Technical Specifications

Industrial Applications

This versatile silane is extensively used as a coupling agent and surface modifier in the coatings and sealants industry. It significantly improves the mechanical and chemical properties of composite materials by optimizing the interface between organic resins and inorganic fillers. In the production of silane-terminated polymers, such as MS polymers and silicon-based modified polyurethane polymers, it acts as a crucial resin modifier. Furthermore, it serves as an effective crosslinker and tackifier for room temperature vulcanizing (RTV) silicones, enhancing the adhesion between rubber compounds and various substrates. Manufacturers seeking equivalents to major brands find this product to be a reliable drop-in replacement for high-performance formulations.
