Hi Dave --

Protek B plus associated primer and remover chemicals are approved for 
use in the lab at limited locations.  (Spin coating at headway only, 
etching at wbgeneral, wbgen2, etc.)  We do not currently supply Protek B 
-- primarily because there are few users and it has a limited shelf life 
(6 months) -- not enough demand to justify the cost.  You are welcome to 
order material and use it in the lab.  Brewer Science has been generous 
and has sent samples to the previous two requesters of this material 
(Harold Ackler and Debbie Gunning), so I would suggest you contact 
Brewer directly.  They will ask a lot of questions about your specific 
application and require that you supply data on the results in exchange 
for a sample.  Yves -- you've spoken with them before, correct?  So you 
have their contact info?  Let me know if you don't -- I think I have it 

By the way, please still provide an outline of your process flow to 
SpecMat.  This will be helpful to us to try to establish some sort of 
baseline process flow to facilitate future requests.
