Description

2-[2-[2-(2-Hydroxyethoxy)Ethoxy]Ethoxy]Ethyl Methacrylate is a specialized methacrylate monomer featuring a hydrophilic tetraethylene glycol spacer terminated with a hydroxyl group. This unique structure is critical for creating polymers with enhanced flexibility, hydrophilicity, and biocompatibility. It is an essential building block for advanced material scientists and formulators in industries requiring precise control over polymer properties, such as medical devices, contact lenses, and high-performance coatings.

Application

• Hydrogel Manufacturing: A key monomer for producing soft, water-absorbing hydrogels used in contact lenses, wound dressings, and drug delivery systems.
• Biomedical Polymers: Used to synthesize biocompatible polymers for medical device coatings, tissue engineering scaffolds, and implantable materials.
• UV/EB Curable Systems: Serves as a reactive diluent and crosslinker in ultraviolet (UV) or electron beam (EB) curable resins for inks, coatings, and adhesives, improving flexibility and adhesion.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify the tack, peel strength, and moisture resistance of acrylic-based adhesive formulations.
• Surface Modifiers & Additives: Used to create polymeric surfactants or additives that improve the wettability, dispersion, or anti-fog properties of coatings and films.
• Dental Materials: A component in formulations for dental composites and restorative materials, contributing to reduced shrinkage and improved mechanical properties.

Quality Control

Our 2-[2-[2-(2-Hydroxyethoxy)Ethoxy]Ethoxy]Ethyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC and impurity profiling, to ensure high purity and consistency suitable for demanding applications. Certificates of Analysis (COA) detailing specific batch results are provided to guarantee supply reliability and product traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from strong acids, bases, and oxidizing agents. To maintain optimal quality and prevent premature polymerization, it is recommended to store under an inert atmosphere (e.g., nitrogen) and use appropriate inhibitors as supplied.
