EPOXY RESIN COATINGS
THE HUEY LONG BRIDGE HAS ALSO BEEN USED AS A PROVING GROUND FOR VARIOUS PROTECTIVE COATINGS ON STEEL. SEVERAL SERIES OF TEST PLATES WERE INSTALLED IN 1962 TO DEMONSTRATE THE RESISTANCE OF EPOXY RESIN COATINGS TO THE SALT BRINE EXPOSURE AT THIS LOCATION. IN 1966 ALL OF THE PLATES SHOWED ADVANCED COATING BREAKDOWN AS SHOWN BY THE RIGHT-HAND PLATE AND WERE REMOVED. EVEN THOUGH THESE EPOXY COATINGS DID NOT PROVE TO BE PARTICULARLY RESISTANT TO THIS EXPOSURE, A ZINC- RICH EPOXY COATING BECAME AVAILABLE IN 1965 AND TEST PLATES WERE INSTALLED AT THAT TIME. THIS IS A CATHODIC TYPE COATING AND AT LAST INSPECTION SHOWED NO EVIDENCE OF RUSTING, BLISTERING OR OTHER COATING FAILURE AND APPEARS TO BE VERY EFFECTIVE IN THIS SALT BRINE EXPOSURE. /ARTICLE/
