Metal cans are often protected from corrosion by vinylic organosol coatings, made from PVC and epoxyphenolic (EP) resins. Using electron spin resonance, BADGE, a monomer of EP, was shown to plasticize PVC. Optimization of extraction allowed extraction of 4 mg of BADGE/dm2, so vinylic organosols appear to be worst-case coatings. Comparison of behavior between BADGE and a paramagnetic probe revealed that these compounds ...
