Description ST-40 is a new weather-resistant silicone material with strong permeability. It can penetrate into porous materials for deep modification, reshape the surface microstructure of the material, and even change the surface light reflection characteristics. This product is suitable for color enhance, polishing, repairing and renovating colored stones to enhance the aesthetic value of the stone and also gives the stone waterproof and anti-fouling functions. Compared with film-forming materials, the treatment effect of permeable materials is more natural and can better maintain the natural beauty of the stone. Attention 1. This product should be packaged in well-sealed HDPE or galvanized iron drums and stored in a cool, dark and dry place. Fireworks are prohibited in the use area and children are prohibited from touching it. 2. Before large-area construction, please be sure to conduct a small-area test. 3. Please wear special protective gloves, goggles and masks when using this product. This product generally must be diluted with a solvent before use, and the formula depends on the terminal application scenario. 4. After dilution, use a clean brush or soft cloth to dip in enough liquid and apply it evenly on the surface of the substrate to ensure that the substrate is fully absorbed, and then wipe off the remaining liquid on the surface. 5. For substrates that have been surface modified or contaminated, the use effect may be affected. 6. In order to improve the use effect, all utensils and raw materials should be kept dry and clean during preparation, and contact with moisture should be reduced. 7. After construction, ventilate at room temperature for more than 24 hours. The base material is prohibited from contacting water before the protective effect is produced.

Organosilane/siloxane molecules have both hydrophobic groups and reactive functional groups. Natural stone is mainly composed of minerals such as quartz, feldspar, and calcite. It is very suitable for surface modification with organosilane/siloxane. The reactive functional groups react with the inorganic substrate and combine together. At the same time, the hydrophobic groups face the outside world, preventing water molecules from approaching, making the surface of the material water-repellent like lotus leaves.

Appearance: colorless to light yellow transparent liquid Specific gravity: 1.18 g/mL Solid content: 52 wt% Diluent: pure water Additional dosage: 30~50 times dilution Chemical properties: alkaline silica sol Function: building waterproofing, anti-corrosion This product is a water-soluble silicone resin solution synthesized by hydrolysis and condensation of various organosiloxanes, and is alkaline. The specific functional groups in the molecular structure form a stable chemical bond with the -OH on the surface of the substrate to modify the substrate. At the same time, it can also condense to form a nano-hydrophobic structure, so that the surface of the material produces a super-hydrophobic effect. The product has high reactivity and strong versatility. It is particularly suitable for hydrophobic treatment of porous inorganic substrates, reducing water absorption, while maintaining the original color, breathability and appearance of the material. The substrate treated with this product has self-cleaning, anti-fouling, moisture-proof and other functions on the surface, which effectively improves the beauty of the building and extends the life of the structure. Suitable for the maintenance and treatment of natural stones such as granite, marble, sandstone, etc., to prevent the stones from becoming diseased; impregnation of highly water-absorbent inorganic aggregates: such as perlite boards, roof tiles, cement bricks, high-rise building light brick facings, asbestos, inorganic fabrics, thermal insulation materials, etc., to make them have significant waterproof and moisture-proof effects;
