stress relief of epoxy molding compounds and potting materials used to protect sensitive electronic components.
• Surface Treatment: Applied as a primer or treatment for glass, metals, and minerals to create a reactive, organofunctional surface for subsequent bonding or coating processes.
