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.
