Description

Di(Ethylene Glycol) Ethyl Ether Methacrylate is a high-purity, reactive methacrylate ester monomer featuring a pendant ethoxyethoxy group. This unique structure provides excellent solvency, low volatility, and enhanced flexibility, making it a critical building block for advanced polymer formulations. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to improve product performance, durability, and application properties.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker for formulating low-odor, high-gloss, and flexible coatings and printing inks.
• Acrylic Resin Modification: Used to copolymerize with other acrylates and methacrylates to impart internal plasticization, improving flexibility and adhesion of acrylic polymers.
• Adhesives & Sealants: Enhances the tack, peel strength, and low-temperature performance of pressure-sensitive and structural adhesives.
• Photoresists & Electronic Materials: Serves as a monomer in photopolymerizable compositions for semiconductor and display manufacturing.
• Hydrogel & Contact Lens Materials: Imparts hydrophilicity and flexibility in the synthesis of biocompatible polymers for medical devices.
• Fiber Optic Coatings: Contributes to the protective, flexible primary coatings for optical fibers.
• Automotive & Industrial Coatings: Improves weatherability, chemical resistance, and flow characteristics in solvent-borne and radiation-curable systems.

Quality Control

Our Di(Ethylene Glycol) Ethyl Ether Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, purity, and impurity profile analysis via GC and HPLC, to ensure it meets exacting industry specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. For long-term storage, consider under an inert atmosphere (e.g., nitrogen) to minimize polymerization risk and maintain optimal purity.
