Hydrogen-containing silicone oil has excellent hydrophobicity and is suitable for many occasions such as surface treatment of glass, metal, fiber, and powder. This product acts as a catalyst of metal salts, can be cross-linked to form a film at low temperature, and forms a water-release film on the surface of various substances. It can be used as a waterproof agent for various materials such as fabrics, glass, ceramics, paper, leather, metal, cement, and marble. , especially the waterproofing of fabrics.
Hydroxyl silicone oil and hydrogen-containing silicone oil are polymerization reactions between the two polyoxyalkylene monomers. After they are cross-linked, the hydroxyl end loses water and forms a three-dimensional cross-linked insoluble macromolecule, which will greatly improve the hydrophobicity. If you only consider using It is better to use hydrogen-containing silicone oil to reduce the hydrophilic polar part of the hydroxyl group. It is better to use metal catalyst directly. If the budget is sufficient for high cross-linking degree, platinum inorganic acid solution can be used directly. For low cross-linking degree and soft film formation, dibutyltin dilaurate or dibutyltin dilaurate can be used. Please refer to the dilute sulfuric acid electrolyte of beryllium chloride as appropriate.
The combination of methyl hydrogen silicone oil emulsion and methyl hydroxy silicone oil emulsion can waterproof and maintain the air permeability of the fabric, improve the tear strength, friction strength and stain resistance of the fabric, and improve the hand feeling and seaming performance of the fabric. In addition, it is used as a release agent and crosslinking agent for paper
1. Solid silicone rubber - as bridging agent, anti-yellowing agent and coupling agent in high temperature mixing silicone rubber (HTV)
2. As a cross-linking agent for addition-type liquid silicone rubber, Si-C bonds are formed under the catalysis of PT
3. Used as waterproofing agent (water-repellent agent, water-repellent agent) in waterproof clothing and waterproof gypsum board. Under the action of metal salt catalyst, it can be cross-linked to form a film at low temperature, forming a waterproof film on the surface
4. The surface treatment of MgO (electrical grade MgO) plays an insulating role
5. In the textile and garment industries, it can be used as a softener, water repellent, hand feel improver, sewing thread lubrication, chemical fiber spinneret lubrication, and clothing lining aid, etc.
