Description

Diethoxydivinylsilane is a versatile organosilicon compound characterized by its reactive vinyl and ethoxy functional groups. This dual functionality makes it a valuable cross-linking agent and precursor in the synthesis of advanced silicone polymers and hybrid organic-inorganic materials. It is essential for manufacturers in the silicone elastomer, adhesive, and specialty coatings industries seeking to enhance material properties such as thermal stability, mechanical strength, and adhesion.

Application

• Cross-linking agent in the production of high-performance silicone rubbers and room-temperature vulcanizing (RTV) silicones.
• Key monomer for synthesizing vinyl-functional silicone resins and polymers used in release coatings and pressure-sensitive adhesives.
• Surface modification reagent for introducing vinyl groups onto inorganic substrates like silica, glass, or metals to improve composite compatibility.
• Precursor in sol-gel chemistry for creating hybrid organic-inorganic materials with tailored optical or mechanical properties.
• Intermediate in the manufacture of specialty silanes for the electronics and photonics sectors.
• Adhesion promoter in formulations for primers and coatings where enhanced bonding to diverse substrates is required.

Quality Control

Our Diethoxydivinylsilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards suitable for demanding industrial and research applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

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, the container 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.
