Product Introduction
KH-501 Silane Coupling Agent – High Purity Functional Silane Manufacturer Supply
1. Product Introduction
KH-501 Silane Coupling Agent is a high-efficiency, versatile functional organosilane modifier with excellent hydrolysis and crosslinking properties. It is a colorless to pale yellow low-viscosity transparent liquid at room temperature, featuring dual reactive functional groups in its molecular structure. The hydrolyzable groups can react with hydroxyl groups on the surface of glass, minerals, metal oxides, and other inorganic substrates, while the organic functional groups form stable bonding with polymer materials.
This silane coupling agent effectively bridges inorganic fillers and organic resins, significantly improving interfacial adhesion, dispersion, and compatibility between heterogeneous materials. It solves common industrial problems such as poor bonding, easy delamination, and uneven filler dispersion in composite materials. With stable chemical properties, low volatility, and excellent weather resistance, KH-501 has become a mainstream additive widely used in adhesives, coatings, rubber and plastic composites, and electronic insulation materials, providing long-term and stable modification effects for industrial products.
