Description

7-[(Tributylstannyl)Oxy]-Tetrasiloxane-1,1,1,3,3,5,5,7,7-Nonol is a specialized organotin-functionalized siloxane compound, representing a high-value intermediate in advanced materials synthesis. Its unique hybrid structure combines the catalytic and stabilizing properties of organotin with the flexibility and thermal stability of a siloxane backbone. This compound is essential for researchers and manufacturers developing next-generation silicone polymers, high-performance release coatings, and specialized catalysts.

Application

• Crosslinking Agent & Catalyst: Serves as a reactive intermediate or catalyst in the synthesis of specialty silicone resins and elastomers, particularly for high-temperature applications.
• Polymer Modification: Used to introduce organotin functionalities into polymer chains to impart specific properties like biocidal activity, UV stabilization, or improved thermal characteristics.
• Release Coatings: A key precursor in the formulation of high-performance, platinum-catalyst-free silicone release coatings for labels and adhesive tapes.
• Adhesives & Sealants: Functions as an adhesion promoter and stabilizer in advanced silicone-based adhesive and sealant formulations.
• Material Science R&D: Employed in academic and industrial research for developing novel hybrid organic-inorganic materials (ORMOSILs).
• Surface Treatment: Can be used to modify surface properties of materials, enhancing hydrophobicity or creating specific reactive sites.
