Abstract

Alkyd and epoxy coatings, which had been soaked in aqueous solutions of 0.25M FeCl3, pH between 0.5 and 1.5, were studied in Mossbauer spectroscopy and electron microscopy. Small particles (10-50 nm) of $BETA-iron oxyhydroxide, iron hydroxides, and iron hydroxychloride were formed within the polymer matrix. The solutions in which the coatings were immersed were also studied. No solid particles were detected in the solution by Mossbauer spectroscopy of frozen solutions.
