Patent number: 5854190Abstract: An apparatus, method and purge concentrate are capable of purging water-based and non-water-based paints and other coatings from automated and manual equipment using non-VOC containing aqueous purge solutions. Purge solutions of the invention contain water, detergent builder and wetting agents. The solution is maintained at a selected concentration and at a selected elevated temperature range by continuously recirculating the solution through the automated coating equipment. For manual equipment the solution is set at the correct concentration and maintained at the correct temperature range. For an automated system, spent purge solution can be reconditioned and recirculated to avoid waste.Type: GrantFiled: October 15, 1997Date of Patent: December 29, 1998Assignee: DALCO Industries, Ltd.Inventors: Richard E. Knipe, Jr., Savarimuthu M. Jacob, Thomas Mancini

Patent number: 5814588Abstract: Aqueous alkali cleaning compositions containing an alkali metal salt, an N-alkyl pyrrolidone derivative, and specific ethylene oxide/propylene oxide block copolymers having molecular weights of from about 1500 to about 2500. Such compositions can be employed as an aqueous concentrate or solution to clean a substrate such as a circuit board, wiring board or metal surface. Specific ethylene oxide/propylene oxide block copolymers protect plastic parts from corrosion by N-alkyl pyrrolidone derivatives without compromising N-alkyl pyrrolidone derivative cleaning ability.Type: GrantFiled: March 19, 1996Date of Patent: September 29, 1998Assignee: Church & Dwight Co., Inc.Inventors: Francis R. Cala, Richard A. Reynolds
