  • Carbamated polyols, and compositions and methods using the same
    Patent number: 7078077
    Abstract: The present invention is directed to coatings that provide improved retort and tropical decay resistance for use on metal food containers. The coatings generally comprise a carbamated polyol formed by the reaction between a polyol, an alkylene oxide and an alkyl carbamate. A crosslinker reactive with the carbamate functionality is used to react with the carbamate moiety. Methods for improving retort resistance and resistance to tropical decay are also disclosed, as are substrates coated with the present compositions.
    Type: Grant
    Filed: August 15, 2003
    Date of Patent: July 18, 2006
    Assignee: PPG Industries Ohio, Inc.

  • Water based coating composition with improved process resistance
    Patent number: 5266628
    Abstract: A coating composition which may be water based and which is adapted for metallic substrates is disclosed, having: (1) binder resin comprising acrylic polymer having carboxy functionality, and (2) a curing agent comprising hydroxyalkylamide, wherein the ratio of hydroxy groups in the hydroxyalkylamide to carboxy groups in the binder resin is less than 0.5:1, preferably less than 0.4 to 1, and most preferably less than 0.35 to 1. The composition has been found to yield films exhibiting good resistance to water at high temperatures, thereby rendering them particularly suitable for use on metal food and beverage containers that are subjected to sterilization or pasteurization processes.
