Technovit 9000 is a methyl methacrylate kit.  To remove MMA from thin 
microtomed sections, soak  sections in 60C xylene X 3 changes, proceed with 
rehydration.  You probably will have to use Neil Hands rather stringent 
pressure cooker retrievals for IHC.   He has a publication in J of 
Histotechnology a few years back on how he succeeded with retrieval using 
MMA.  You can access the journal for first page/abstract of publication via 
www.NSH.org   click on J of Histotechnology.
