An aqueous ink composition for inkjet printing on non-porous substrates and a method for forming the same are disclosed. For example, the method includes preparing a primary polymer latex with an aromatic functional group, a hydrogen-bonding group, a flexible side-chain, and an ionic functional group and mixing the primary polymer latex with a secondary latex binder and one or more co-solvents.

The present application relates to a UV-LED curable coating composition, including: (a) at least one amine-modified polyether acrylate; (b) at least one (meth)acrylate polymer different from (a); (c) at least one multifunctional thiol compound; and (d) at least one acylphosphine oxide as a photoinitiator. In addition, the present application further relates to an article including a substrate partially or fully coated with the UV-LED curable coating composition.

Methods for forming a fluoropolymer coated component, such as a metal component, comprise applying an adhesion promoter onto a surface of the component; applying an organic material onto the adhesion promoter; and applying a mixture comprising a fluoropolymer and a solvent selected from a furan or a fluorinated solvent onto the organic material. Fluoropolymer coatings have a thickness of from about 5 mil to about 80 mil on a component, an average porosity of from about 20% to about 70% based on the total volume of the layer, and a void density of from about 10.sup.11 to about 10.sup.13 voids per cm.sup.3.
