High-hydrogen silicone oil. This product can be cross-linked to form a film at low temperatures under the action of metal salt catalysts. It forms a waterproof film on the surface of various substances. It can be used as gypsum, fabric, glass, ceramics, paper, leather, metal, cement, Waterproofing agent for various materials such as marble, especially for fabrics.
The methyl hydrogen-containing silicone oil emulsion is shared with the methyl hydroxy silicone oil emulsion, which is waterproof and can maintain the breathability of the fabric, and can improve the tear strength, friction strength and stain resistance of the fabric, and improve the feel and stitching performance of the fabric. In addition, it is used as a release and release agent for paper.
Its molecular formula is:
(CH3) 3Si0 [(CH3) (H) Si0] nSi (CH3) 3

Performance and use
1. Special materials for anti-fouling and anti-fouling (liquid A, B) of building ceramics.
2. Moisture-proof and hydrophobic treatment of natural stone, marble, polished brick and building substrate.
3. The special water-repellent agent for waterproof type gypsum board, gypsum board, gypsum block and other products, the water absorption rate is less than 10%, which conforms to national standards.
4. Synthesis of various modified silicone oils, such as the synthesis of polyether silicone oil, is a necessary material for polyurethane foam stabilizer, paint flow agent, silicone fabric finishing agent, and hydrophilic silicone oil.
5. Waterproofing and softening agents for natural and synthetic fiber fabrics, silk and leather, such as for soft finishing of various fibers such as cotton, linen, silk, acrylic, polyester, etc., mainly using hydrogen-containing silicone oil emulsions or hydrogen-containing emulsions and The mode of hydroxy silicone oil emulsion.
6, paper waterproof and anti-adhesive, glass fiber waterproof softener.
7. It is used for moisture-proof and hydrophobic treatment of dry powder fire extinguishing agent, electrical grade magnesium oxide powder, calcium carbonate and other dry powder materials.
8. Anti-yellowing agent for high-temperature vulcanized silicone rubber. Additive silicone rubber products are used as cross-linking agents, and can also be used to dilute silicone rubber inks.
