The present invention relates to an article comprising metal coated with an aqueous dispersion of polyolefin particles as well as metal coated with a polyolefin film arising from this dispersion. More particularly the polyolefin particles of the present invention are predominantly polypropylene particles.

Metal coated with a functional polypropylene film

The present disclosure provides for an aqueous dispersion for use in coating applications. The aqueous dispersion includes an aqueous composition and a solid content of a melt blend product having an acid functionalized polypropylene base polymer, a polypropylene copolymer, an acid functionalized polypropylene wax and an acid functionalized polyolefin. The aqueous dispersion is included in a coating composition, where the coating composition includes the aqueous dispersion, a solvent, a crosslinker and a basic water composition having water and a base. The present disclosure also provides for a coated article having a substrate and a coating on the substrate, where the coating includes the coating composition of the present disclosure.

Coating compositions

The present invention provides aqueous polyolefin dispersion compositions for use in metal coatings, such as can coatings, comprising one or more polyolefin base polymer, one or more at least partially neutralized olefinic stabilizing agent having an acid number (AN) of from 80 to 250, preferably, a polyolefin stabilizing agent, such as an olefin-carboxylic acid copolymer or a blend of two such polymers, an optional coupling agent having an acid number (AN) of from 10 to 70 and a melt index of from 500 to 5,000,000 grams of polymer melt passing in 10 minutes through a heated syringe or cylinder at 190&#xb0; C. with a plunger loaded with 2.16 kg, preferably, a polymer, and a hindered phenolic antioxidant containing an ester linkage dispersed in the polyolefin dispersion composition. The hindered phenolic antioxidant containing an ester linkage can be masterbatched with a polyolefin base polymer, polyolefin stabilizing agent or a coupling agent which is a polymer, melt mixed with the remaining polyolefin composition and then dispersed with aqueous media and a neutralizing agent to form the aqueous dispersion.

Water borne polyolefin dispersion coatings, and methods of making

The instant invention provides a polyester composition, method of producing the same, coating compositions made therefrom, and coating layers made from such coatings. The thermoset polyester composition according to the present inventions comprises the reaction product of: (a) one or more polyacids comprising at least 50 percent by the combined weight of one or more aromatic diacids; and (b) one or more polyols comprising at least 40 percent by the combined weight of 1,4-cyclohexanedimethanol and 2,2,4,4-tetramethylcyclobutanediol; wherein said polyester composition has a glass transition temperature in the range of from 70 to 125&#xb0; C., a number average molecular weight between 6,000 and 20,000, a hydroxyl number in the range of from 4 to 18.
