Description

20-Hydroxy-3,6,9,12,15,18-Hexaoxaicosyl Acrylate is a specialized polyethylene glycol (PEG) acrylate monomer featuring a long, hydrophilic spacer chain terminated with a reactive acrylate group. This unique structure is engineered to impart hydrophilicity, flexibility, and crosslinking capability to polymer systems. It is a critical building block for formulators seeking to create advanced materials with tailored surface properties and enhanced biocompatibility. Key industries that utilize this monomer include UV-curable coatings, hydrogels for biomedical applications, specialty adhesives, and performance additives.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and modifier to enhance flexibility, adhesion, and hydrophilicity in coatings for electronics, optical fibers, and release papers.
• Hydrogel Synthesis: A key monomer for creating hydrophilic, crosslinked networks used in contact lenses, wound dressings, drug delivery systems, and tissue engineering scaffolds.
• Polymer Modification: Used to graft hydrophilic PEG chains onto polymer backbones (e.g., polyurethanes, polyesters) to improve biocompatibility, reduce protein adsorption, and impart anti-fouling properties.
• Specialty Adhesives & Sealants: Incorporated into formulations to adjust rheology, improve water resistance, and enhance bonding to polar substrates.
• Surface Active Monomers: Employed in the synthesis of surfactants, dispersants, and emulsifiers for advanced material processing.
• Dental Materials: Used in resin-based composites and adhesives to modify hydrophilicity and improve mechanical performance.
