[Contact allergy to epoxy resin hardeners]

447 patients suffering from eczema, occupationally exposed to epoxy resins, have been tested with Epidian 5 and five triethylenetetramine concentrations. By comparing the obtained results with literature data it has been found that in Poland those health damages are characterized by a considerable percentage of those sensitized to triethylenetetramine. The calculation of eczema incubation period and testing the allergen by several allergen concentrations demonstrated that the sensitivity to triethylenetetramine is sometimes very enhanced.
