Applications:

N-Octyltrimethoxysilane (CAS No. 3069-40-7), silane coupling agent KH-831, is an important additive for many applications. Examples are:

KH-831 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 KH-831 treated minerals or pigments are incorporated into polymers, e. G. Polyethylene or polypropylene. Loading levels of 0.5 to 1.5% wt. KH-831 based on the weight of fillers or pigments are typically recommended.

KH-831 silane can also be used to improve the compatibility of mineral fillers or pigments in polyolefins or to ease their dispersion in nonpolar matrices.

KH-831 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.

Packing & storage:

1. 200L PVF steel barrel or 1000L IBC drum

2. Store in a cool, dry place. Avoid light.
