Description

2-[2-[2-(2-Hydroxyethoxy)Ethoxy]Ethoxy]Ethyl Acrylate is a specialized, multi-functional acrylate monomer featuring a hydrophilic tetraethylene glycol spacer terminated with a hydroxyl group. This unique molecular structure is critical for imparting flexibility, hydrophilicity, and crosslinking sites in advanced polymer formulations. It is essential for industrial R&D and production teams developing high-performance, water-compatible coatings, adhesives, and functional materials where tailored reactivity and physical properties are required.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker to enhance flexibility, adhesion, and hydrophilicity in coatings for plastics, metals, and paper.
• Hydrogel Synthesis: A key monomer for creating hydrophilic, cross-linked polymer networks used in biomedical applications, contact lenses, and wound dressings.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify the tack, peel strength, and moisture resistance of acrylic adhesive tapes and labels.
• Polymer Modification: Used to introduce pendant hydroxyl and polyether chains into polymer backbones, improving compatibility with polar substrates and dyes.
• Dental & Biomedical Resins: Employed in the formulation of biocompatible resins for restorative materials and drug delivery systems due to its polymerizable groups and hydrophilic character.
• Superabsorbent Polymers (SAPs): Functions as a co-monomer to increase the water absorption capacity and rate in hygiene and agricultural products.
• Lithography & Photoresists: Acts as a component in chemical amplification resists for microelectronics fabrication, contributing to desired dissolution properties.
• Surface Modification Agents: Grafied onto surfaces to create permanent, hydrophilic layers that resist protein adsorption and fouling.
