Residue vs. 3M 1357 Adhesive

Tests[1, 2] conducted at the National High Magnetic Field Laboratory (NHMFL), Tallahassee, FL and West Coast Analystical Services (WCAS), Santa Fe Springs, CA.

The following data are from results of elemental analysis. The first column lists the inorganic elements by name. The second column depicts the red residue tested by WCAS for James Sanders and the third, 3M 1357 Sotch Grip Adhesive tested at NHMFL. The fourth column represents an adhesive sample, also tested by NHMFL, taken from a sistership to TWA 800 and soaked for three weeks in ocean water. This adhesive sample was taken from a seat, retrofitted at the same time as TWA 800's seats, according to a TWA mechanic and flight attendant. All numbers represent the percentage of a given element by mass.
