POLYESTER COMPOSITIONS FOR METAL PACKAGING COATINGS

This invention pertains to improved polyester polyol compositions containing 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD). Coating compositions based on such TMCD polyester polyols are capable of providing a good balance of desirable coating properties such as solvent resistance, acid resistance,...

Zusammenfassung:	This invention pertains to improved polyester polyol compositions containing 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD). Coating compositions based on such TMCD polyester polyols are capable of providing a good balance of desirable coating properties such as solvent resistance, acid resistance, retort resistance, microcracking resistance, and bending ability. The TMCD coating compositions have particular utility for use in metal packaging applications.
