Abstract:

The US Army Research Laboratory ARL was invited to conduct a demonstration to help transition from the recently cancelled high volatile organic compound containing DOD-P-15328 hexavalent chrome wash primer to a TT-C-490 Type IV approved chrome-free alternative pretreatment. A technology with a similar application process as the wash primer was selected for the production facility at the Anniston Army Depot ANAD. This pretreatment was previously demonstrated successfully at Letterkenny Army Depot. The demonstration platform used at ANAD was an abrasive-blasted M992 A2 Field Artillery Ammunition Support Vehicle FAASV V hull. Nine staff painters participated in in the application of the alternative material using the high-volume low-pressure spray equipment supplied by ARL. The production painters were trained onsite in the mixing and application of the pretreatment. Many were impressed with the ease of application compared with the wash primer. In addition to the demonstration on the FAASV hull, the ANAD production engineer is considering using it on the paint lines for small parts. The demonstrated product is approved for immersion and spray application in TT-C-490.
