Abstract
Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by dip, spray or flow coating. The methods can make coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In some methods, the aqueous solutions, dispersions, or emulsions are substantially or completely free of VOCs.
Claims47
A coated article comprising
- a gas barrier layer comprising one or more of a vinyl alcohol polymer or copolymer and a Phenoxy-type Thermoplastic;
- and
- a water-resistant coating layer comprising a water-resistant material, wherein the material comprises one or more selected from the group consisting of an acrylic polymer or copolymer, a polyolefin polymer or copolymer, a polyurethane, an epoxy polymer, and a wax.
The coated article of claim 18, wherein the water-resistant coating layer comprises EAA.
A method for reducing the water and gas permeability of an article substrate, the method comprising:
- applying a first water-based solution, dispersion, or emulsion of a gas barrier material comprising one or more selected from a vinyl alcohol polymer or copolymer and a Phenoxy-type Thermoplastic to a surface of an article substrate by dip, spray or flow coating to form a first inner coating layer;
- drying the first inner coating layer.
- applying a second water-based solution, dispersion or emulsion of a water-resistant coating material comprising one or more selected from the group consisting of an acrylic polymer or copolymer, a polyolefin polymer or copolymer, a polyurethane, an epoxy polymer, and a wax to an outer surface of the article by dip, spray or flow coating to form a second coating layer,
- drying the second coating layer.
