[Description]

Triethoxyoctylsilane 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.
