Corrosion-inhibiting coating compositions which are self-priming topcoats having improved weatherability and durability are provided. The compositions contain fluorinated resins (binders), incorporate one or more corrosion-inhibiting compounds including corrosion-inhibiting extenders (a metal cation from Group I A or II A of the periodic table of the elements and an oxyanion counterion), corrosion-inhibiting rare earth compounds, and corrosion-inhibiting carbon pigments. Methods for applying the corrosion-inhibiting compositions to a substrate are also provided.
Water-Reducible Epoxy Coating Compositions Without Emulsifier
A homogeneous, water-reducible coating composition comprises a modified polyamine resin homogeneously reduced, in an aqueous system comprising water and a low-molecular weight nitroparaffin. An epoxy resin can be added to the coating composition to form a stable emulsion.

Amino Alcohol Treatment For Sol-Gel Conversion Coatings, Substrates Including The Same, And Methods Of Making The Substrates
An article includes a substrate, a sol-gel conversion coating on at least a portion of the substrate, and a treatment layer on at least a portion of the sol-gel conversion coating. The treatment layer includes an amino alcohol. A method of manufacturing the article includes applying a partially cured sol-gel composition to at least a portion of a substrate, at least partially drying the partially cured sol-gel composition to form the sol-gel conversion coating, applying a solution including an amino alcohol to at least a portion of the sol-gel conversion coating, and at least partially drying the solution including the amino alcohol.
