Product Description
Abstract
N-Octyltriethoxysilane (CAS No. 2943-75-1), silane coupling agent SCA-K08E, is a monomeric medium-chain alkylfunctional silane. SCA-K08E is a clear colorless liquid and soluble in common non-polar organic solvents (e. G. Petroleum ether, toluene). However its low volatility and viscosity make SCA-K08E an easy-to-handle additive. During the hydrolysis reaction between water and SCA-K08E a certain amount of ethanol (VOC) is released.

Application
N-Octyltriethoxysilane (CAS No. 2943-75-1), silane coupling agent SCA-K08E, is an important additive for many applications. Examples are:
SCA-K08E silane can be used as a surface modifier to generate hydrophobicity (e. G. On concrete, glass, inorganic pigments, or mineral fillers). The medium-chain alkyl functionality results in unique compound properties when SCA-K08E treated minerals or pigments are incorporated into polymers, e. G. Polyethylene or polypropylene. Loading levels of 0.5 to 1.5% wt. SCA-K08E based on the weight of filler or pigment are typically recommended.
SCA-K08E silane can also be used to improve the compatibility of mineral fillers or pigments in polyolefins or to ease their dispersion in nonpolar matrices.
SCA-K08E silane is a small molecule to allow for deep penetration into the cementitious surface. This material reacts with moisture in the air and in the substrate in the presence of an alkaline or acidic environment to produce hydroxy groups. These hydroxy groups will bond with the substrate and itself to produce a hydrophobic treatment that inhibits water absorption into the substrate. An alkaline environment, such as new concrete, will catalyze the reaction and speed the formation of the hydrophobic surface.
