Cas no 666829-33-0 (BIS(3-TRIETHOXYSILYLPROPYL)POLYETHYLENE OXIDE (25-30 EO))

BIS(3-TRIETHOXYSILYLPROPYL)POLYETHYLENE OXIDE (25-30 EO) is a silane-terminated polyethylene oxide derivative, featuring a hybrid organic-inorganic structure. The triethoxysilyl groups enable covalent bonding to inorganic substrates, while the polyethylene oxide (PEO) chain (25-30 EO units) provides hydrophilicity, flexibility, and compatibility with polar matrices. This bifunctional compound is particularly useful in surface modification, adhesives, and coatings, where it enhances wetting, adhesion, and dispersion properties. Its hydrolyzable ethoxy groups facilitate crosslinking with silanol-containing surfaces, improving durability and chemical resistance. The PEO segment also contributes to reduced interfacial tension and improved biocompatibility, making it suitable for specialized applications in biomedical and composite materials.
