Process

U.S. Patent 5,514,221. May 7, 1996 M.S. Bolmer, assignor to Nf Atochem North Inc., Philadelphia

A method for cold cleaning of an object, which comprises the steps of contacting in an open environment with a nonazeotropic solvent blend consisting essentially of l-60% by weight of a hydrochlorofluorocarbon, hydrofluorocarbon, or perfluorocarbon halocarbon component having 2-4 carbons, a boiling point of 2545”C, and no flash point; l-30% of a nonflammable chlorinated solvent component with a boiling point of 80-130°C selected from perchloroethylene, trichloroethylene, or mixtures thereof; and l-40% of an oxygenated organic solvent component, which has a flash point over O’C, has a boiling point intermediate that of the other two components, and is selected from methanol, ethanol, isopropanol, isopropyl acetate, dim-

he solution may be simpler than you think.

At Greco Brothers we put our fifty years of experience ond technical expertise to work: trofting affordoble tleoning systems which ore masterfully designed for your specific opplicotion. Our Aqueous Cleaning Systemsexpertly utilize and reqtle water to remove every speck of foreign matter from the port being cleaned. And once the port is dean, one of our Hot Air Dryersor Fluid Displacement Drying Systemswill remove the water-leaving the port free of film or spots. For non-aqueous cleaning, we offer 0 complete line of AdvancedVapor Degreesing Systems[AVD] which provide the odvontages of stondord vapor degreosers, without threatening the environment. So toll Greta Brothers today, and let us show you how simple the solution to your tleoning problem con be.
