Patent number: 5322870Abstract: An additive package can be used in a single-coat, in situ self-phosphatizing paint to provide a phosphate layer that inhibits corrosion of a surface on which the paint is applied. The additive package includes an amine and a phosphatizing reagent that can be an alkyl-, phenyl- or aryl- ester phosphoric acid or an alkyl-, phenyl- or aryl-phosphonic acid. The reagent and the amine are present in a ratio effective to produce reagent-amine complexes. A paint can include the additive package in addition to a polymer coat forming resin and a cross-linking agent.Type: GrantFiled: December 29, 1992Date of Patent: June 21, 1994Assignee: Board of Regents, Northern Illinois UniversityInventor: Chhiu-Tsu Lin
