Publication number: 20240279506Abstract: The present invention relates to a powder coating composition for preparing a dielectric coating. The powder coating composition includes: (a) an epoxy functional polymer; (b) a poly-carboxylic acid functional polyester polymer reactive with the epoxy functional polymer and which has an acid value of less than 100 mg KOH/g; and (c) a poly-carboxylic acid functional (meth)acrylate polymer reactive with the epoxy functional polymer. Further, if a colorant is present, the powder coating composition comprises 35 weight % or less of the colorant, based on the total solids weight of the coating composition.Type: ApplicationFiled: April 14, 2024Publication date: August 22, 2024Applicant: PPG Industries Ohio, Inc.Inventors: Anthony Michael Chasser, Paul F. Cheetham, Holli Allison Gonder-Jones, Stacey Lynn Orzech, Brian Edward Woodworth, Brent Allen Schwartz, Kevin Lee Ford

Patent number: 11753561Abstract: A patterning paste is disclosed for patterning metal nanowires, the patterning paste including a complexing agent containing guanidine thiocyanate. A method of selectively patterning a substrate having metal nanowires includes: providing a substrate having a surface bearing metal nanowires; and selectively applying the patterning paste to the substrate such that the metal nanowires are selectively cut into a pattern. A consumer electronic product includes: a substrate having a surface bearing metal nanowires. The metal nanowires of the substrate are selectively patterned by applying the patterning paste to the substrate such that the metal nanowires are selectively cut into the pattern.Type: GrantFiled: November 20, 2018Date of Patent: September 12, 2023Assignee: PPG Industries Ohio, Inc.Inventors: Paul F.
