Description

Cyclohexanone Peroxide CAS NO 78-18-2 is a powerful organic peroxide primarily used as a polymerization initiator and cross-linking agent. Its high reactivity makes it a critical component for initiating free-radical reactions in the production of polymers and resins. This compound is essential for manufacturers in the plastics, coatings, and composite materials industries seeking efficient curing and cross-linking solutions.

Application

• Polymerization Initiator: Used to initiate the free-radical polymerization of monomers like styrene, vinyl acetate, and acrylics in the production of various plastics and resins.
• Unsaturated Polyester Resin (UPR) Curing: Serves as a key curing agent (hardener) for fiberglass-reinforced plastics (FRP) and sheet molding compounds (SMC).
• Acrylic Resin Production: Employed in the synthesis of acrylic sheets, castings, and adhesives.
• Cross-linking Agent for Elastomers: Facilitates the vulcanization and cross-linking of certain synthetic rubbers to enhance their properties.
• Coatings and Inks: Acts as a drying agent and cross-linker in specific solvent-based coating and printing ink formulations.
• Wood & Flooring Finishes: Used in the curing process for high-performance wood coatings and floor finishes.
• Chemical Synthesis: Functions as an oxidizing agent in select organic synthesis reactions.

Quality Control

Our Cyclohexanone Peroxide is manufactured under strict process controls to ensure batch-to-batch consistency and reliability. Quality is verified through comprehensive analytical testing, including assay, active oxygen content, and impurity profile analysis. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. As a strong oxidizer, it must be segregated from combustible materials, reducing agents, acids, and bases. Recommended storage temperature is 15-25°C. Containers must be kept tightly sealed to prevent moisture absorption and decomposition.
