Reduced Volatile Organic Compound (VOC) Ammunition Coatings

摘要

Production requirements and film thickness limitations typically require thatammunition coating systems consist of a single film. This single film must provide the corrosion resistance of a primer plus such properties as color, gloss, and solvent resistance that are required of a topcoat, a compromise at best. Federal and local regulations resulting from the Clean Air Act and its amendments restrict the amount of VOC emitted during the application of protective coatings, and regulations on worker safety restrict exposure to hazardous materials such as chromates. These materials also generate hazardous wastes and the associated high disposal costs. This report summarizes progress in developing ammunition coatings that perform as well as or better than current systems, but at reduced VOC levels with chromate-free pigmentation.
