Description

Ethylene Diacrylate CAS NO 2274-11-5 is a bifunctional acrylate ester monomer characterized by its two reactive vinyl groups. This compound is a critical building block in polymer chemistry, enabling the formation of cross-linked polymer networks with enhanced mechanical strength, chemical resistance, and thermal stability. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop high-performance, durable products.

Application

• Cross-linking Agent for Polymers: Used to create densely cross-linked networks in acrylic and polyurethane resins, improving hardness and solvent resistance in industrial coatings and inks.
• UV-Curable Systems: A key component in UV-curable coatings, adhesives, and printing plates due to its fast curing rate and ability to form rigid polymer matrices.
• Adhesive Formulations: Imparts strong adhesion and cohesive strength in structural adhesives and pressure-sensitive adhesive (PSA) tapes.
• Dental & Medical Materials: Employed in the synthesis of dental composites and bone cements where biocompatibility and high strength are required.
• Fiber Optic Coatings: Used in coatings for optical fibers to provide protective, durable layers with specific refractive indices.
• Lithographic Printing Plates: Serves as a photopolymerizable component in the production of high-resolution printing plates.
• Reactive Diluent: Functions as a low-viscosity reactive diluent to modify the rheology of resin systems without compromising final properties.
• Hydrogel Synthesis: Utilized in creating superabsorbent polymers and hydrogels for agricultural, sanitary, and biomedical applications.

Quality Control

Our Ethylene Diacrylate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identification by FT-IR, and quantification of key impurities such as inhibitor content (MEHQ), water, and acidity. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your specific application requirements.

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. Due to the presence of a polymerization inhibitor, prolonged storage at elevated temperatures should be avoided.
