Abstract
Described herein is a coated article comprising a substrate, a coil coating applied to the substrate, the coil coating comprising a base coat layer formed from a base coat composition comprising polyester that is substantially free of silicon; a print coat layer formed from a print coat composition comprising siliconized polyester; and a top coat layer formed from a top coat composition comprising siliconized polyester.
Claims20
A coated article comprising
- a substrate;
- a coil coating applied to the substrate, the coil coating comprising:
- a base coat layer formed from a base coat composition comprising polyester that is substantially free of silicon;
- a print coat layer formed from a print coat composition comprising siliconized polyester;
- and
- a top coat layer formed from a top coat composition comprising siliconized polyester.
A coated article comprising a first major exposed surface opposite a second major exposed surface, the coated article comprising:
- a substrate comprising an upper surface opposite a lower surface;
- a coil coating applied to the substrate, the coil coating having an upper surface opposite a lower surface and the coil coating comprising:
- a primer coat layer comprising an upper surface opposite a lower surface, the primer layer formed from a primer composition that is substantially free of chromium;
- a base coat layer comprising an upper surface opposite a lower surface, the base coat layer formed from a base coat composition comprising polyester that is substantially free of silicon;
- a print coat layer comprising an upper surface opposite a lower surface, the print coat layer formed from a print coat composition comprising siliconized polyester;
- and
- a top coat layer comprising an upper surface opposite a lower surface, the top coat layer formed from atop coat composition comprising siliconized polyester;
- and
- wherein the first major exposed surface of the coated article comprises the upper surface of the top coat layer.
A method of forming a coated article comprising:
- a) applying a wet-state primer coating composition comprising a liquid carrier to a substrate and drying the wet-state primer coating composition that is applied to the substrate such that the liquid carrier of the wet-state primer coating composition is evaporated resulting in a primer coating layer;
- b) applying a wet-state base coating composition comprising a liquid carrier to the primer coating layer and drying the wet-state base coating composition that is applied to the primer coating layer such that the liquid carrier of the wet-state base coating composition is evaporated resulting in a base coating layer;
- c) applying a wet-state print coating composition comprising a liquid carrier to the base coating layer and drying the wet-state print coating composition that is applied to the base coating layer such that the liquid carrier of the wet-state print coating composition is evaporated resulting in a print coating layer;
- d) applying a wet-state top coating composition comprising a liquid carrier to the print coating layer and drying the wet-state top coating composition that is applied to the print coating layer such that the liquid carrier of the wet-state top coating composition is evaporated resulting in a top coating layer;
- and
- wherein the wet-state base coating composition further comprises an organic polymer that is substantially free of silicon;
- wherein the wet-state print coating composition further comprises siliconized organic polymer;
- and
- wherein the wet-state top coating composition further comprises siliconized organic polymer.
