Patent number: 6689734Abstract: 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.Type: GrantFiled: July 10, 2002Date of Patent: February 10, 2004Assignee: Kyzen CorporationInventors: Kyle J. Doyel, Michael L. Bixenman, Scotty S. Sengsavang, Arthur J. Thompson, Valerie G. Porter, Patricia D. Overstreet, Kristie L. Gholson

Publication number: 20030220218Abstract: A non-flammable ternary liquid cleaner is formulated from first, second and third solvents. The first solvent is a hydrofluorocarbon, the second solvent is a dichloroethylene and the third solvent is a hydrochlorofluorocarbon. The hydrochlorofluorocarbon imparts low flammability to the cleaner. The hydrofluorocarbon is present in a concentration of about 10 percent to about 80 percent by weight of the cleaner, the dichloroethylene is present in a concentration of about 10 percent to about 60 percent by weight of the cleaner and the hydrochlorofluorocarbon is present in a concentration of at about 10 percent to about 40 percent by weight of the cleaner. The third solvent is non-flammable and thus renders the ternary cleaner non-flammable.Type: ApplicationFiled: May 23, 2002Publication date: November 27, 2003Inventor: James M. Fitzgerald
