ABSTRACT:
Chemical solvating, degreasing, stripping and cleaning agents. The agents are cleaning and solvating mixtures of dichloroethylene and alkoxy-substituted perfluoro compounds that contain six carbon atoms, with optionally highly fluorinated materials to retard flammability and/or other enhancement agents that improve and enhance the properties of the composition to accomplish its desired cleaning or solvating task. These other agents are one or more of the following materials: alcohols, esters, ethers, cyclic ethers, ketones, alkanes, aromatics, amines, siloxanes terpenes, dibasic esters, glycol ethers, pyrollidones, or low- or non-ozone depleting halogenated hydrocarbons. These mixtures are useful in a variety of solvating, vapor degreasing, photoresist stripping, adhesive removal, aerosol, cold cleaning, and solvent cleaning applications including defluxing, dry-cleaning, degreasing, particle removal, metal and textile cleaning.
