Exploratory Development of Corrosion Inhibiting Primers
Abstract
The objective of this program was to develop a corrosion inhibiting primer suitable for adhesive bonding which can also serve as corrosion protection for detail aluminum parts. The developed primer must be adaptable to an automated application method. The program utilized the electropriming application method and investigated the polyester, acrylic, and epoxy electropriming resins. The anodic and the cathodic electropriming processes were evaluated. The cathodic application was shown to be the preferred method when compared to the interfacial oxide effects produced by the anodic applications. Results of these studies produced a cathodically applied modified epoxy electroprimer, C-5301. Assessment tests of the C-5301 primer show acceptable corrosion protection capability and compatibility with current state-of-the art paint primers and topcoats. Adhesive bonding test results have shown the C-5301 primer superior in some applications and the control BR-127 primer superior in others. The electrodeposited C-5301 primer was shown to be far superior in reproducibility and uniformity. The developed C-5301 electroprimer is readily adaptable to automated processing methods and can provide uniform, reproducible films which are cost effective.
