COATINGS ADHERENCE MEASUREMENT BY AN ANGULAR SCRIBE- STRIPPING TECHNIQUE

ADHESION IS OF FUNDAMENTAL IMPORTANCE TO THE PERFORMANCE OF APPLIED ORGANIC COATINGS, AND YET THERE HAS BEEN NO SATISFACTORY METHOD FOR MEASURING THIS PROPERTY QUANTITATIVELY AND UNAMBIGUOUSLY ON PRACTICAL SUBSTRATES. PRACTICAL MEASUREMENTS ARE BEING MADE OF COATING-SUBSTRATE ADHERENCE, USING A SIMPLE ANGULAR SCRIBE-STRIPPING TECHNIQUE SUITABLE FOR EITHER THE LABORATORY OR THE FIELD. EXPERIMENTAL INVESTIGATIONS HAVE BEEN CONFINED TO METAL PROTECTIVE SYSTEMS, HOWEVER, THE METHOD MAY BE APPLICABLE TO COATINGS ON CERTAIN NONMETALLIC SUBSTRATES. THE TECHNIQUE YIELDS A DIMENSIONLESS ADHERENCE NUMBER THAT IS INDEPENDENT OF FILM THICKNESS, IS RELATIVELY INSENSITIVE TO OTHER FILM PROPERTIES, AND CORRELATES VERY WELL WITH ADHERENCE RANKINGS DETERMINED BY THE QUALITATIVE KNIFE TEST.
