GSDO Program Hexavalent Chrome Alternatives: Final Pretreatments Test Report

[摘要] Hexavalent chrome free pretreatments should be considered for use on Ground Support Equipment (OSE) and Electrical GroundSupport Equipment (EOSE). Both of the hexavalent chrome free pretreatments (Metalast TCP HF and SurTec 650C) evaluated bythis project met, and in some instances exceeded, the requirements ofMIL-DTL-5541 "Chemical Conversion Coatings onAluminum and Aluminum Alloys". For DC resistance measurements, both Metalast TCP HF and SurTec (!50C met initialrequirements following assembly and in many cases continued to maintain passing readings for the duration of testing.
