Octadecyltrimethoxysilane ODTMS 3069-42-9

It is an efficient organic silane coupling agent with the molecular formula C ₂₁ H ₄₆ O ∝ Si. It appears as a colorless to pale yellow transparent liquid. Its molecule contains long-chain hydrophobic octadecyl and three hydrolyzable methoxy groups. After hydrolysis, it can form strong Si-O covalent bonds with inorganic substrates such as glass, ceramics, and metals, significantly improving waterproof, anti fouling, and compatibility with organic compounds
