Used as a surface modifier and coupling agent in silicone-based formulations to improve adhesion between organic and inorganic materials. Enhances the stability and compatibility of coatings, sealants, and composites, particularly in moisture-curable systems. Commonly applied in adhesives and electronic encapsulants where low ionic content and high purity are critical. Also serves as a hydrophilic spacer in specialty surfactants and functional fluids, providing flexibility and water dispersibility in industrial and pharmaceutical applications.
