Disclosed is a polyester polymer prepared from a reaction mixture comprising a polyacid component and a polyol component that comprises lignin. Residues of lignin are incorporated into the backbone of the polyester polymer. Coatings comprising the same and substrates coated at least in part with such coatings are also disclosed.

Polyester polymers comprising lignin

Disclosed are coating compositions that include a continuous phase that includes water and a dispersed phase that includes a microgel having a mean particle size of greater than 50 nanometers. The microgel is formed from reactants selected so as to provide a copolymer having a certain calculated Tg and includes a cycloaliphatic (meth)acrylate.

Waterborne coating compositions, related methods and coated substrates

Functional fluoropolymers and thermosetting compositions containing same

A process for forming and drying a multi-layer composite coating on an elongated three-dimensional multi-faced substrate is provided. The process includes the following steps: (1) passing the substrate to a first coating station located on a coating line; (2) applying a base coating composition to the entire exterior surface of the substrate as it passes through the first coating station, thereby forming a base coat on the substrate; (3) passing the substrate from step (2) to a first drying station located on the coating line; (4) drying the base coat as it passes through the first drying station; (5) passing the substrate from step (4) to a second coating station located on the coating line; (6) applying a top coating composition, different from the base coating composition, to at least one but not all of the faces of the substrate from step (5) as it passes through the second coating station to form a top coat on a portion of the substrate; (7) passing the substrate from step (6) to a second drying station located on the coating line; and (8) drying the top coat as it passes through the drying station. Substrates coated by the process of the present invention are useful as building components, for example window and door frames, where they provide one exterior-durable surface and one surface suitable as an interior surface.

Process for forming multi-layer coatings on three-dimensional multi-faced substrates and product made according to such process

A multi-layer composite coating composition is provided. The multi-layer composite coating composition includes an exterior-durable, organic solvent-borne base coating composition from which a durable base coating is deposited, and an aqueous top coating composition from which a top coating is deposited over at least a portion of the durable base coating. The multi-layer composite coating compositions are particularly useful as coatings for preformed, three-dimensional, multi-faced substrates employed in building construction, for example, the elongated extruded aluminum substrates used for window and door frames. Coated substrates are also provided.
