n-Octyltriethoxysilane Description

n-Octyltriethoxysilane(CAS 2943-75-1) also known as Triethoxyoctylsilane. It is a transparent colorless oily solution, mainly used for defoaming of coatings.

Triethoxyoctylsilane is a kind of monofunctional silane, which can modify the surface of glass, quartz sand, metal, powder filler, etc., thus obtain good hydrophobic properties and improve the compatibility of filler with resin; Meanwhile, CAS 2943-75-1 Silane can be used in tires Industry, footwear and mechanical rubber products.

n-Octyltriethoxysilane: Guide

Octyltriethoxysilane is a functional silane with an octyl group and a triethoxy group. Similar to Silane Z-6341 , OCTEO<strong>Potential Applications of n-octyltriethoxysilane.

n-octyltriethoxysilane can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigment, ormineral fillers),When diluted with an appropiate 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.
