JIMENEZ BAJO, L. et al. Sensibilización a bisfenol A y bisfenol F en trabajadores expuestos a resinas epoxi. Med. segur. trab. [online]. 2008, vol.54, n.211, pp.39-45. ISSN 1989-7790.

The applications of epoxy resins based on bisphenol A and F are extensive. Epoxy resins based on bisphenol F are new and more resistant than epoxy resins based on bisphenol A. Both of them cause allergic contact dermatitis. In the last 5 years, we have studied 39 cases of sensitization to epoxy resin. The results of our study were these: the global prevalence of epoxy resin sensitization was 2%, 27 men and 8 women. The mean age was 42.77 years and the sensitization period was 23.8 months. The most frequent localization of the lesions were hands (84% of the patients). Since bisphenol F was included in epoxy resin battery for patch testing, a 100% of positives responses in patients sensitized to epoxy resin have been found. Sensitization to epoxy resins was a cause of change in workplace in 46% of cases in our series. There has been an increase in sensitization of bisphenol F that could be explained by a concomitant sensitization with bisphenol A, cross-reactivity between bisphenol Aand F or because an incorrect chemical compound information of the resin.
