1. The biggest advantage of methyl hydrogen-containing silicone oil is its good waterproof effect. Under the action of metal salt catalysts, it can cross-link to form a film at low temperature, and form a waterproof film on the surface of various substances. It can be used as a waterproof treatment agent for various materials such as fabrics, glass, ceramics, paper, leather, cosmetics (lip balm, etc.), metal, cement, and marble.
I believe that you already have some understanding of low-hydrogen silicone oil in the previous article, so in order to deepen your understanding of low-hydrogen silicone oil, I will bring you some knowledge points about the difference between low-hydrogen silicone oil and high-hydrogen silicone oil. Please refer to it.
In addition to the characteristics of dimethyl silicone oil, low-hydrogen-containing silicone oil can produce addition and crosslinking reactions due to its active hydrogen content. Use its hydrosilylation reaction as an intermediate for the synthesis of modified silicone oil and as a crosslinking agent for addition-type silicone rubber.
High hydrogen-containing silicone oil, under the action of metal salt catalysts, can be cross-linked to form a film at low temperature, forming a waterproof film on the surface of various substances. It can be used as a waterproofing agent for various materials such as fabrics, glass, ceramics, paper, leather, metal, cement, and marble, especially for fabrics. In addition, it is used as a release agent and crosslinking agent for paper. Anti-yellowing agent for high-temperature fluidized silicone rubber, addition-type silicone rubber series products are used as cross-linking agent, and can also be used to dilute silicone rubber ink.
2. The main raw material for hydrosilylation reaction, which can further synthesize a variety of modified silicone oils and be used as a cross-linking agent for addition-type silicone rubber. Using low-hydrogen silicone oil, allyl polyether, and dodecene as main raw materials, the modified silicone oil was synthesized by a solvent-free method. The effects of different catalyst dosage, different activation temperature and activation time, reaction temperature and reaction time on the properties of modified silane oil were studied. Using polyether to activate the catalyst, when the amount of catalyst platinum is 2ppm, the activation temperature is 70-75°C, the activation time is 150min, the reaction temperature is 100°C, and the reaction time is 4h, a polyether and long-chain alkyl co-modified silicone oil with better performance is synthesized. Meanwhile, the structure of the product was characterized by infrared spectroscopy.

Hydrogen-containing silicone oil is non-toxic and tasteless, and has lively active genes. Under the action of a catalyst, it can react with genes such as double bonds and hydroxyl groups. It is the basic raw material for foam stabilizers, defoamers, and water-soluble silicone oils. Not all low-hydrogen silicone oils can produce water-soluble silicone oil polyether modified silicone oil. In the case of improper selection of low-hydrogen silicone oil, there will be problems caused by water-soluble silicone oil polyether modified silicone oil cross-linking and cooling, solidification or non-polymerization reaction. When choosing, we must do experiments first, then carry out pilot tests and finally mass production.
