Abstract
A wet sanding adjuvant is comprised of a composition comprising: (1) an alkali metal or ammonium salt of an alkoxylated alkyl sulfate; (2) an alkali metal or ammonium salt of an alphaolefin sulfonate; (3) a cellulose derivative selected from the group consisting of hydroxyalkyl cellulose, a carboxyalkyl cellulose and combinations thereof. The adjuvant is used in a method of removing a coating from a surface comprising the steps of: (1) contacting a coated surface with a composition according to the invention to form a wet surface on the coating; (2) abrading the wet surface with an abrasive; (3) removing the composition from the surface.
