Application of high hydrogen content silicone oil
High-hydrogen silicone oil, as the name suggests, is scientifically known as polymethylhydrosiloxane. It is formed by the polymerization of hydrogen-containing monomers. Due to the presence of reactive hydrogen, this product is versatile and widely used.
Basic characteristics
• Colorless
• Virtually non-toxic
• Forms a durable film after curing
• Curing time and temperature are adjustable
• Effective at a concentration of 0.2%
• Can be diluted with solvents to improve dispersibility
Application areas
• After emulsification and cross-linking treatments, it can be used for moisture-proofing and waterproofing of building materials such as ceramics, marble, and gypsum board.
• After emulsification, it can be compounded with other silicone oil emulsions for waterproofing and smoothing finishing of fabrics.
• Through further hydrosilylation reaction, it can be made into low-hydrogen silicone oil for the synthesis of various modified silicone oils.
• Anti-yellowing treatment during the vulcanization process of silicone rubber.
Detailed Explanation of the Differences Between High-Hydrogen-Content Silicone Oils and Low-Hydrogen-Content Silicone Oils:
High-hydrogen-content silicone oils, under the action of metal salt catalysts, can crosslink at low temperatures to form a waterproof film on the surface of various materials. They can be used as waterproofing agents for various materials such as fabrics, glass, ceramics, paper, leather, metals, cement, and marble, especially for fabrics. Additionally, they are used as anti-sticking release agents and crosslinking agents for paper. They are also used as anti-yellowing agents in high-temperature fluidized silicone rubber, as crosslinking agents in addition-cure silicone rubber products, and for diluting silicone rubber inks.
Low-hydrogen-content silicone oils, in addition to possessing the characteristics of dimethyl silicone oils, can undergo addition and crosslinking reactions due to the presence of active hydrogen. Their hydrosilylation reaction is utilized as an intermediate in the synthesis of modified silicone oils and as a crosslinking agent for addition-cure silicone rubbers.
