Abstract
Chemical solvating, degreasing, stripping and cleaning agents. The agents are cleaning and solvating mixtures of mono brominated compounds with highly fluorinated compounds and/or other agents that improve and enhance the properties of the original mixture. The addition of these agents to the composition will modify the physical and/or cleaning characteristics of the monobrominated compound and/or monobrominated compound-fluorinated compound mixture to accomplish is desired cleaning or solvating task. These other agents are one or more of the following materials: alcohols, esters, ethers, cyclic ethers, ketones, alkanes, terpenes, dibasic esters, glycol ethers, pyrollidones, or low or non ozone depleting chlorinated and chlorinated/fluorinated 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, drycleaning, degreasing, particle removal, metal and textile cleaning.
