2-Hydroxyethyl Methacrylate – HISS grade (commonly branded simply as “HEMA-HISS”) is an ultra-high-purity, water-dry monomer engineered for demanding optical, biomedical and 3D-printing applications. Produced by additional vacuum-distillation and inhibitor-stripping steps, it contains ≥ 99.5 % active monomer and no more than 50 ppm of the polymerisation inhibitor MEHQ, yielding exceptionally low colour and acid values. This near-inhibitor-free profile lets formulators achieve faster UV/EB curing, higher molecular-weight polymers and crystal-clear transparency, while the preserved hydroxyl functionality still provides the robust adhesion, flexibility and hydrophilicity that make HEMA indispensable across coatings, hydrogels and dental composites. Because of its reactivity, HEMA-HISS is shipped under nitrogen and should be stored cool, but in return it unlocks premium performance wherever every trace of impurity matters.
