DEGRADATION OF ORGANIC COATINGS BY IRRADIATION WITH LIGHT. III. VOLATILE PRODUCTS FROM SIMULATED SOLAR IRRADIATION IN AIR.
Abstract
Various clear vehicle films were irradiated in air with a xenon arc and the volatile products were identified by infrared spectroscopy. The films included alkyd, oil, vinyl-alkyd, vinyl, vinyl acetate, epoxy-amine, and epoxy-polyamide films. The volatile products obtained were qualitatively similar to those obtained by mercury arc irradiation of the same films, but the relative amounts of the various products were changed in many cases. The products from the mercury arc irradiation contained acetylene but those from the xenon arc irradiation did not contain acetylene. These differences in the products show that the more rapid deterioration in the ultraviolet light from the mercury arc differs from the deterioration obtained in the simulated sunlight from the xenon arc.
