Description

Behenyl Methacrylate is a high molecular weight, long-chain alkyl methacrylate monomer derived from behenyl alcohol. This compound is valued for its ability to impart exceptional hydrophobicity, flexibility, and low-temperature properties to polymer chains. It is primarily sought after by formulators and polymer chemists in the coatings, adhesives, and personal care industries seeking to enhance product performance and durability.

Application

• Coatings & Inks: As a key monomer for producing high-performance acrylic resins used in automotive, industrial, and architectural coatings to improve water resistance, flexibility, and gloss.
• Adhesives & Sealants: Used to modify acrylic pressure-sensitive adhesives (PSAs) and sealants, enhancing tack, peel strength, and low-temperature performance.
• Personal Care & Cosmetics: Serves as a film-forming agent and rheology modifier in nail polishes, hair styling products, and skin care formulations.
• Lubricant & Fuel Additives: Employed as a viscosity index improver and pour point depressant in synthetic lubricants and industrial oils.
• Textile & Leather Finishing: Used in polymer emulsions for fabric and leather coatings to provide softness, water repellency, and durability.
• Plastic Additives: Acts as an internal lubricant and processing aid for PVC and other engineering plastics to improve flow and surface finish.

Quality Control

Our Behenyl Methacrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identity confirmation (IR), and analysis of key impurities like residual monomer and moisture. A detailed Certificate of Analysis (COA) is provided with each shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve purity and prevent polymerization.
