1,6-Hexanediol diacrylate

1,6-Hexanediol diacrylate (CAS 13048-33-4), commonly known by its abbreviation HDDA, is a bifunctional acrylate monomer used as a reactive diluent and crosslinker in UV- and radiation-curable systems.

Where is 1,6-Hexanediol diacrylate used?

• UV-curable coatings and inks: lowers formulation viscosity without non-reactive solvent, supporting high-speed printing and packaging lines
• Adhesives and sealants: tunes crosslink density, balancing flexibility and cohesive strength in pressure-sensitive and structural formulations
• Radiation-curable flooring, wood and industrial coatings: hard, scratch-resistant surfaces with fast cure response
• Polymer synthesis: crosslinking agent for hydrogels and specialty polymer networks with controlled mesh structure
• It reduces viscosity in formulations while contributing to network formation during cure.

Commercial specifications

• Purity specifications commonly at 90% minimum
• Bulk, drum, and IBC packaging
