A stable, aqueous barrier coating composition includes: (a) prolamine; (b) cold water insoluble polymer; (c) water; (d) water-soluble co-solvent; and (e) stabilizer. The composition, when applied to a substrate, produces an article having a high surface energy and resistance to oil and grease penetration. A method of producing the article involves applying the composition to a substrate.

Environmentally Friendly Adhesive Bonding for Composites, Pollutant Remediation, and Dye Decolorization
PROBLEM: Environmentally friendly methods are needed to bond wood products and other composites without formaldehyde. Organic pollutants and dyes from textile and paper plants in industrial wastestreams need remediation.
SOLUTION: Using the chemically enhanced Fenton system, dyes can be remediated quickly in an environmentally safe manner. Natural lignin from wood residues can be activated to produce an formaldehyde-free adhesive system and organic pollutants in waters or soils can be broken down.
