Ethoxylated hexanediol diacrylate

Ethoxylated hexanediol diacrylate (CAS 84170-27-4), also referenced commercially as 1,6-Hexanediol ethoxylate diacrylate, is a reactive difunctional monomer used in UV- and radiation-curable systems.

Its ethoxylated backbone reduces skin sensitization potential compared to standard HDDA while maintaining strong crosslinking performance. This distinction directly affects formulation decisions for industrial applications.

In UV-curable coatings, it functions as a reactive diluent that lowers viscosity without sacrificing cure speed or film hardness. This makes it suitable for wood, plastic, and metal finishing processes.

Adhesive and sealant formulators incorporate it to build crosslink density and improve cohesive strength. It is particularly effective in pressure-sensitive and structural systems requiring high performance.

In printing and packaging inks, it supports fast cure response under UV/EB exposure. This enables high-throughput production on both flexible and rigid substrates while maintaining print quality.

Polymer and resin manufacturers use it as a building block where controlled flexibility is required. It allows for precise crosslink architecture in the final network of the polymer system.

Ethoxylated hexanediol diacrylate is supplied as a clear to pale yellow liquid. It is available in technical and industrial grades with inhibitor levels specified to suit storage and processing requirements.

Packaging ranges from drums to IBC containers, with stabilized grades offered for extended shelf life. These options ensure the material remains stable during transport and long-term storage.
