DESCRIPTION:
Methyl Siliconate serves as the active ingredient in water repellent treatments for external and internal masonry surfaces.
Methyl Siliconate is consume in use and it is expected that no residual unreacted material will be present in the final treated articles.
Methyl Siliconate is developed to impart water repellency to a wide variety of natural stone and masonry surfaces.
Methyl Siliconate reacts with carbon dioxide in the air to form an insoluble repellent surface and reduce water absorption.
Methyl Siliconate is an aqueous solution of water dilutable having slightly yellowish appearance used for the impregnation of mineral construction materials to make them water-repellent without significantly reducing water vapor permeability.
Methyl Siliconate provides its water repellent properties by reaction with atmospheric carbon dioxide.
Methyl Siliconate is a common chemical substance, which is often used in solid form.
Methyl Siliconate needs to be diluted with water when it is used.
Methyl Siliconate can be used for stone and bricks, ceramics, cement mortar, perlite, gypsum and fiber gypsum board, and other materials, especially porous materials.
Methyl Siliconate can produce surface waterproof and reduce moisture absorption.
Methyl Siliconate is permeable and absorbable and can maintain the natural appearance of the substrate without changing the original color and appearance of the substrate.
Methyl Siliconate can react with carbon dioxide in the air or other acidic compounds to form a surface layer on the substrate.
The insoluble mesh waterproof and breathable membrane has excellent waterproof effect and anti-seepage, moisture-proof, dust-proof, anti-aging, anti-pollution, and other advantages.
Methyl Siliconate prevents moisture from being absorbed into the substrate, thereby reducing the peeling caused by freeze-thaw and weathering, and increasing the life of the substrate.
The most important thing is to be simple and easy to operate in terms of construction.
Before construction, clean the surface of the substrate.
If there are cracks, fill Methyl Siliconate with putty or cement slurry, and then slightly moisten the surface of the substrate for absorption, and the entire project is cost-effective and resistant.
Abrasion, scrubbing resistance, high and low-temperature resistance, Methyl Siliconate can be seen that its performance is superior.
Methyl Siliconate reacts with carbon dioxide in the air to form an insoluble repellent surface and reduce water absorption within 24 hours.
Methyl Siliconate is suitable for the surface of natural stone, like sandstone, limestone, and red brick, gray brick, granite, ceramics etc.
Methyl Siliconate is not suitable for polished or glazed surfaces.

HOW TO USE:
Methyl Siliconate is diluted to a concentration of 3 percent solids or less prior to application.
To prepare a 3 percent solution, mix one gallon (3.78 liters) of Methyl Siliconate, as supplied, with 13 gallons (49.2 liters) of water.
Do not use concentrations higher than 3 percent solids unless prior testing indicates a necessity.
For formulations aimed at being applied for wood impregnation, Methyl Siliconate can be diluted in water to reach a concentration of 5% to 10% solid content.
The use of higher concentrations than required may result in the formation of a white residue on the surface.
Users should test the concentration to be applied on the substrate prior to use.
After application of the silicone solution, allow the treated surface to dry for at least 24 hours to develop maximum water repellency.
This interval may be shortened somewhat by forcedrying at temperatures up to 175°C (350°F).
While this removes the water quickly, time must be allowed for the curing reaction between Methyl Siliconate Siliconate and the surface being treated.
Carbon dioxide streams do not appear to reduce the cure time appreciably.
APPLICATION:
-for concrete, asbestos, gypsum, ceramic, porcelain
-in the production of waterproof papers and leather;
-in the production of water-resistant fabrics;
-by volumetric method in the manufacture of paving tiles, slabs, curbs, fences of different silicate materials;
-as plasticizer in the preparation of plaster, lime and cement solutions;
-as an air involving admixture in the preparation of cement solution
USES:
-Metal manufacture: binding agent in the manufacture of ceramic molds for precision core-mold casting; manufacture of rods exposed to high temperatures; manufactureof non-stick paints;
