Abstract

A silicone dissolving composition includes an organo-acid compound such as sulfonic acid or phosphinic acid, a solvent miscible with the organo-acid and able to swell a silicone, a thickener and a small amount of mineral acid. Silicone films dissolve to a liquefied mass capable of being wiped from a substrate in a matter of minutes. The removal of automotive, electrical, and construction sealants and gaskets is simplified with the use of such a silicone dissolving composition.
