  • Primer coating of steel
    Patent number: 8128996
    Abstract: A process for primer coating a steel substrate with a primer coating comprising a silica binder, wherein the binder comprises an aqueous silica sol having a SiO2/M2O mole ratio, wherein M represents the total of alkali metal and ammonium ions, of at least 6:1, and wherein after the primer coating has dried to the extent that it is touch dry, the coated substrate is immersed in water or alternatively kept in an atmosphere with a relative humidity of at least 50%.
    Type: Grant
    Filed: September 13, 2001
    Date of Patent: March 6, 2012
    Assignee: Akzo Nobel N.V.
    Inventors: Gerald Howard Davies, Gillian Diane Davies, legal representative, Paul Anthony Jackson
  • Primer coating of steel
    Patent number: 8048215
    Abstract: A process for primer coating steel which is intended to be fabricated and overcoated, in which process the steel is primer coated with a primer coating comprising a silica binder. The binder comprises alumina-stabilized aqueous silica sol and, optionally, a minor amount of alkali metal silicate. The binder has a SiO2/M2O mole ratio, wherein M represents the total of alkali metal and ammonium ions, of at least 6:1. After the primer coating has dried to the extent that it is touch dry, it is optionally treated with a solution which increases the film strength of the primer coating.
