Development of Improved Electrodeposited Corrosion Inhibiting Primers

Abstract

This program was conducted to develop a cathodically applied electroprimer for adhesive bonding of aircraft structural components. This program is an extension of the effort performed under Contract F33615-76-C-5301 which evolved a modified epoxy electroprimer curing at 325F which provided high adhesive bonding strengths except that the -65F bonding strengths were somewhat lower than desired. The current program was established to develop a 250F curing corrosion resistant electroprimer with enhanced -65F adhesive bonding properties. Two electroprimers, SA-6411 and SA-6412, have been developed which meet the goals of the program. The electropriming system is unique and that it is a self-limiting electroplating process that easily coats, to a uniform thickness, all areas of parts including those that are difficult to coat by other conventional priming methods.
