Description

9-[Di(Allyloxy)Methyl]-4,4,14,14-Tetraethoxy-3,8,10,15-Tetraoxa-4,14-Disilaheptadecane is a specialized organosilicon compound featuring a unique molecular architecture with multiple alkoxy and allyloxy functional groups. This structure makes it a valuable crosslinking agent and reactive intermediate for synthesizing advanced polymeric materials with tailored properties. It is primarily utilized in the production of high-performance silicones, resins, and coatings where thermal stability, flexibility, and adhesion are critical. Industries such as advanced electronics, specialty adhesives, and release coatings rely on this chemical for formulating next-generation products.

Application

• Silicone Crosslinking Agent: A key component in the synthesis of room-temperature vulcanizing (RTV) silicones and high-consistency rubber (HCR) for seals, gaskets, and flexible molds.
• Polymer Modification: Used as a reactive monomer or modifier to introduce silicon-based functionality into organic polymer backbones, enhancing thermal and chemical resistance.
• Adhesive & Sealant Formulations: Imparts improved adhesion, durability, and moisture resistance in high-performance industrial and construction adhesives.
• Release Coating Precursor: Serves as a building block for silicone-based release coatings used in labels, tapes, and packaging materials.
• Electronic Encapsulants: Employed in the formulation of protective gels and potting compounds for electronic components due to its potential for creating stable, insulating networks.
• Surface Treatment Agent: Can be used to modify surface properties of fillers (like silica) or substrates to improve compatibility and dispersion in composite materials.
