Demonstration of Bonderite M-NT 7400 at Red River Army Depot
Abstract
The US Army Combat Capabilities Development Command (CCDC) Army Research Laboratory (ARL) was invited to conduct a demonstration to help transition from the recently cancelled highly 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 Red River Army Depot (RRAD). This pretreatment was previously demonstrated successfully at the Letterkenny and Anniston Army Depots. The demonstration platforms used at RRAD were an abrasive-blasted M2/M3 Bradley Fighting Vehicle hull and several related parts assemblies. RRAD staff painters participated in the application of the alternative material using a modified high-volume low-pressure spray apparatus supplied by CCDC Army Research Laboratory. The production painters were trained onsite by Henkel personnel in the mixing and application of the pretreatment. Many were impressed with the ease of application compared with the wash primer. RRAD will move to implement the usage of the chrome-free product.
