Assessing the Result; Glue, Adhesive and Cohesive Failures When testing coating adhesion using a pull-off adhesion gauge, typically the dolly, or pull stub, is completely pulled off the surface, and you . 1 These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing 1. The adhesion of a coating to a substrate is typically affected by the cleanliness of the surface and the profile, such as International Standard ISO 4624 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. dolly. This handbook elaborates the different testing methods of paints with an understanding of the various tests that can be performed on product performance.
