Adhesives and Epoxies Q&A

I am looking for a solvent for DC 3140 room-temperature vulcanizing (RTV) silicone. My problem is that a subcontracting manufacturer uses DC 3140 RTV silicone to cover and protect fragile magnet wiring in a miniature component. The RTV is approximately 10 mil thick. The wire insulation consists of a nylon undercoating and a polyurethane overcoat, each measuring only approximately 0.2 mil thick. To perform failure analysis on the wire, I need to remove the RTV while causing minimal damage to the wire insulation.Answered June 11th, 2010 by Expert:Common solvents for these systems are often toluene or xylene. Sonication baths help to loosen the material and remove it to expose underlying layers, but it still might take two to three days for thin coatings and longer for thick coatings. Scoring the surface helps give the solvent areas to work on and through to penetrate deeper into this thick coating. For an environmentally cleaner solution, Dynaloy Dynasolve CU-6, 217, and 220 from Dynaloy LLC (Indianopolis) have been effective at removing different coatings. Dynasolve 217 and 220 are listed as being able to dissolve cured silicone. In any case, I would suggest doing a test on a separate wire without silicone around it to see if it affects the wire jacketing and insulation material.
