Demonstration and Validation of Zinc-Rich Primer for Missile Weapon Systems

Due to increasing costs, regulatory pressure, and health risks to personnel performing these processes, the sustainability of the DoD's surface treatment capability is threatened. This effort seeks to demonstrate the increased corrosion inhibiting performance of zinc-rich primer on aluminum and steel components and a hexavalent chromium free replacement for DoD-P-15328 wash primer for large multi-metal assemblies. Wash primers are characteristically thin and applied directly to the substrate to provide protection from corrosion and promote adhesion. This program will provide laboratory and field demonstration/validation of zinc-rich primer for use on multi-metal missile ground support equipment. This will include corrosion and adhesion evaluations of the required coating stack ups and control, demonstration validation of successful candidate processes, and final reporting from AMCOM CPO.
