Bis(trimethylsilyl) peroxide is primarily used as a radical initiator in polymerization reactions, particularly in the synthesis of silicone-based polymers. It facilitates the cross-linking of silicone rubbers, enhancing their thermal stability and mechanical properties. This compound is also employed in organic synthesis as a mild oxidizing agent, enabling the introduction of oxygen-containing functional groups into organic molecules. Additionally, it finds applications in surface modification processes, where it helps improve the adhesion and compatibility of materials in coatings and composites. Its role in creating high-performance materials makes it valuable in industries such as automotive, electronics, and construction.
