Ⅲ. Features and Applications
The higher the viscosity of this product, the lower the vinyl content; conversely, the lower the viscosity, the higher the vinyl content. The vinyl groups at both ends exhibit high reactivity, allowing a rapid addition reaction with hydrogen silicone fluid (in the presence of a catalyst), as well as participation in various other reactions.
It serves as the base material for the production of high-temperature vulcanized (HTV) silicone rubber, which is compounded with crosslinkers, reinforcing agents, colorants, structure control agents, and anti-aging agents to prepare HTV silicone rubber compound. It is also used in the production of liquid silicone rubber and serves as the primary material for injection-molded silicone rubber. Additionally, this product can react with various organic materials such as polyurethanes and acrylics to formulate new materials with improved performance (weatherability, anti-aging, UV resistance, enhanced toughness, etc.), such as coatings. It serves as a key raw material for manufacturing various coatings and modified silicone oils.
Ⅳ. Packaging and Storage
- Packaging: This product is sealed in a clean and dry inner plastic-coated iron drums or plastic drums.
- Transportation: During transportation, exposure to sunlight and rain should be prevented. Transport it as non-hazardous goods.
- Storage: Store in a well-ventilated cool and dry place with no contact with harmful substances such as acid and alkali. The shelf life is one year, beyond which, re-test the product according to specifications. It may remain usable if it still meets the requirements.
