Cyclohexanone peroxide is primarily used as a curing agent in the polymer industry, particularly for unsaturated polyester resins. It facilitates the cross-linking process, which enhances the mechanical properties, durability, and chemical resistance of the final product. This makes it valuable in manufacturing composite materials, such as fiberglass-reinforced plastics, used in automotive parts, marine vessels, and construction materials. Additionally, it serves as an initiator in polymerization reactions, aiding in the production of various plastics and coatings. Its role in these processes ensures improved performance and stability of the end products.
