Abstract
This invention provides a polymer, which is preferably a polyether polymer. The polymer may be used in coating compositions. Containers and other articles comprising the polymer and methods of making such containers and other articles are also provided. The invention further provides compositions including the polymer (e.g., powder coatings), which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.
Claims26
1-33. (canceled)
A coating composition comprising:
- at least 10 wt-%, based on total resin solids, of a polyether polymer having a number average molecular weight of at least 2,000 and a glass transition temperature of at least 60° C., the polyether polymer formed by reacting:
- (i) an extender and (ii) an aliphatic diepoxide compound;
- wherein the polyether polymer does not include any structural units derived from bisphenol A, bisphenol F, bisphenol S, or any diepoxides thereof, and
- wherein the coating composition is an interior food or beverage container coating composition.
