The invention discloses a novel solution and process comprising a modified solvent for providing enhanced blade edge attributes.

The invention relates to a method for removing a substrate that is coated with an organic coated coating by means of ionogenic gel formation. In said method, a wet or dry organic coating that has not yet formed a film on the substrate is treated with an aqueous solution of a metal salt from main group I in the periodic table of the elements, a complexing agent and/or a basic compound having a pH value >10.

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.
