Electro-Deposited Primer Development and Low-Polluting Primer Evaluation
Abstract
The objectives of this Air Force program are to develop, evaluate, demonstrate, and qualify an electro-deposited (ED) corrosion resistant primer system for metal bonding suitable for use with 350 F curing adhesives and to evaluate other low-polluting primer systems (such as water-base spray and dip systems or inorganic primers) which would be suitable for use with 350 F curing adhesives. Several electro-deposited primer formulations were evaluated to determine the optimum primer. The best primer developed met all of the initial adhesive bonded corrosion performance criteria in the laboratory. Scale-up to 6- gallon, and eventually 200-gallon demonstration of the electro-deposited priming process was planned; however, the primer was not successfully demonstrated. Additional work on the primer formulation and/or process equipment design is necessary and could not be accomplished within the provisions of this contract. Water-base primers were tested; the most promising was further tested and readily exceeded program requirements. Keywords: Adhesive bonding; Electro-deposited primer; Water-base primer; Metal bonding; Corrosion resistance.
