IOTA 202 high-hydrogen silicone oil enhances the formulation of room-temperature vulcanizing silicone rubber, upgrading the quality of organic silicone crosslinking raw materials.
1. Outstanding advantages of active groups, reliable as a crosslinking agent
The IOTA 202 high-hydrogen silicone oil molecule contains a large number of silicon-hydrogen active groups. Under the platinum catalyst system, it can undergo a silicon-hydrogen addition reaction with vinyl silicone oil, serving as the core crosslinking agent for room-temperature vulcanizing silicone rubber. The product's physical and chemical indicators are controllable, with low volatility, and there are no small molecule by-products during the reaction process. It is suitable for the preparation of liquid silicone rubber, silicone ink, electronic potting sealant, etc.
2. Strong process compatibility, suitable for various synthetic modification scenarios
In addition to the crosslinking use of silicone rubber, IOTA 202 is also an important intermediate for modifying organic silicon synthesis, suitable for the synthesis of polyether-modified silicone oil and alkyl-modified silicone oil, and can also be used for the hydrophobic treatment of dry powder materials. The product has an appropriate viscosity range, good compatibility with various organic silicone raw materials, and is convenient for formulation engineers to adjust the system ratio, adapting to continuous production lines.
3. What conditions should be noted for the storage of IOTA 202?
Answer: It should be stored sealed in a cool and dry environment, away from acids, alkalis, water sources, and avoid contact with metal ions. Water, acids, and alkalis will cause the Si-H bond to hydrolyze, releasing hydrogen gas, which will affect the product's activity and stability. It is recommended to keep the barrel sealed during the storage period and conduct regular inspections of the hydrogen content.
4. How to control the ratio when using IOTA 202 for silicone rubber crosslinking?
Answer: The core is to control the molar ratio of silicon-hydrogen to vinyl. A too low ratio will result in incomplete curing and sticky products; a too high ratio is prone to bubble formation. It is recommended to conduct small-scale tests based on the target hardness and curing temperature, adjust the IOTA 202 addition amount, confirm the curing effect and no bubbles before scaling up production.
