Description

1,3,5-Trivinyl-1,3,5-Trimethylcyclotrisilazane is a specialized organosilicon compound featuring a cyclic silazane core with reactive vinyl and methyl substituents. This unique structure makes it a valuable precursor and cross-linking agent for advanced materials, enabling the synthesis of polymers with tailored thermal and mechanical properties. It is primarily used by researchers and manufacturers in the semiconductor, specialty polymer, and advanced ceramics industries for developing high-performance coatings, resins, and inorganic-organic hybrid materials.

Application

• Precursor for Silicon Nitride (Si3N4) and Silicon Carbonitride (SiCN) Ceramics: Used in Polymer-Derived Ceramic (PDC) routes to create high-temperature resistant and oxidation-resistant components.
• Cross-linking Agent in Silicone Polymers: Imparts enhanced thermal stability and mechanical strength to silicone rubbers and resins through vinyl-functional cross-linking.
• Surface Modification and Coupling Agent: Functionalizes inorganic fillers (e.g., silica, metals) to improve compatibility and dispersion in organic polymer matrices.
• Synthesis of Dendrimers and Hyperbranched Polymers: Serves as a core or branching unit due to its trifunctional, cyclic architecture.
• Thin Film Deposition (CVD/ALD): Acts as a volatile silicon-nitrogen source for depositing silicon nitride or silicon carbonitride thin films in microelectronics.
• Flame Retardant Additive: Incorporated into polymers to enhance char formation and thermal stability, improving fire resistance.
• Lithography and Photoresist Materials: Utilized in the formulation of advanced photoresists for semiconductor patterning due to its reactive vinyl groups.

Quality Control

Our 1,3,5-Trivinyl-1,3,5-Trimethylcyclotrisilazane is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific batch results are provided and can be tailored to meet customer-specific requirements or research-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from heat, sparks, and open flame.
