PEG600DA: A key intermediate to promote innovation in functional materials

Recently, with the development of the new materials industry, the functional monomer PEG600DA (polyethylene glycol diacrylate) is gradually entering the market. As a bifunctional photocurable monomer with excellent flexibility, hydrophilicity and reactivity, PEG600DA is widely used in many high-end manufacturing fields such as photocurable coatings, 3D printing resins, hydrogels, electronic materials and biomedical materials.

Chemical structure enables multifunctional applications
PEG600DA is a bifunctional monomer generated by the reaction of polyethylene glycol (PEG) with a molecular weight of about 600 and acrylic acid. Both ends of the molecule contain active acrylic acid groups, and the middle part is a hydrophilic polyethylene glycol segment. This structure gives it:

Good flexibility and film-forming properties, suitable for coatings and adhesives with high flexibility requirements;

Excellent hydrophilicity, excellent performance in water-based systems or hydrogel applications;

Good reactivity, can be copolymerized with a variety of acrylic resins, suitable for UV curing processes

Widely used in UV curing coatings and inks: PEG600DA, as a flexible diluent, can improve the adhesion and flexibility of the coating, while reducing the viscosity of the system and improving the construction performance.

3D printing resin: Its excellent cross-linking performance and toughness are widely used in DLP/SLA printing formulas, which can improve the printing accuracy and strength of the model.

Hydrogel materials: used in medical dressings, drug delivery systems and other fields, the PEG segment provides good biocompatibility and water retention.

Electronic materials: In the fields of photoresists and flexible electronic coatings, PEG600DA can adjust the film-forming properties, combining flexibility and thermal stability.

Functional membrane materials: As a cross-linking monomer, it participates in the preparation of breathable membranes, nanofiltration membranes, etc., to improve the hydrophilicity and mechanical strength of the membrane.

Market prospects and development trends
With the global emphasis on green, low VOC (volatile organic compounds) environmentally friendly materials, the demand for PEG600DA as a solvent-free, low-toxic, customizable functional monomer is continuing to grow. Especially in the fields of renewable materials, biomedical materials, and smart responsive materials, PEG acrylates provide new technical paths.
