This specialty silane coupling agent, featuring a hydrophilic triethyleneoxy chain, is used as a surface modifier in coatings, adhesives, and sealants to enhance adhesion on polar and inorganic substrates like glass and metals. It improves wettability and compatibility between organic polymers and inorganic fillers, particularly in water-based or aqueous systems, making it ideal for hybrid materials and biomedical applications. Commonly incorporated into silicone-based formulations to impart flexibility, durability, and hydrophilic properties. Also employed in the production of stable emulsions, dispersions, and anti-fog coatings where performance in humid environments is essential.
