To summarize: There are three primary materials that PCBs can be encapsulated with: polyurethane; epoxy; and silicone. Of these, silicone is usually the easiest to remove, as it is intentionally flexible and can develop tears that can allow a silicone encapsulation to be peeled off. If you can’t peel off the silicone, use either a silicone digestant such as PROSOCO Dicone NC9 or DOWSIL DS-2025, or xylene. Xylene should be used only as a last resort and only outdoors or in well ventilated conditions, as it is both highly flammable and a CNS depressant, and long-term exposure may lead to headaches, irritability, depression, insomnia, agitation, extreme tiredness, tremors, hearing loss, impaired concentration and short-term memory loss.
