EVALUATION OF ORGANIC ZINC COATINGS

THE PURPOSE WAS TO FIND A MORE ECONOMICAL AND TIME SAVING METHOD FOR COATING A STEEL BRIDGE. THIS WAS ACCOMPLISHED BY EVALUATING THE COST AND ACCELERATED LIFE OF AN ORGANIC ZINC PRIMER TOGETHER WITH ITS APPROPRIATE TOPCOAT VERSUS THE COST AND LIFE OF THE PRESENTLY USED BASIC LEAD SILICO CHROMATE COATING. FIVE GENERIC TYPES WITH THEIR RESPECTIVE TOPCOATS WERE STUDIED AND AN APPROVED QUALIFIED PRODUCTS LIST FOR EACH SYSTEM WAS MADE BASED ON THE RESULTS OF ACCELERATED EXPOSURES (SALT FOG AND WEATHEROMETER TESTS). /AUTHOR/
