I don't. I had heard it was a wax but have no real knowledge here. Also the aircraft strippers have other active compounds too like acetone and MEK. All I know is the former Klean Strip Aircraft stripper would clean a black Lionel modern tender clean in about 3 minutes and a gray locomotive is about a minute. Lacquer thinner won't touch Lionel or MTH black, at least in under and hour. Maybe a few days. No idea how well Klean Strip's green replacement works yet.
Maybe some of the real chemists will chime in here. I only work with them.
