Description
Siwin-9832 Silane is high purity, undiluted N-octyltriethoxy-silane. 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 hydro-phobic and retain their original appearance. Siwin-9832 Silane can also be used to improve the compatibility of mineral fillers or pigments in polyolefins or to ease their dispersion in non-polar matrices.
Siwin-9832 Silane is a small molecule to allow for deep penetration into the cementitious surface. This material reacts with moisture in the air and n 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.
HOW TO USE
Dilution
Siwin-9832 Silane can be diluted in solvents such as alcohols, chlorinated solvents, aliphatic solvents and low molecular weight cyclic polydimethylsiloxane such as Siwin-D4 Cyclotetrasiloxane before use. Typical dilution levels are 40 percent and 20 percent Siwin-9832 Silane in a solvent.
Blends of the solvents can also be used. The evaporation rate of the diluted material can be modified depending on the type and concentration of the solvent. Select the proper solvent for your application, as some silane/solvent blends may darken the surface. Refer to the manufacturer’s data sheet for proper handling and disposal of solvents.
