  • Layer of reaction product of epoxy and phosphorus materials and curing agent on substrate
    Patent number: 7476444
    Abstract: A corrosion resistant, alkali resistant coating composition is disclosed. The composition comprises a binder comprising a reaction product of an epoxy-containing material and a phosphorus-containing material together with a curing agent. Aminoplasts, especially melamine-based aminoplasts, are particularly suitable curing agents. A source of silicon can optionally be included. The compositions also provide excellent adhesion and can be used with or without a weldable primer. The compositions are applied to and cured on a metal substrate.
    Type: Grant
    Filed: September 15, 2006
    Date of Patent: January 13, 2009
    Assignee: PPG Industries Ohio, Inc.
    Inventors: Michael J. Pawlik, Dennis W. Jones, Ralph C. Gray, Richard M Nugent, Jr., Yves Le Disert, Laurent Deronne
