In vivo and in vitro testing of gloves for protection against UV-curable acrylate resin systems

In vitro data demonstrated that the permeation of a UV-curable urethane acrylate resin system through glove materials was greatest for latex and neoprene gloves and less for two nitrile gloves. Permeation in vitro for the resin system took longer than 480 min. Individual components of the resin permeated faster when tested separately than when in the formulated system. In vivo 48-h patch test data suggested that neither nitrile glove would be adequate for worker protection, but the in vivo test exaggerated the duration of contact between resin, glove, and skin. Both nitrile gloves provide adequate protection under use conditions, provided the gloves were not re-used within 8 h.
