Material(s) Targeted for Reduction/Elimination: Hexvalent Chromium
Phase(s) in Methodology: I, Identification and II, Technical
Milestones and Prior Decisions:
- Preliminary JG-PP
CBA
was performed at five facilities:
- Kennedy Space Center
- Marine Corps Logistics Base - Albany
- Naval Aviation Depot
- Oklahoma City Air Logistics Center
- Red River Army Depot.
- Technical representatives
identified preliminary lists of proposed alternatives as well as proposed
platforms for demonstration:
- AC-131 (formerly Boegel)
- Alodine 5200/5700
- Bi-K Aklimate
- Brent Chemcoat Oxsilan 0500
- Chemidize 727D
- Sanchem Safeguard 7000
- TCP
- X-it Prekote.
- Technical representatives agreed that, as general validation criteria, potential alternatives must perform as well as or better than chromate conversion coatings by themselves (bare/unpainted) or with representative coating systems.
- Leverage previous work including:
- JG-PP, Chrome-Free Conversion Coating Project (HMSC)
- Army, Non-Chrome Coating Process and Organosilane Pretreatment Process
- NAVAIR, Alternatives to Chrome Conversion Coatings
- Air Force, nonchromated conversion test and evaluation.
- Specifications and standards
for verifying technology include:
- Conversion coatings
- AMS-2474B
- AMS-2473E
- MIL-C-5541E
- MIL-DTL-81706A
- Paints
- MIL-C-22750
- MIL-C-53039A
- MIL-DTL-64159
- MIL-P-53022B
- MIL-P-53030A
- MIL-P-85582B
- MIL-PRF-23377G
- MIL-PRF-85285C
- Tests
- ASTM B 117-97
- ASTM D 2803-93
- ASTM D 3359
- ASTM D 714
- ASTM G 85-94
- Conversion coatings
Date of Last Meeting:
June 5, 2001
Next Scheduled Meeting: To be determined
Meeting and Teleconference Summaries:
On June 5, 2001, representatives from the Army, Navy, Air Force, NASA, and OEM's met with representatives from the JG-PP Working Group. The purpose of the meeting was to review and finalize the JTP and initiate the approval process. All objectives were met.
On August 15-16, 2000, representatives from the Army, Navy, Air Force, NASA and OEM's met with representatives from the JG-PP Working Group. The purpose of the meeting was to discuss Phase I testing, acquiring signatures for the JTP and review funding issues for the ESTCP/JG-PP Nonchromate Aluminum Pretreatments Project. All objectives were met.
On January 25-26, 2000, representatives from the Army, Navy, Air Force, NASA and OEM's met with representatives from the JASPPA. The purpose of the meeting was to kick-off the ESTCP/JG-PP Nonchromate Aluminum Pretreatments Project, and to begin identifying potential alternative technologies and performance requirements for qualifying alternatives.
