Vinyltris(methylethylketoxime)silane is a specific type of silane coupling agent that contains vinyl groups and ketoxime functional groups. It is commonly used as a cross-linking agent in various polymer systems, especially in silicone-based materials.
Here are some key points about vinyltris(methylethylketoxime)silane:
Chemical Structure: The chemical formula of vinyltris(methylethylketoxime)silane is (CH?C(O)N=C(CH?)O)?SiCH=CH?. It contains a vinyl group (CH=CH?) for polymerization and cross-linking, as well as three ketoxime functional groups (C(O)N=C(CH?)O) that can react with hydroxyl groups in polymers.
Cross-Linking Agent: Vinyltris(methylethylketoxime)silane is used as a cross-linking agent in silicone-based materials to improve their mechanical properties, thermal stability, and resistance to environmental factors. The vinyl group can undergo addition reactions to form cross-links between polymer chains, enhancing the material's strength and durability.
Adhesion Promoter: As a silane coupling agent, vinyltris(methylethylketoxime)silane can also act as an adhesion promoter between inorganic substrates (such as glass, metal, or ceramics) and organic polymers. The ketoxime functional groups can form bonds with the substrate surface, while the vinyl group can react with the polymer matrix, improving the adhesion between the two materials.
Applications: Vinyltris(methylethylketoxime)silane is commonly used in the formulation of silicone sealants, adhesives, coatings, and rubber compounds. It is also used in the production of silicone-based composites, where it helps to enhance the material's performance properties.
Handling Precautions: Like other silane coupling agents, vinyltris(methylethylketoxime)silane should be handled with care due to its reactivity and potential skin and eye irritant properties. Proper safety measures, such as wearing protective equipment and working in a well-ventilated area, should be observed when using this compound.
Overall, vinyltris(methylethylketoxime)silane plays a crucial role in the modification and enhancement of silicone-based materials, providing improved performance and versatility in a variety of applications.
