The U.S. Army Research Laboratory has evaluated new water-reducible wash primers that do not contain hexavalent chromates and significantly minimize volatile organic compound VOC- and hazardous air pollutant-potential emissions during coating operations. The new wash primers are water-borne acrylic latex emulsions with corrosion-inhibiting pigments. The three water-reducible acrylic latex emulsion formulations are designed for use under MIL-P-53030, a water-reducible lead and chromate-free epoxy primer. Tests are required on military equipment to validate the completed laboratory and controlled testing. The ultimate objective of the process is to demonstrate that the low VOC wash primers can provide a drop-in solution to the environmental issues associated with the solvent-based primer currently in use and provide equal or better performance involving no significant changes to the application and stripping procedures currently being used. The field demonstration of this coating was tested on a Patriot truck unit, with serial no. 630106, at the Letterkenny Army Depot facility, Chambersburg, PA. The unit is an engagement control system ECS. The ECS is the only manned station in the battery during the air battle and is the operations control center of the Patriot battery. The ECS contains the weapons control computer, manmachine interface, and various data and communication terminals. Its prime mover is a 5-ton tactical cargo truck.
