Powder Coatings as an Environmentally Acceptable Alternate to the System of MIL-P-53022 and MIL-PRF-22750
Abstract
In late 2000, Albany Marine Corps Logistics Base (MCLB) personnel contacted the Coatings Technology Team, Weapons and Materials Research Directorate, US Army Research Laboratory (ARL) about a test program designed to approve the use of epoxy powder coatings as replacements for the standard chemical agent resistant coating (CARC) system used on tactical equipment, because ARL is the CARC Commodity Manager and the CARC approving authority for the Department of Defense. The powder coatings were to be used on a variety of equipment to replace the military specification MIL-P-53022 (1) epoxy primer and MIL-PRF-22750 (2) epoxy topcoat as applied to bare and pretreated aluminum and zinc phosphate pretreated steel. Normally, substitutions are for cases where those specifications do not meet volatile organic compounds (VOC) regulations in force or where new technology will provide more general benefits in the future or a more environmentally acceptable process for the user. Although these specification coatings are available in low-VOC formulations, the environmental benefits (zero VOC) and performance enhancements of powder coatings are well documented. The proposed test program ARL's approval process fell under the auspices of ARL's Experimental Products Program (EPP), which is set up to evaluate performance alternatives to military specification finishing systems. After discussions to set the number and type of panels required, panels were submitted for three powder coatings on three different substrates.
