ProTEK PSB and Primer, polymeric KOH and TMAH mask.

[Tracy Fung]

Attached are the MSDS for both the ProTEK PSB and Primer.  

Intended use at headway2 or laurel, as well as UV exposure using KarlSuss.
Also wbgeneral for use as a mask during KOH and TMAH etching. 

 

We have been unable to verify the claim that the ProTEK PSB is resistant to
strong alkaline etchant such as KOH and TMAH.  And they have been unwilling
to supply small quantities (grams) for this purposes.  The minimum $1200
purchase is for 250mL of Primer and 250mL of PSB.  I would like to ask if I
can CC an SNF representative in emails requesting sample gram sized
quantities for evaluation purposes.  Brewster sciences appears to be
interested in the use of their ProTEK PSB at the SNF and perhaps if had more
pressure would supply smaller/cheaper evaluation samples.

 

With a confirmation of KOH and TMAH resistance Silexos does plan to purchase
larger quantities.
