jiajiguisuanna - Introduction
Sodium methyl silicate 30% product is colorless or light yellow transparent liquid, pH ≥ 13, specific gravity 1.10-1.30. No pungent odor, non-combustible, miscible with water, no pollution to the environment. Sodium methylsilicate is a one-component curing synthetic polymer waterproofing agent material. Its mechanism is to generate methylsilanol under the action of water and carbon dioxide, which further combines and chemically reacts with building materials to generate insoluble waterproof polymer compound film. This kind of membrane has the advantages of waterproof, anti-seepage, moisture-proof, anti-rust, anti-aging, anti-pollution, and air permeability. And has excellent weather resistance and durability, no corrosion on steel bars.

jiajiguisuanna - Reference Information
| performance and characteristics | sodium methyl silicate is a one-component curing type synthetic polymer waterproofing agent material, the main component is methyl silicate. Its efficient waterproof mechanism is under the action of water and carbon dioxide, the formation of methyl silicate alcohol, methyl silicate alcohol further combined with building materials and chemical reaction, A layer of several molecular thick insoluble waterproof polymer compound and a network of silicone resin film are formed on the surface and inside of the structural material. The resin film has the advantages of waterproof, anti-seepage, moisture-proof, anti-rust, anti-aging, anti-pollution, air permeability and the like, so it can be widely used in the fields of mud mortar, reinforced concrete, waterproof coating and the like. The treatment of wood, fiberboard, paper and the like with dilute sodium methylsilicate solution after neutralization by aluminum sulfate or aluminum nitrate can play the role of hydrophobicity, corrosion resistance and strength improvement. |
| method of use | 1. Clean the surface of the substrate before use, and fill it with putty or cement slurry if there is any crack. 2. Before construction, the surface of the substrate may be slightly wetted for absorption. 3. Preparation of silicon water: Silicon water was prepared according to the volume ratio of silicone water repellent: Water = 1:12-16. 4. Surface spraying: clean up the base layer, check and repair the cracks, and ensure that the silicon water can be directly sprayed after being clean and firm, no longer water absorption, so repeated spraying 3-4 times, no gap in the middle, the deeper the penetration, the better the waterproof effect. (1kg waterproof agent can be sprayed on nearly 20 square meters) 5. Waterproof mortar: ordinary Portland cement with grade greater than or equal to 425# and medium sand with mud content less than 3%, according to Ash: sand = 1:2.5-3, directly mixed with prepared Silicon water to obtain waterproof mortar, mixed evenly and layered construction, the first pass is 1cm thick, after solidification and hardening of the coating, do the second time, 1cm in thickness, To repeatedly smooth compaction, Yin and Yang angle to be processed into a circular arc, each layer to 1cm thick, waterproof mortar to normal maintenance. 6, can be used to soak, spray or brush and other methods with a wipe, sponge, brush, drum and sprayer construction. It may also be incorporated into concrete for use. 7. After brushing, the treated surface was allowed to dry naturally, and the surface was not dried before painting for the second time. Such as the use of stone, ceramic tile surface protection treatment, 5~10min after construction with soft cloth to erase excess liquid, not stained with water maintenance at least 24h. 8. Theoretical consumption after dilution: 10~30m2/L for all kinds of stone, 5~8m2/L for brick and tile, 5~10m2/L for clean water wall and floor tile. |
| note | ★This product is alkaline, is strictly prohibited from direct contact with the skin, such as contact, the application of large amounts of water rinse. The basicity disappeared after drying of the coated surface, which is harmless to human body. ★For the old wall surfaces with long mildew or oil stain, the mildew spots or oil stain should be thoroughly removed and the surface should be dried before treatment. ★This product will react slowly with carbon dioxide in the air, therefore, when not in use, the package should be covered tightly. |
