Silane Water Repellent

Technical Data

Application

• SiSiB® WR0412 silicone water repellent coating 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® WR0412 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® WR0412 may be applied to damp surfaces although dry surfaces are preferred to achieve maximum penetration into the substrate.

• SiSiB® WR0412 can be used as a silane surface modifier to generate hydrophobicity and to increase compatibility to organic non polar matrices.

• SiSiB® WR0412 can be used as a component for the manufacture of Ziegler-Natta Catalysts.
