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.

It reduces viscosity in formulations while contributing to network formation during cure, giving formulators control over both processability and final film properties in various industrial applications.

In UV-curable coatings and inks, HDDA lowers formulation viscosity without adding non-reactive solvent, supporting high-speed printing and packaging line requirements for modern manufacturing processes.

Adhesive and sealant manufacturers use it to tune crosslink density, balancing flexibility and cohesive strength in pressure-sensitive and structural formulations across the chemical sector.

Radiation-curable flooring, wood, and industrial coatings rely on HDDA to achieve hard, scratch-resistant surfaces with fast cure response, ensuring high durability and efficient production cycles.

In polymer synthesis, it functions as a crosslinking agent for hydrogels and specialty polymer networks where controlled mesh structure is required for specific technical performance standards.

HDDA is supplied as a low-viscosity liquid, typically with inhibitor added to prevent premature polymerization during storage and transport, maintaining product stability for long-term use.

Technical and industrial grades are the standard commercial offering, with purity specifications commonly at 90% minimum. Bulk, drum, and IBC packaging are the typical supply formats for buyers.
