Abstract

This ATM presents the results of the S-13G thermal coating investigation conducted in support of the ALSEP Flight 1 central station adhesion paint failure. The report includes a summary of the events that occurred during the investigation, a comprehensive review of S-l3G coating application history at BxA, the results of BxA and IITRI coupon tests to determine the cause for the loss of adhesion and establish corrective action, and recommendations for changes to the manufacturing process procedure for subsequent ALSEP painted hardware.
