Why Use a Silicone Adhesive? | MasterBond
Silicone adhesives boast excellent electrical properties and can be formulated to be insulative with a high dielectric strength, or conversely electrically conductive. Many one part silicone adhesives release a corrosive entity, such as acetic acid, but there are special formulations that are totally non-corrosive and can be used with electronics.
