THIN FILMS OF PAINT ON STEEL

The overall objectives of this study were to establish a rapid method for evaluating paint performance through thin films, and to find a substitute for an oil base primer containing red lead oxide. Due to factors involving homogeneity, continuity, and vehicle dilution effects, the thin film method for monitoring corrosion resistance, as conferred on steel by a primer, was not found to be satisfactory. Sixteen rust inhibitive primers were evaluated by various means and found to be inferior to an AASHTO M72-74 red lead in long oil primer. Of the primers tested which were compatible with existing red lead systems, a primer utilizing Nalzin SC-1 (zinc phospho-oxide complex) in a slow-drying oil alkyd appeared to be the most promising. /FHWA/
