  • Applications

    Ethylphenyldichlorosilane, CAS 1125-27-5, is primarily used as an organosilicon intermediate to synthesize aryl-alkyl silanes and to prepare silicone polymers and resins; it also serves as a silylation reagent and a precursor for silane coupling agents that improve adhesion between organic polymers and inorganic surfaces. In practice, applications include coatings and inks based on silicone resins, adhesives and sealants, and surface modification in electronics, such as silanizing glass and semiconductor surfaces to enhance bonding and thermal stability; the phenyl substituent helps provide higher thermal resistance and refractive index in resulting materials.
