Glenn: Amines and anhydrides are two general families of chemistry 
used as curing agents for epoxy resin systems. They help give the cured resin 
its particular properties and performance.	 			
	Dyanalloy Inc. makes a wide range of decapsulation and stripping 
formulations. You may want to try their DECAP or DYNASOLVE 185. These will 
breakdown both anhydride and amine systems.
