What's in a name?
Some product names are straightforward, like PMMA 950K A4.
PMMA: polymethylmethacrylate
950K: molecular weight
A4: solvent and solids wt%, in this case anisole 4%
NBI cleanroom uses this convention. E.g. A4, EL6 (PMMA 950K ethyl lactate 6%), CSAR9 (CSAR 9%).
Some product names are vendor specific, like AR-P 672.045.
AR: vendor AllResist
P: positive resist
672: product series, in this case PMMA 950K in anisole
045: 4.5% solids in wt%
Purchasing
micro resist
MicroChem was bought by Kayaku. micro resist is the European distributor.
Slow lead time (3-6 weeks), short shelf life (11 months), large minimum (500 ml), expensive.
Always ask for expiration date of the batch you're ordering, might be as short as 3 months.
Only source for copolymer EL-series (MMA (8.5) MAA in ethyl lactate).
