IDENTIFICATION OF WEATHERED PAINTS BY INFRARED SPECTROSCOPY

IN A RECENT NAVAL CIVIL ENGINEERING LABORATORY STUDY, INFRARED SPECTROSCOPY, SOMETIMES IN CONJUNCTION WITH VISUAL OBSERVATIONS, SOLUBILITY TESTS, AND SPOT CHEMICAL TESTS, WAS SUCCESSFULLY UTILIZED TO DETERMINE THAT SUBSTITUTE PAINTS HAD BEEN USED INSTEAD OF THOSE SPECIFIED. REMEDIAL ACTION OR A CASH SETTLEMENT WAS MADE BY THE CONTRACTOR. BAND READINGS AND OTHER METHODS OF DETECTION ARE INCLUDED IN THIS ARTICLE FOR DRYING OIL PAINTS, ALKYDS, CATALYZED POLYESTERS, AND COAL TAR AND ASPHALT COATINGS. CHARACTERISTIC BANDS FOR EPOXIES, COAL TAR EPOXIES, AND CATALYZED URETHANES ARE ALSO INCLUDED. THE LARGE NUMBER OF DIFFERENT MIXED POLYMER VARIATIONS OF VINYL FORMULATIONS CAUSES THEIR IDENTIFICATION IN A WEATHERED PAINT TO BE MOST DIFFICULT. /AUTHOR/
