[0125] Example 3 - Curable Compositions and Coatings Prepared from the Polyepoxyester Resins of Synthesis Example 1

[0126] 10.000 g of polyepoxy ester resin from Example 1, 1.111 g of phenolic crosslinker (Methylon 75108), 0.016 g of catalyst (85% phosphoric acid), 0.013 g (BYK-310) additive, 26.666 g of monobutyl A mixture of glycol ether and 6.667 g cyclohexanone was stirred for 16 hours to form a clear solution. The clear solution was filtered through a 1-micron syringe filter, then coated onto tin-free steel (TFS) panels with a #20 coating bar. The resulting coated panels were dried and cured in an oven at 205°C for 15 minutes. The thickness of the cured coating was 5.4 microns.

[0128] 10.000 g of polyepoxy ester resin from Example 2, 1.111 g of phenolic crosslinker (Methylon 75108), 0.016 g of catalyst (85% phosphoric acid), 0.013 g (BYK-310) additive, 26.666 g of monobutyl ethyl A mixture of glycol ether and 6.667 g cyclohexanone was stirred for 16 hours to form a clear solution. The clear solution was filtered through a 1-micron syringe filter, then coated onto tin-free steel (TFS) panels with a #20 coating bar. The resulting coated panels were dried and cured in an oven at 205°C for 15 minutes. The thickness of the cured coating was 4.3 microns.

Abstract

A curable coating composition comprising an advanced poly epoxy ester resin polymeric composition having the following chemical structure: where n is a number from 1 to about 3000; each m independently has a value of 0 or 1; each R0 is independently -H or -CH3; each R1 is independently -H or a C1 to C6 alkylene radical (saturated divalent aliphatic hydrocarbon radical); Ar is a divalent aromatic fused -ring moiety, which is most preferably a divalent naphthalene group, substituted divalent naphthalene group, where the substitute groups include an alkyl, cycloalkyl, an aryl or an aralkyl group or other substituent; and X is cycloalkylene group, including substituted cycloalkylene group, where the substitute group include an alkyl, cycloalkyl, an aryl or an aralkyl group or other substitute group, for example, a halogen, a nitro, a blocked isocyanate, or an alkyloxy group; the combination of cycloalkylene and alkylene groups and the combination of alkylene and cycloalkylene group with a bridging moiety in between.

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional application claiming priority to US Provisional Patent Application 61 / 388,089, filed September 30, 2010, entitled "COATING COMPOSITIONS," the teachings of which are incorporated by reference into this application, as if reproduced in its entirety. technical field [0003] The present invention relates to a coating composition comprising a high molecular weight polyepoxy ester resin component prepared from an aromatic condensed ring dicarboxylic acid compound and an alicyclic diglycidyl ether compound. The coating compositions are useful, for example, as interior and exterior protective coating compositions for can bodies, and other metallic food and beverage packaging coatings. Background technique [0004] Epoxy resins are widely used in coating compositions for the interior and exterior surfaces of food and beverage containers as they offer a unique combination of properties of: ...
