Patent number: 5849106Abstract: An industrial cleaning process in which a contaminant comprising soldering flux and/or adhesive tape residue is removed from a substrate contaminated therewith, for example, a printed circuit board contaminated with rosin flux, comprising: (A) contacting the substrate with a terpene-based cleaning composition which is substantially free of water-soluble organic material, for example, a surfactant, for a period of time sufficient to solubilize the contaminant; (B) removing the composition and solubilized contaminant from the substrate by contact with water having a temperature of about 70.degree. F. to about 140.degree. F.Type: GrantFiled: May 26, 1993Date of Patent: December 15, 1998Assignee: Petroferm Inc.Inventors: Paul L. Bolden, Michael E. Hayes, John E. Braddy

Patent number: 5705472Abstract: An aqueous cleaning composition having a pH of about 6 to about 8 and comprising a solution of the following ingredients: water, an organic solvent and an imidazoline-based cationic surfactant, each present in an amount effective to dissolve adherent soils from a substrate; and a nonionic surfactant in an amount sufficient to maintain said cationic surfactant in solution; and also a weak organic acid in an amount sufficient to impart to the composition said pH; wherein said composition is substantially free of any material which has an ozone-depletion factor of greater than about 0.15 and wherein said composition is substantially free of any material which would tend to form a solid with any of the ingredients comprising the composition, and its use to clean metallic and non-metallic surfaces.Type: GrantFiled: July 18, 1995Date of Patent: January 6, 1998Assignee: Petroferm Inc.Inventors: Michael E. Hayes, Elizabeth A. Bivins, Jacquelyn B. Coleman

Patent number: 5340407Abstract: Disclosed is an industrial cleaning process in which a contaminant comprising soldering flux and/or adhesive tape residue is removed from a substrate contaminated therewith. The process comprises the steps of contacting the substrate with a terpene-based cleaning composition which is substantially free of water-soluble organic material; removing the composition and solubilized contaminant from the substrate by contact with water having a temperature of about 70.degree. F. to about 140.degree. F. for a period of time of no longer than about 10 minutes to provide a substrate having a contamination rating of no greater than about 14 micrograms NaCl equivalent/square inch (MIL-P-28809A), and to thereby form a mixture comprising the composition, contaminant and water. The process also comprises separating the water from said mixture, the separated water being substantially free of water-soluble organic material and having a chemical oxygen demand of no greater than about 1,000 ppm.Type: GrantFiled: June 9, 1992Date of Patent: August 23, 1994Assignee: Petroferm Inc.Inventors: Paul L. Bolden, Michael E. Hayes
