MSXA packaging

Marshall Experimental Sprayable Ablator (MXSA) ingredients were compounded into a two part system which requires a minimum of handling by the user. Preweighed two part kits were developed which require that the user supply only the solvent. The kits consist of all of the powdery materials in Part A, and the epoxy resin (AA397) in Part B. Recent aging data on the kits indicates that they are useable for at least 6 months. The acronym MXSA has recently been replaced with MSA (Marshall sprayable ablator).
