1. N-Octyltriethoxysilane (CAS No. 2943-75-1), silane coupling agent NQ-8151 is an important additive for many applications.
2.Can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigments, or mineral fillers).
3. When diluted with an appropriate 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.
KH-350 is high purity, undiluted N-octyltriethoxy-silane. When diluted with an appro-priate 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.
KH-350 can also be used to improve the compatibility of mineral fillers or pigments in polyolefins or to ease their dispersion in nonpolar matrices.
KH-350 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.
