High hydrogen silicone oil
Methyl hydrogen-containing silicone oil emulsion is shared with methyl hydroxy silicone oil emulsion, which can be waterproof and maintain the breathability of the fabric, and 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 an anti-stick separator and cross-linking agent for paper.
Its molecular formula is: (CH3)3Si[(CH3)Si0][(CH3)(H)Si02]ySi(CH3)3

Performance and use
1. Special raw materials for antifouling and anti-fouling of architectural ceramics (A and B liquid).
2. Moisture-proof and hydrophobic treatment of natural stone, marble, polished brick and building substrate.
3. Waterproof paper gypsum board, gypsum waterproof board, gypsum block and other products of special waterproofing agent, water absorption rate is less than 10%, in line with national standards. 4. The synthesis of various modified silicone oils, such as the synthesis of polyether silicone oil, is a necessary material for polyurethane homogenizer, coating flow agent, silicone fabric finishing agent, and hydrophilic silicone oil.
5. Waterproofing agent and softener for natural and synthetic fiber fabrics, silk and leather, such as for the soft finishing of various fibers such as fabric cotton and linen, silk and acrylic, polyester, etc., mainly in the way of hydrogen-containing silicone oil emulsion or hydrogen-containing emulsion and hydroxy silicone oil emulsion.
6. Waterproof and anti-sticking agent for paper, waterproof softener for glass fiber.
7. It is used for moisture-proof and hydrophobic treatment of dry powder materials such as dry powder fire extinguishing agent, electrical-grade magnesium oxide powder, calcium carbonate, etc.
8. Anti-yellow agent for high-temperature vulcanized silicone rubber, plus molding silicone rubber series products used as crosslinking agent, can also be used to dilute silicone rubber ink.
