Kenny,
A terpene based material dissolving Teflon? Either there is something else
in that material that you should be scared of or someone pulled a fast one
on you with that tape! Personally I don't know of anything that will
dissolve a pure, fully polymerized PTFE, short of maybe boiling aqua regia
or molten sodium hydroxide. I will see if I can get a copy of the MSDS for
Citrex from our local EHS guy.
regards,
Bev Christian
