Potential Alternatives Report

A PAR, dated February 1, 2001, identifies the baseline process for applying coatings to medium caliber ammunition projectile bodies; discusses potential alternative technologies; identifies initial environmental, safety, and health screening data; and documents the down-selection process. Alternatives considered in the PAR include high-solids coatings, powder coatings, waterborne coatings, and ultraviolet-curable liquid coatings. In selecting alternatives to be tested, the project participants considered VOC content, hazardous constituents, curing temperatures, applied coating thickness, and other factors affecting use of the coating. Three coatings were selected for testing in accordance with the JTP:

• Two waterborne coatings:
  • KEM AQUA^® enamel from Sherwin-Williams
  • TioTech^® 40 from Tioga Coatings and
• One high-solids UV-curable liquid coating:
  • KS-5 from Ecology Coatings.
