Description

Bis(2-Methacryloxyethyl) Phosphate is a specialized organophosphorus monomer featuring both methacrylate and phosphate ester functionalities. This unique structure makes it a highly effective adhesion promoter and cross-linking agent, particularly for enhancing the bonding of polymers to metal, glass, and mineral substrates. It is essential for formulators in the coatings, dental materials, and advanced composite industries seeking to improve durability and interfacial strength. The compound is supplied to meet the stringent requirements of industrial and research applications.

Application

• Dental Composite Resins: Key monomer for improving adhesion to tooth enamel and dentin, enhancing the longevity of fillings and restorative materials.
• Metal Primers & Adhesion Promoters: Critical component in primers for automotive, aerospace, and industrial coatings to ensure strong, corrosion-resistant bonding to steel, aluminum, and other metals.
• Glass Fiber Sizings: Used in coatings for glass fibers to improve the interfacial adhesion and mechanical properties in fiber-reinforced plastics (FRP) and composites.
• UV-Curable Coatings & Inks: Functions as a reactive diluent and adhesion promoter in radiation-curable systems for plastics, wood, and packaging.
• Bone Cement & Biomedical Polymers: Employed to enhance the bonding of orthopedic cements and implants to bone tissue.
• Flame Retardant Additives: Serves as a reactive intermediate in the synthesis of phosphorus-containing flame retardants for polymers and textiles.

Quality Control

Our Bis(2-Methacryloxyethyl) Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key specifications are provided with every shipment. We support compliance with relevant industry standards for material traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). This material is light-sensitive and easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen or argon) is recommended to preserve stability and prevent polymerization. Keep away from heat, sparks, and open flame.
