Abstract

A quantitative determination of epoxy powder paint and its thermal degradation products in air was carried out by infrared (IR) spectrometry. Using chloroform-d as a solvent allowed analysis at 1510 cm–1, where the aromatic absorption is about ten times stronger than at 1610 cm–1. Filter sampling was applied both to epoxy powder and to the high relative molecular mass thermal degradation products of a powder paint. Collection on filters and IR analysis proved to be simple, quick and accurate.
