Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Reaction Products With Aluminum sec-Butoxide is a specialized organoaluminum siloxane compound, CAS 128446-46-8, designed for advanced material synthesis. This product is valued for its unique reactivity profile, combining the properties of hydroxy-terminated polydimethylsiloxane (PDMS) with an aluminum alkoxide. It serves as a critical precursor or catalyst component for B2B clients requiring high-performance materials with enhanced thermal stability, adhesion, or cross-linking characteristics. Key industries that utilize this chemical include advanced polymer manufacturing, specialty coatings, and high-temperature resistant sealants.

Application

• As a coupling agent or adhesion promoter in high-performance silicone rubber and resin formulations.
• As a catalyst or co-catalyst in condensation cure systems for RTV (Room Temperature Vulcanizing) silicones.
• As a key intermediate in the synthesis of aluminum-containing siloxane polymers for heat-resistant coatings and encapsulants.
• In the modification of surface properties for fillers and pigments to improve dispersion in silicone matrices.
• For developing specialized release coatings and anti-foaming agents in industrial processes.
• In the research and development of novel hybrid organic-inorganic materials (ORMOSILs).

Quality Control

Our Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Reaction Products With Aluminum sec-Butoxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent composition, reactivity, and performance. Key parameters monitored include aluminum content, hydroxyl value, viscosity, and residual solvents. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and may react with strong bases. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and ensure shelf-life stability. Keep away from incompatible materials such as strong alkalis and oxidizing agents.
