[labnetwork] PDMS processing - separate lab?

[Howard Northfield]

PDMS (resin and hardener) preparation is absolutely forbiddent in our clean room.  Was once prepared in our clean room. Ruined a bunch of dishes and the sink was tacky for ages. Could not remove it with Acetone, IPA, TMAH, 1-methyl 2-pyrrolidinone  (1165,PG-R).

All PDMS preparation must be done externally. I suggest a dedicated, external PDMS preparation area

Lab Network,



I am curious how many fabs allow PDMS mixing in their main cleanrooms and how many require that work done in separate isolated spaces or noncleanroom labs. My experience has been that they can be in the same space if careful glove protocols are used to avoid spreading the unpolymerized precursors around the facility, but I am interested in other’s experiences. Thanks for the shared knowledge.
