CAS Number
84170-27-4
What is 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.
Where is Ethoxylated hexanediol diacrylate used?
- UV-curable coatings: reactive diluent that lowers viscosity without sacrificing cure speed or film hardness
- Wood, plastic and metal finishing
- Adhesives and sealants: builds crosslink density and cohesive strength
- Pressure-sensitive and structural systems
- Printing and packaging inks: fast cure response under UV/EB exposure
- Flexible and rigid substrates in high-throughput production
- Polymer and resin manufacturing: building block for controlled flexibility and precise crosslink architecture
Good to know: Its ethoxylated backbone reduces skin sensitization potential compared to standard HDDA while maintaining strong crosslinking performance.
Commercial specifications
- Packaging from drums to IBC containers
- Stabilized grades for extended shelf life
