Cyclohexanone peroxide is widely used as a curing agent in the polymer industry, particularly for unsaturated polyester resins. It plays a critical role in the production of fiberglass-reinforced plastics, which are used in automotive parts, construction materials, and marine applications. Additionally, it serves as a cross-linking agent in the manufacture of coatings, adhesives, and composite materials, enhancing their durability and mechanical properties. In the electronics industry, it is utilized in the encapsulation of components to provide insulation and protection. Its ability to initiate polymerization reactions makes it valuable in various industrial processes where strong, stable materials are required.
