SiSiB® PC5951 Isobutyltrimethoxysilane

SiSiB® PC5951 is high purity, undiluted iso-butyltriethoxysilane. 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.

SiSiB® PC5951 silane surface modifier is a small molecule to allow for deep penetration into the construction materials (especially concrete and reinforced concrete) surface. This material reacts with moisture in the air and in the substrate in the presence of an alkaline or acidic environment to produce hydroxyl 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.

SiSiB® PC5951 is similar to DowCorning’s Z-2306 silane, Wacker’s IO-TRIMETHOXY, Evonik Degussa’s Dynasylan IBTMO.

Application

SiSiB® PC5951 can be used to render a wide range of surfaces and materials water repellent (e.g.construction materials, fillers), especially concrete and reinforced concrete.

SiSiB® PC5951 alkyl alkoxy silane should be diluted in solvents such as alcohols, chlorinated solvents, aliphatic solvents, and low molecular weight cyclic polydimethylsiloxane, such as SiSiB® CF1040 Fluid before use. Typical dilution levels are 40% and 20% SiSiB® PC5951 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.

Methods of application include airless sprayer, roller and brush. When a brush or roller is used, repeated applications should be made until the surface remains moist for a few minutes. If an airless sprayer is used, application should continue until the substrate is thoroughly saturated. Sprayers should be fitted with solvent resistant hoses and gaskets. A test application is necessary on each surface to be treated to ensure compatibility and the desired water repellent result. Surfaces should be free of standing water, surface dirt, dust, oils, and other contaminants. The formulated SiSiB® PC5951 may be applied to damp surfaces although dry surfaces are preferred to achieve maximum penetration into the substrate.

Like SiSiB® PC 5901 n octyltrimethoxysilane, SiSiB® PC5951 can also be used as a surface modifier to generate hydrophobicity and to increase compatibility to organic non polar matrices.

SiSiB® PC5951 can be used in the production of silane crosslinking formulations.

SiSiB® PC5951 can be used as a component for the manufacture of Ziegler-Natta Catalysts.
