Silicone liquid GKZH 136-157М is low viscosity colorless or pale yellow oligomethylhydridesiloxane polymer.
Silicone compounds dissolve well in aromatic and chlorinated hydrocarbons, easily gelled by the action of amines, amino alcohols, strong acids and alkalis. Silicone water-repellent GKZH 136-157М is insoluble in water and lower alcohols.
Liquid GKZH 136-157М is a water-repellent agent for surface and volumetric treatment of the porous mineral materials like gypsum, cement, ceramics.
Synonyms: Hydrosilicone oil; Hydrogen silicone oil; Methyl H polysiloxane; Polymethyldrosiloxane; Methylhydro-siliconeoil; Poly(methylhydrosiloxane); methyl silicone oil; Methyl Hydrogen Silicone Fluid; methylhydrogensiloxane polymer.

Silicone liquid GKZH 136-157M is usually used in the form of a diluted solution or aqueous emulsion.
During volumetric hydrophobization, the silicone liquid GKZH 136-157 M is added to the gypsum mixing water. To achieve the water absorption reducing effect, about 0.2-0.4% of the liquid from the amount of dry gypsum is sufficient. The addition of water repellent agent in terms of pure silicone is 0.15-0.2% of the gypsum binder. The effectiveness of the hydrophobic additive GKZH 136-157M application depends on the quantitative and qualitative composition of the gypsum mixture, therefore it is always necessary to conduct preliminary tests to determine the optimal amount.
For hydrophobic treatment of surfaces, GKZH 136-157M silicone water-repellent liquid is used after dilution with one or a mixture of several hydrocarbon solvents (white spirit, solvent, acetone or ethyl methyl ketone).
Dilution rate: on 1 liter of silicone liquid GKZH 136-157M - 10 liters of solvent. Diluted water-repellent solutions can be applied by dipping, spraying or brushing. To apply a working hydrophobic solution on the dry, cleaned surface to the termination of absorption, avoiding drips.
Consumption depends on the processed material surface porosity. The average consumption is 0.2-0.4 l/m2. Always test the selected fluid concentration on a small sample of material to determine its suitability.
