Description

2-[(Diethoxyphosphinyl)Oxy]Ethyl Methacrylate is a specialized organophosphorus monomer that combines a methacrylate group with a phosphonate ester functionality. This unique structure makes it a critical intermediate for synthesizing polymers with enhanced adhesion, flame retardancy, and surface-modifying properties. It is essential for manufacturers in the advanced materials, coatings, and specialty chemical sectors seeking to develop high-performance products.

Application

• As a key monomer for synthesizing flame-retardant polymers and coatings for electronics, textiles, and construction materials.
• In the production of dental and biomedical adhesives and composites, where improved bonding to hard tissues is required.
• As a surface-modifying agent or crosslinker in high-performance industrial coatings to enhance corrosion resistance and adhesion to metal substrates.
• For the development of ion-exchange resins and chelating polymers used in water treatment and metal recovery processes.
• In the synthesis of adhesion promoters for glass, metal, and mineral-filled composite materials.
• As a reactive intermediate in the research and development of novel photocurable resins for 3D printing and optical applications.

Quality Control

Our 2-[(Diethoxyphosphinyl)Oxy]Ethyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature and reactive methacrylate group, prolonged exposure to light or elevated temperatures should be avoided to maintain product stability.
