Abstract:
A solvent composition has an oxygenated solvent and a siloxane solvent. In one embodiment, the oxygenated solvent is propylene glycol methyl ether and the siloxane solvent is hexamethyldisiloxane or octamethyltrisiloxane. In another embodiment, the solvent composition is an azeotrope of propylene glycol n-butyl ether and decamethyltetrasiloxane. The siloxane solvent can be used in any situation where one desires to remove a silicone deposit, e.g., conformal coatings, adhesives, sealants, greases, heat transfer fluids, paints, oils, etc.
