Description

2-(2-Methoxyethoxy)Ethyl Methacrylate is a specialized methacrylate monomer featuring a hydrophilic oligo(ethylene glycol) side chain. This unique structure is critical for imparting flexibility, hydrophilicity, and enhanced biocompatibility to polymer chains. It is an essential building block for advanced material scientists and formulators in sectors demanding tailored polymer properties. Key industries that utilize this monomer include specialty coatings, biomedical hydrogels, and advanced adhesive technologies.

Application

• Hydrogel Synthesis: A key monomer for creating soft, water-absorbent hydrogels used in contact lenses, wound dressings, and drug delivery systems.
• Biocompatible Coatings: Used to formulate hydrophilic and protein-resistant coatings for medical devices and implants to improve biocompatibility.
• UV/EB Curable Systems: Serves as a reactive diluent and modifier in ultraviolet (UV) or electron beam (EB) curable inks, coatings, and adhesives to adjust viscosity and flexibility.
• Pressure-Sensitive Adhesives (PSAs): Incorporated into acrylic PSA formulations to enhance tack, adhesion to low-energy surfaces, and moisture resistance.
• Specialty Acrylic Resins: Used in the production of water-soluble or dispersible acrylic resins for industrial and architectural coatings.
• Lithographic Printing Plates: A component in photopolymer formulations for high-resolution printing plates due to its reactivity and solubility characteristics.

Quality Control

Our 2-(2-Methoxyethoxy)Ethyl Methacrylate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC/HPLC, purity verification, and control of critical impurities like inhibitors and water content. We provide Certificates of Analysis (COA) with every shipment to ensure traceability and compliance with your technical specifications. For customers with specific regulatory needs, we can support documentation for applications under cGMP, ISO, or REACH frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. This product is light-sensitive (store away from light) and is compatible with strong acids and organic solvents, but appropriate chemical segregation practices should be followed. To maintain optimal quality and prevent premature polymerization, ensure the inhibitor content (typically MEHQ) is maintained as specified.
