Applications

Silane OSi HIOSil OCTEO is an essential alkyl silane in the following industries:

■ It Can be used in the formulation of water-repellent products. Triethoxyoctylsilane is used as a building waterproofing agent and protective agent to form a hydrophobic layer on the surface of the substrate, effectively preventing water seepage, sun exposure, acid, and alkali corrosion, and prolonging the service life of the building.

■ Surface modification can improve compatibility with nonpolar substrates. Triethoxyoctylsilane is used as a surface agent for inorganic fillers to improve the dispersibility and compatibility of fillers in plastics, rubbers, and resins.

■ It is used as a dispersant for pigments to provide better dispersibility of the treated pigments.
