摘要： There is disclosed a water-reducible, chromium-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 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 the usual manner, such as dip-drain or dip-spin technique, and readily cures at elevated temperature.

摘要： Composite coatings, of an undercoating plus a subsequent coating each containing a multi-valent metal, can achieve excellent corrosion protection when the coatings are subjected to appropriate heat curing. Such curing for a subsequent coating is generally under conditions unlike those of a similar, or the same, undercoating. Firstly, control over cure temperature and time is exercised with the undercoating to virtually eliminate its water sensitivity. Then for example, water quenching may be used in cooling. Next, differing cure conditions for the topcoating are used to favor augmented corrosion resistance for the composite.

摘要： 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.
