Abstract

A coating composition comprising an advanced epoxy resin polymeric composition having the following chemical structure:(formula) I 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); R′1-R′4 are independently hydrogen, an alkyl, cycloalkyl, an aryl or an aralkyl group or other substituent, for example, a nitro, an isocyanate, or an alkyloxy group; additionally, any two of R′1-R′4 may form fused ring independently; and X is cycloalkylene group, including substituted cycloalkylene group, where the substituent groups include an alkyl, cycloalkyl, an aryl or an aralkyl group or other substituent group, for example, a halide, a cyano, 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.
