Patent number: 6270884Abstract: There is disclosed a water-reducible, chrome-free coating composition for providing corrosion protection to a substrate, such as a metal substrate. The deposited coating film is corrosion-resistant and, for coated articles which are threaded, e.g., steel fasteners, the coating provides a non-thread-filling coating. The coating composition contains particulate metal, such as particulate zinc or aluminum. Although substituents can be separately packaged, the composition is virtually always a one-package coating composition. The composition is water-based, while also containing low-boiling organic liquid. The composition also contains water-reducible organofunctional silane, particularly an epoxy functional silane, as a binding agent. The composition has highly desirable, extended shelf life. The composition can be easily applied in usual manner, such as dip-drain or dip-spin technique, and readily cures at elevated temperature.Type: GrantFiled: August 2, 1999Date of Patent: August 7, 2001Assignee: Metal Coatings International Inc.Inventors: Donald J.

Patent number: 5006597Abstract: The present invention relates particularly to a one-package, black-pigmented, corrosion resistant coating composition, of excellent storage stability and being especially suitable for application over metal that has been coated with a composition containing chromium in non-elemental form. More specifically, the coating composition of the invention is formulated from an intimate blend of aqueous carbon black colloidal dispersion in aqueous medium, which is in further mixture with thickening agent aqueous acrylic resin dispersion and silica sol having a pH of not above about 10.Type: GrantFiled: June 12, 1989Date of Patent: April 9, 1991Assignee: Metal Coatings International Inc.Inventors: Arthur A.

Patent number: 4971635Abstract: A coating composition is now provided which can have a great number of desirable coating characteristics, when the composition is applied and cured on a metal substrate. Moreover, the coating composition has applicability to a great variety of metal substrates. Such substrates include base metal such as steel as well as metal coated substrates such as zinc electroplated steel. Furthermore, the coating compositions can be useful when applied to substrates sensitive to elevated cure temperature, e.g., annealed steel. In one important aspect the composition can contain hexavalent-chromium-providing substance in mixture with cobalt compound. Particulate metal may be present in the composition. A composition furthermore most desirably contains a special organic acid/alcohol reducing agent combination for the hexavalent chromium. The composition can provide a low-cure coating on a metal substrate, which can then translate into higher production line speeds as when used for coating of metal coils.Type: GrantFiled: July 1, 1988Date of Patent: November 20, 1990Inventors: Donald J.
