Triethoxyoctylsilane Usage And Synthesis
DescriptionTriethoxyoctylsilane is a monomeric medium-chain alkylfunctional silane. It is a clear colourless liquid and soluble in common non-polar organic solvent.
Triethoxyoctylsilane can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigments, or mineral fillers).
When diluted with an appropriate solvent, it can be used in the formulation of water repellent products. Upon proper application, the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate. Treated substrates are hydrophobic and retain their original appearance.
Chemical PropertiesColorless transparent liquid
UsesTriethoxy(octyl)silane is a hydrophobization agent used to limit coalescence in solid-stabilized emulsions.
General DescriptionTriethoxy(octyl)silane (TEOS) is an alkoxide organosilane with four ethyl ester sidechains. It is used as a self-assembled monolayer and provides a hydrophobic coating with low surface energy. The water contact angle is in the range of 150-170°.
