Product Description
This product is a water-soluble silicone resin solution synthesized by hydrolysis and condensation of various organosiloxanes, which 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.

Product advantages:
1. Water-based material, non-toxic and odorless, safe and easy to apply, and reasonable cost.
2. High surface activity, outstanding modification effect, excellent hydrophobic performance.
3. Adopting silicone penetrative material, it has excellent weather resistance and durability.

Scope of application
1.Care and treatment of natural stones such as granite, marble, sandstone, etc., to prevent stone from becoming diseased.
2.Impregnation of highly absorbent inorganic aggregates: such as perlite boards, roof tiles, cement tiles, high-rise building light brick facings, asbestos, inorganic fabrics, thermal insulation materials, etc., to make them have significant waterproof and moisture-proof effects.
3.Waterproof and dampproof of roofs, internal and external walls, bathrooms, kitchens, basements and warehouses, and anti-penetration of reinforced concrete structures.
Material Usage Explanation
1. Waterproofing is generally applied after the building is molded. It is necessary to remove floating ash, oil stains and other foreign matter from the base material surface and repair defects.
2. Please allow the substrate to dry completely before application to get the best results. For substrates that have already been surface-modified or contaminated, the effect may be affected.
3. Mix this product with appropriate dilutions and auxiliary agents in the predetermined ratio, seal and prepare evenly. Before carrying out large-area construction, small-area testing must be carried out.
4. Use brush, paint or spray to apply waterproofing to the substrate surface, making sure the substrate surface is sufficiently moist and absorbent.
5. After painting, leave the paint in a ventilated place at room temperature for 16 to 24 hours (48 hours is best). Do not allow the substrate to come into contact with water before the protective effect is achieved. The reaction time depends on the amount of paint and the environmental temperature.
