Description

Divinyltetramethyldisilazane is a highly reactive organosilicon compound primarily used as a versatile silylating agent and a key monomer in advanced polymer synthesis. Its value lies in its ability to introduce vinyl and dimethylsilyl groups, enabling the creation of specialized silicone polymers and surface modifications. This chemical is essential for manufacturers and R&D teams in the silicone elastomer, specialty coatings, and advanced materials sectors seeking to enhance product performance and develop novel functionalities.

Application

• Silicone Polymer Synthesis: A crucial monomer for producing vinyl-functionalized polysiloxanes and silicone resins, imparting cross-linking sites for improved thermal and mechanical properties.
• Surface Modification & Coupling Agent: Used to modify inorganic fillers (e.g., silica, glass) and surfaces to improve compatibility and adhesion in composite materials and coatings.
• Pharmaceutical & Agrochemical Intermediates: Serves as a protective group agent (silylating agent) in the synthesis of complex organic molecules, facilitating specific reaction pathways.
• Adhesive & Sealant Formulations: Imparts reactivity and enhances the cure characteristics of high-performance silicone-based adhesives and sealants.
• Release Coatings & Molding: Employed in formulations for non-stick release coatings and in the production of silicone molds due to its vinyl functionality.
• Research & Development: A valuable building block in academic and industrial R&D for exploring new organosilicon chemistry and material science applications.

Quality Control

Our Divinyltetramethyldisilazane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results are provided to guarantee compliance with your technical requirements and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
