Description

6,6-Divinyl-2,5,7,10-Tetraoxa-6-Silaundecane is a specialized organosilicon compound, specifically a vinyl-functionalized silane derivative. This chemical is a crucial intermediate and cross-linking agent valued for its ability to introduce reactive vinyl groups into polymer matrices and inorganic surfaces. It is primarily sought after by manufacturers in the advanced materials, specialty polymers, and electronics sectors for applications requiring enhanced adhesion, surface modification, and the creation of hybrid organic-inorganic networks.

Application

• As a key cross-linking agent in the synthesis of silicone resins and high-performance elastomers.
• As a surface modification agent for silica, glass, and other inorganic fillers to improve compatibility with organic polymer matrices.
• As a reactive monomer in the production of adhesion promoters and primers for coatings, sealants, and adhesives.
• In the formulation of release coatings and low-surface-energy materials.
• As a building block for dendrimers and hyperbranched polymers with tailored properties.
• In electronic encapsulants and potting compounds to enhance moisture resistance and mechanical stability.
• For research and development of novel hybrid organic-inorganic materials (ORMOSILs).
