Abstract

Liquid jet or aerosol jet coating compositions, coated coil substrates, and methods of coating a coil substrate are disclosed. The method may include directing a liquid jet or aerosol jet coating composition to at least a portion of the coil substrate. The liquid jet or aerosol jet coating composition may include polymer particles and a liquid carrier including water in a major amount of the liquid carrier. The method may include providing conditions effective for the liquid jet or aerosol jet coating composition to form a hardened continuous adherent coating on at least a portion of the coil substrate.

First claim

1 . A method of coating a coil substrate, the method comprising:
directing a liquid jet or aerosol jet coating composition to at least a portion of the coil substrate, the liquid jet or aerosol jet coating composition comprising:
polymer particles comprising a polymer having a number average molecular weight of at least 2000 Daltons, wherein the polymer particles have a particle size distribution having a D50 of less than 10 microns; and
a liquid carrier comprising water in a major amount of the liquid carrier; and
providing conditions effective for the liquid jet or aerosol jet coating composition to form a hardened continuous adherent coating on at least a portion of the coil substrate.

2 . The method of claim 1 , wherein the liquid jet or aerosol jet coating composition comprises:
polymer particles comprising a polymer having a number average molecular weight of at least 2000 Daltons, wherein the polymer particles have a particle size distribution having a D50 of less than 10 microns; and a liquid carrier comprising water in a major amount of the liquid carrier.

3 . The method of claim 1 , wherein the polymer particles have a particle size distribution having a D50 of less than 5 microns.

4 . The method of claim 1 , wherein the polymer particles comprise a thermoplastic polymer, optionally wherein the polymer particles comprise a polymer selected from a polyacrylic, polyether, polyolefin, polyester, polyurethane, polycarbonate, polystyrene, or a combination thereof.

5 . The method of claim 1 , wherein the directing comprises selectively applying the liquid jet or aerosol jet coating composition to at least a portion of the coil substrate to form a patterned coating.

6 . The method of claim 1 , further comprising providing multiple liquid jet or aerosol jet coating compositions, wherein at least two of the multiple liquid jet or aerosol jet coating compositions are different and wherein at least one coating composition is deposited on another different coating composition.

7 . A coated coil substrate comprising a coil having a surface at least partially coated with a coating prepared by the method of claim 1 .

8 . The coated coil substrate of claim 7 , wherein the coil substrate comprises aluminum, iron, copper, tin, steel, an alloy thereof, or a combination thereof.

9 . The coated coil substrate of claim 7 , wherein the coil substrate has an average thickness of 300 μm or greater.

10 . The coated coil substrate of claim 7 , wherein the coating comprises a hardened adherent coating.

11 . The coated coil substrate of claim 7 , wherein the coating has an average thickness of at least 1 micron.

12 . The coated coil substrate of claim 7 , wherein the substrate is a drawn and redrawn substrate.

13 . The coated coil substrate of claim 7 , wherein the coating comprises two or more layers.

14 . An article comprising a coil substrate having a surface at least partially coated with a coating prepared by the method of claim 1 .

15 . The article of claim 9 , wherein the coil substrate is formed into a building panel, a metal roof panel, a wall panel, a garage door, office furniture, a home appliance, a heating or cooling panel, an automotive panel or part, or an architectural metal skin.
