Summary Background Epoxy products are among the most common causes of occupational allergic contact dermatitis. Diglycidyl ether bisphenol A resin ( DGEBA‐R ) is important sensitizer in epoxy systems. Objectives To describe patients with dermatitis caused by products. Methods Patients reactions to chemicals were chosen from test files J anuary 1991 une 2014). Only allergy some component systems included. We analysed patch results, occupation, symptoms, and exposure data. Results found a total 209 cases chemicals. The largest groups painters (n = 41), floor layers 19), electrical industry workers tile setters 16), aircraft 15). 82% reacted . Diagnosis ‐negative required testing m ‐xylylenediamine, N , ′‐tetraglycidyl‐4,4′‐methylenedianiline, 1,4‐butanediol diglycidyl ether, 2,4,6‐tris‐(dimethylaminomethyl)phenol, F resin, ′‐diglycidyl‐4‐glycidyloxyaniline, isophoronediamine, 4,4′‐diaminodiphenylmethane, diethylenetriamine, cresyl glycidyl ether. hands/upper extremities commonly affected (69%), but facial symptoms also frequent (60%). Conclusions Allergic cannot always be diagnosed use commercial substances. Workplace need tested.
