Coating compositions containing epoxy resins and carboxyl terminated polyesters
Abstract
Abstract IMPROVED COATING COMPOSITIONS COMPRISING A BLEND OF AN EPOXY RESIN AND A POLYESTER HAVING A TERMINAL CARBOXYL FUNCTIONALITY BETWEEN BOUT TWO AND FOUR. THE PREFERRED POLYESTER IS THE ESTERIFICATION PRODUCT OF (1) A HYDROXYL TERMINATED POLYESTER AND (2) A CARBOXYLIC ACID-CONTAINING MONOANHYDRIDE COMPOSITION MADE UP OF A MIXTURE OF TRIMELITIC ANHYDRIDE AND DODECNYLSUCCINIC ANHYDRIDE. CARTERING OF COATINGS HAS BEEN VERY SUBSTANTIALLY REDUCED BY USED OF TERMINALLY LOCATED DODECENYLSUCCINIC ANHYDRIDE-PRODUCED SIDE CHAINS ON THE POLYESTER. CRATERING IS STILL FURTHER REDUCED AND SOLUBILITY PARAMETERS ARE IMPROVED BY EMPOLYING A GLYCIDYL ESTER OF A TERTIARY CARBOXYLIC ACID, SUCH AS CARDURA E, IN THE PREPARATION OF THE HYDROXYL TERMINATED POLYESTER.
