Stephen, Go to the IPC homepage and use the archive search function at: http://jefry.ipc.org/archives/technet.html It will let you enter a keyword and then will create a thread on that topic from the archive. There aren't a lot of messages specifically on Pyralux over the last few years (13). You might want to include the more general "acrylic" in the search. Do you have a specific question? I may have some information, or you could go to DuPont directly.
