You can make epoxy fall to bits just by boiling your thing for 10 min untill the whole thing gets to 100 real degrees.
For silicone use Dichloromethane (DCM), this makes the rubber crumbly.
Some people say that an overnight soak in transmission fluid kills silcone. Never tired it myself.

Make sure its old school acetone based,loads of the stuff is now "eco friendly" and wont be any good

Had some of the rock epoxy, so dropped the whole lot into a bottle of MEK, and left it there for 3 months, till the epoxy was soft enough to pick off. The little PCB in the middle did not survive, but at least I was able to see what it was, which was a simple JFET buffer module for some chart recorder, of which I only had the buffer. Resistors all I had to measure as they also lost the paint. The capacitors, metal film, were dissolved.
