Project Correspondence ArchiveTopic: Molybdate Treatment
Greetings Paul, I trust you had a safe and happy Holiday. We enjoyed the season and enjoyed thinking about the prospects for the new year. I thought you would want to read this message that came from Bob Hill where he bumped into a new formula for a non chromated converson coating. Best regards Denny From: "Hill-1, Robert" <HillRP@kscgws00.ksc.nasa.gov>, on 12/17/98 8:35 AM: ... Thanks for forwarding the information. We are working with Paul Chalmer on starting and accomplishing this as a JG-PP/NCMS project. Paul is attempting to identify those with the common chrome conversion problem within the industry. As timing is everything, I received just yesterday a briefing from a company completing a Phase 2 SBIR for NASA. The company is Lynntech, Inc from College Station, Texas. They have been working for two years on an alternative for chrome conversion coating for aluminum alloys for NASA. It looks like they have found a good solution. They have a molybdate treatment that has exceeded 500 hours salt fog test on 2024 high copper aluminum coupons. Not to bad. Mr Oliver Murphy, Lynntech President, is very interested in completing the PHASE 2 SBIR period by accomplishing the paint adhesion and electrical resistance test. I mentioned to Mr Murphy the opportunity of not only testing coupons with their conversion coat, but alos testing coupons from a system perspective with a topcoat on them. He was very interested in doing that if I could coordinate a few participants to apply those topcoats. ... Regards, Bob Hill
