Publication number: 20120160685Abstract: A process for forming a multilayer composite coating on a substrate is provided. The process includes forming an electrodeposition coating layer on the substrate by electrodeposition of a curable electrodepositable coating composition over at least a portion of the substrate. Optionally, the coated substrate is heated to a temperature and for a time sufficient to cure the electrodeposition coating layer. A basecoating layer is formed on the electrodeposition coating layer by depositing an aqueous curable basecoating composition directly onto at least a portion of the electrodeposition coating layer. Optionally, the basecoating layer is dehydrated. A top coating layer is formed on the basecoating layer by depositing a curable top coating composition which is substantially pigment-free directly onto at least a portion of the basecoating layer. The top coating layer, the basecoating layer, and, optionally, the electrodeposition coating layer are cured simultaneously.Type: ApplicationFiled: January 31, 2012Publication date: June 28, 2012Applicant: PPG INDUSTRIES OHIO, INC.Inventors: Sean Purdy, Dennis A. Simpson, Richard J. Foukes, David M. Aiken, James P. Rowley, Leigh Ann Humbert

Publication number: 20110045725Abstract: Film-forming coating compositions are disclosed. The composition comprises a) an epoxy-containing polymer system; and b) a polyacid curing agent comprising two acid functional groups per molecule; wherein the epoxy-containing polymer system comprises: (i) an epoxy resin comprising at least two epoxy functional groups per molecule and which is different from (ii); and (ii) an epoxy functional silsesquioxane. Also disclosed are processes for applying the film-forming composition to a basecoat, and substrates coated in part by a coating deposited from the film-forming compositions.Type: ApplicationFiled: August 24, 2009Publication date: February 24, 2011Applicant: PPG Industries Ohio, Inc.Inventors: Shan Cheng, Thomas R.

Patent number: 3991599Abstract: Three cylindrical rollers are rotatably mounted equidistant from the center of a hollow tool head on radii spaced 120.degree. apart. Each roller has a thin flange; the three flanges lie in a single plane to form an internal circumferential rib in a rotating tubular workpiece. The tool head has two complementary parts with two rollers in one part of the head and one roller in the other part; the two parts are joined by a hinge. A second hinge, located so the rollers are between the two hinges, connects one of the parts to a tool bar mounted in a lathe tool holder. The axes of rotation of both hinges and all three rollers are parallel. A hole exposing equal portions of the three roller flanges is located in the center of the tool head. The two hinges permit the tool head to be opened and rotated slightly downward, taking the roller flanges out of the path of the workpiece which is supported on both ends and rotated by the lathe.Type: GrantFiled: December 2, 1975Date of Patent: November 16, 1976Assignee: The United States of America as represented by the United States Energy Research and Development AdministrationInventors: James P.
