Description

Diethyleneglycol Dimethacrylate is a high-purity difunctional methacrylate monomer, also known as Diethylene Glycol Dimethacrylate (DEGDMA). This versatile crosslinking agent is essential for creating durable, high-performance polymer networks with excellent chemical resistance and mechanical properties. It is a critical raw material for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance and reliability.

Application

• Crosslinking agent in UV-curable inks, coatings, and adhesives for rapid curing and enhanced durability.
• Key monomer for producing optical lenses, dental composites, and biomedical devices requiring high clarity and biocompatibility.
• Modifier for acrylic and polyester resins to improve hardness, solvent resistance, and thermal stability.
• Component in gel coats, fiberglass reinforced plastics (FRP), and casting resins for industrial and marine applications.
• Building block for specialty polymers used in electronics encapsulation and photoresist materials.
• Intermediate in the synthesis of other functional monomers and polymer additives.

Quality Control

Our Diethyleneglycol Dimethacrylate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity verification, to ensure it meets exacting industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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, and open flame. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
