In the process of continuous development towards functionality and refinement in numerous industries such as building materials, textile printing and dyeing, rubber processing, and ceramic manufacturing, organic silicon intermediates with high reactive silicon-hydrogen bonds are becoming key raw materials for achieving functions such as waterproofing, anti-fouling, anti-adhesion, and cross-linking modification on the surface of substrates. The products launched by our company, high-hydrogen silicon oil 202, as a high-hydrogen content methyl polysiloxane, thanks to its highly reactive silicon-hydrogen bonds and the property of forming films at low temperatures on various substrate surfaces, demonstrate significant industrial application value in numerous fields such as fabric waterproofing treatment, building material anti-fouling treatment, paper anti-adhesion isolation, silicone rubber cross-linking, and powder hydrophobic modification, providing high-performance functional active intermediate raw materials for customers in various industries.


I. Core Physical and Chemical Characteristics


Product high-hydrogen silicon oil 202 is a colorless transparent liquid with a hydrogen content of no less than 1.55%. At 25 degrees Celsius, its viscosity is 15 to 40 square millimeters per second, its refractive index is 1.390 to 1.410, its density is 0.995 to 1.015 grams per cubic centimeter, and its volatility is no more than 4.00%. This product is a typical fully hydrogen-containing functional silicone oil, with a large number of active silicon-hydrogen bonds in its molecular chain. This characteristic enables it to cross-link into a film at low temperatures under the action of metal salt catalysts, forming a waterproof film with excellent hydrophobic properties on various substrate surfaces. The high hydrogen content gives the product extremely high reactivity and cross-linking density, allowing for ideal treatment effects with a small amount. At the same time, it forms a durable waterproof film on various substrate surfaces, with excellent anti-adhesion properties.


II. Core Reaction Characteristics and Application Value


The application value of product high-hydrogen silicon oil 202 stems from the densely distributed active silicon-hydrogen bonds in its molecular chain. Under the action of metal salt catalysts, these silicon-hydrogen bonds can undergo dehydrogenation condensation reactions with active groups such as hydroxyl groups on the substrate surface, forming a firm hydrophobic film layer on various substrate surfaces; they can also undergo silicon-hydrogen addition reactions with unsaturated compounds, introducing a silicon-oxygen structure into the target molecules or the substrate surface.


In fabric waterproof treatment, when this product is used in combination with methyl hydroxyl silicone oil emulsion, it not only provides excellent waterproof performance to the fabric, but also maintains the breathability of the fabric unaffected, significantly improving the tear strength, friction strength, and anti-fouling performance of the fabric, and improving the hand feel and sewing performance. The optical glass coated with this product not only has high light transmittance but also has excellent anti-mold and anti-humidity properties. In ceramic anti-fouling treatment, the cross-linking film formation characteristic of hydrogen-containing silicone oil is utilized to form a firm hydrophobic and oleophobic anti-fouling layer on the ceramic tile surface, preventing ink, dust, and other contaminants from penetrating and adhering.
