Description

3,6,9,12,15,18-Hexaoxaicosane-1,20-Diyl Diacrylate is a high-purity, difunctional acrylate monomer featuring a long, flexible polyethylene glycol (PEG) spacer. This compound matters because its unique structure provides exceptional hydrophilicity, flexibility, and reactivity, making it a critical crosslinking agent and modifier in advanced polymer formulations. It is essential for manufacturers in the photopolymer, specialty adhesive, and biomedical device coating industries who require precise control over material properties such as water absorption, elasticity, and cure kinetics.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker to enhance flexibility, adhesion, and hydrophilicity in coatings for electronics, optical fibers, and overprint varnishes.
• Hydrogel Synthesis: A key monomer for creating highly absorbent, soft, and biocompatible hydrogels used in contact lenses, wound dressings, and drug delivery systems.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify the tack, peel strength, and moisture resistance of acrylic-based adhesives for medical tapes and labels.
• Dental & Biomedical Resins: Used in light-curable resin composites and bone cements to improve mechanical strength and reduce polymerization shrinkage.
• Lithography & Photoresists: Acts as a functional component in photopolymer formulations for microelectronics and 3D printing (stereolithography), contributing to precise patterning.
• Surface Modification: Employed to graft hydrophilic polymer brushes onto surfaces for anti-fouling or lubrication applications in medical devices and sensors.
• Fiber Optic Coatings: Enhances the protective secondary coating on optical fibers, providing essential flexibility and environmental protection.

Quality Control

Our 3,6,9,12,15,18-Hexaoxaicosane-1,20-Diyl Diacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and compliance with relevant industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, inhibitor content, and physical properties is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to prevent polymerization and oxidation. Keep away from heat, sparks, and open flame. For long-term storage, refrigeration is recommended. Allow the container to reach room temperature before opening to prevent moisture condensation.
