What is 2-ethylhexyl acrylate?
2-Ethylhexyl acrylate (CAS 103-11-7), abbreviated 2-EHA, is a long-chain acrylic monomer that introduces flexibility and low-temperature performance into polymer systems.
Where is 2-ethylhexyl acrylate used?
- Pressure-sensitive adhesives: primary soft monomer controlling peel strength and tack in tapes, labels and protective films
- Architectural and industrial coatings: lowers glass transition temperature, improving film flexibility and resistance to cracking in exterior applications
- Sealants and elastomeric compounds: elongation and weathering resistance
- Personal care: film-forming polymers for hair fixatives and skin-adhesive formulations
- It copolymerizes readily with harder monomers to balance softness, tack and durability.
Good to know: Inhibited grades typically containing MEHQ support safe storage and transport.
Commercial specifications
- Purity 99%+ standard for polymerization-grade material
- Clear liquid in ISO tank, drum and IBC formats
