Description

2-[2-(2-Hydroxyethoxy)Ethoxy]Ethyl Acrylate is a specialized acrylate monomer featuring a hydrophilic oligo(ethylene glycol) spacer. This unique structure is critical for synthesizing polymers with tailored hydrophilicity, flexibility, and reactivity. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance through precise molecular design.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and crosslinker to formulate low-viscosity, high-performance coatings with excellent adhesion and flexibility.
• Hydrogel Synthesis: Key monomer for creating hydrophilic, water-absorbent networks used in biomedical applications, contact lenses, and wound dressings.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and moisture resistance to acrylic adhesive formulations.
• Polymer Modification: Used to introduce hydrophilic pendant groups onto polymer backbones, improving compatibility and surface properties.
• Dental & Biomedical Materials: Component in resin systems for dental composites and biocompatible polymer matrices.
• Fiber Optic Coatings: Contributes to the protective, flexible primary coatings on optical fibers.
• Lithographic Photoresists: Serves as a functional monomer in photopolymer formulations for microelectronics.
