Features and Properties


  • 2-Octyl Acrylate (2OA) is made from non-edible raw material.
  • It exhibits significantly lower skin irritation compared to 2-Ethylhexyl Acrylate (2EHA), even though both products have the same molecular weight. As a result, 2OA enhances operators’ safety.
  • 2OA can serve as a suitable replacement for 2EHA due to its similar reactivity as a monomer.
  • 2OA has unique properties that distinguishes it from conventional monomers and can be applied to a wide range of applications.


Polymerization and adhesiveness of 2OA are comparable to conventional monomers.
