  • Electrodepositable coating compositions and electrically conductive coatings resulting therefrom
    Patent number: 11827809
    Abstract: The present invention is directed towards an electrodepositable coating composition comprising a film-forming binder and electrically conductive particles, wherein the electrically conductive particles are present in an amount of at least 25% by weight, based on the total solids weight of the electrodepositable coating composition. The present invention is also directed towards methods of coating a substrate, coatings, and coated substrates.
    Type: Grant
    Filed: December 20, 2018
    Date of Patent: November 28, 2023
    Assignee: PPG Industries Ohio, Inc.
