SCA-K08M N-Octyltrimethoxysilane (CAS No. 3069-40-7) CAS NO.3069-40-7

N-Octyltrimethoxysilane (CAS No. 3069-40-7), silane coupling agent SCA-K08M, is an important additive fmany applications. Examples are:

SCA-K08M silane can be used as a surface modifier to generate hydrophobicity (e. G. On concrete, glass, inorganic pigments, SCA-K08M mineral fillers). The medium-chain alkyl functionality results in unique compound properties when SCA-K08M treated minerals pigments are incorporated into polymers, e. G. Polyethylene polypropylene. Loading levels of 0.5 to 1.5% wt. SCA-K08M based on the weight of fillers pigments are typically recommended.
SCA-K08M silane can also be used to improve the compatibility of mineral fillers pigments in polyolefins to ease their dispersion in nonpolar matrices.
SCA-K08M silane is a small molecule to allow fdeep penetration into the cementitious surface. This material reacts with moisture in the air in the substrate in the presence of an alkaline acidic environment to produce hydroxy groups. These hydroxy groups will bond with the substrate itself to produce a hydrophobic treatment that inhibits water absorption into the substrate. An alkaline environment, such as new concrete, will catalyze the reaction speed the formation of the hydrophobic surface.

AbstractN-Octyltrimethoxysilane (CAS No. 3069-40-7), silane coupling agent SCA-K08M, is a monomeric medium-chain alkylfunctional silane. SCA-K08M is a clear colorless liquid soluble in common non-polarganic solvents (e. G. Petroleum ether, toluene). However its low volatility viscosity make SCA-K08M an easy-to-handle additive. During the hydrolysis reaction between water SCA-K08M a certain amount of ethanol (VOC) is released.
