RJ-OTES is high purity, undiluted n-Octyltriethoxysilane. Treated substrate with RJ-OTES will have good water repellent performance and retain the original appearance. Alkaline environments, such as pouring concrete, will stimulate the reaction and accelerate the formation of hydrophobic layers.

RJ-OTES is also widely used as raw materials of many silicone water repellents.
