Contact dermatitis, 11(2), 80-82 (1984-08-01)
An outbreak of dermatitis occurred in an aircraft factory using epoxy resin composite material. Of 25 operatives, 14 gave positive patch test reactions to the composite material and/or diglycidylether of bisphenol A (DGEBA), tetraglycidyl-4,4'-methylene dianiline (TGMDA), and o-diglycidyl phthalate. This...

Dermatology (Basel, Switzerland), 201(1), 29-33 (2000-09-06)
Very little is known about allergic contact dermatitis (ACD) from preimpregnated epoxy products (prepregs). To describe a patient with occupational ACD from prepregs, and report new quantitative data on the content of prepregs. A laminator developed work-related vesicular hand dermatitis....

Polymers, 12(5) (2020-05-21)
Epoxy-anhydride vitrimers are covalent adaptable networks, which undergo associative bond exchange reactions at elevated temperature. Their service temperature is influenced by the glass transition temperature (Tg) as well as the topology freezing transition temperature (Tv), at which the covalent bond...
F Ayala et al.
Contact dermatitis, 22(5), 262-266 (1990-05-01)
Thin-layer chromatography, column chromatography, mass spectrometry and nuclear magnetic resonance were used to investigate the chemical constituents and haptens responsible in 2 different circumstances where allergic contact dermatitis from composite materials was suspected. In an aircraft factory where epoxy resins...
