Methyl potassium silicate
Category: Industrial products
Potassium methyl silicate is an alkaline aqueous solution generated by the reaction of potassium hydroxide and methyl silicic acid, which can react with CO2 or other acidic substances in the air to form the active substance polymethyl silicic acid to produce waterproof performance. It is mainly used as a waterproofing agent for minerals.
Basic information
Product name: Potassium methylsilicate
Foreign name: Methyl potassium silicate
Appearance: colorless or light yellow transparent liquid
Total solids content: 40
PH: 13
Product Introduction
Potassium methylsilicate. The product is diluted with water to create surface waterproofness and reduce moisture absorption. It is permeable, absorbable, and maintains the natural appearance of the substrate. It can react with CO2 or other acidic compounds in the air to form an insoluble network waterproof and breathable film on the surface of the substrate, which has excellent waterproof effect and the advantages of anti-seepage, moisture-proof, rust inhibition, anti-aging, anti-pollution, etc., to avoid water inhalation into the substrate, thereby reducing the peeling caused by freeze-thaw and weathering, and increasing the life of the substrate. The product is simple to construct, low cost, long-lasting effect, brush resistance, high and low temperature resistance (-50~150 °C).

Scope of use
The product is mainly used for stone, brick, ceramic, concrete, cement mortar, perlite, gypsum and gypsum board, wood and other surface treatment, can also be used as an additive to water glass.
How to use
1. Clean the surface of the substrate before use, remove the water, dirt and other adhesions in the base area to be treated, if there are cracks to be filled with putty or cement slurry, the surface of the substrate should be flat and solid, and there should be no empty drums, looseness and other phenomena.
2. Before construction, slightly moisten the surface of the substrate for absorption.
3. Dilute to a concentration of 3% or lower when using. If a concentration higher than 3% is required, it must be experimentally verified, and the use of high concentrations will cause white residue to form on the waterproof surface.
4. It can be constructed with rags, sponges, brushes, rollers and sealing spray guns by soaking, spraying or brushing. It can also be incorporated into concrete.
5. After painting, let the treated surface dry naturally, and then paint it a second time before the surface is dry. If used in the surface protection treatment of stone and tiles, wipe off excess liquid with a soft cloth before drying after construction, and maintain it without water for at least 24h.
Notes
1. Before use, a small sample concentration test should be carried out to determine whether the concentration is suitable for your specific use.
2. The product is extremely corrosive, it is strictly forbidden to contact with the skin directly, if accidentally contacted, please rinse with water immediately. In case of contact with eyes, immediately wash with water for 15 min and seek medical attention in time. It can also damage or kill plants, stain or corrode glass, plastic, aluminum and most metals, and special care must be taken when spraying to avoid applying water repellent to nearby plants or objects. When used for home decoration storage, keep out of reach of children. However, the alkalinity of the product disappears after the brush surface is dry, which is harmless to the human body.
3. The preparation of waterproofing agent is too high or too much, after drying, a small amount of white sediment will be formed on the brushed surface, such as rinsing with water or wiping unclean, need to scrape the surface to remove.
4. If the temperature is too low in winter, the product will have a frozen crystal structure, heated to room temperature, the solution will return to transparency, the active ingredients of the product will not be destroyed, and it can continue to be used.
5. It is recommended to wear protective gloves and masks during construction, avoid inhaling the gas generated by the product during open-air construction, and carry out local exhaust when spraying or fogging in a closed environment.
