specmat request for polyimide thinner

[Mary Tang]

Hi all --

This is a mixture of two chemicals which I believe are already accepted 
for use in the lab.  NMP is OK.  And PGME, I am not sure we've 
explicitly OK'ed for use in the lab before, but it is of the same family 
of "acceptable" propylene glycol ethers which appears in many resists.  
I think these are fine, given the standard precautions for labeling, 
handling, and waste disposal.
