MIL-PRF-32550 (W/ AMENDMENT-1), PERFORMANCE SPECIFICATION: METAL-RICH PRIMER (18-FEB-2020)
MIL-PRF-32550 (W/ AMENDMENT-1), PERFORMANCE SPECIFICATION: METAL-RICH PRIMER (18-FEB-2020)., This specification governs the performance of metal-rich primers used in corrosion protection of abrasive blasted steel substrates. These primers use metallic and/or metal-rich particles that make up part of the pigment content to provide sacrificial cathodic protection to abrasive blasted steel substrates. The primers are lead and chromate free and meet air pollution requirements for solvent emissions. The metal-rich primers are compatible with the epoxy primers and topcoats that are used in the Chemical Agent Resistant Coating (CARC) System.
