WebCoating Adhesion Testing Applied Technical Services offers coating adhesion testing to clients looking to determine the adhesive value of their coatings. Our services adhere to the American Society for Testing & Materials (ASTM) international standards. The PosiTest AT Adhesion Tester is DeFelsko's solution for accurately performing a coating adhesion test. Available in both Manual (PosiTest AT-M) and Automatic (PosiTest AT-A) models, the pull-off adhesion tester measures adhesion of coatings to metal, wood, concrete, and other rigid substrates. See more This simple test requires the use of a utility knife to pick at the coating. It establishes whether the adhesion of a coating to a substrate or to another coating (in multi-coat systems) is at a generally adequate level. Performance is … See more On metal substrates, a more formal version of the knife test is the tape test. Pressure sensitive tape is applied and removed over cuts made in the coating. There are two … See more A scrape test is typically performed in a laboratory and is limited to testing on smooth, flat panel surfaces. Adhesion is determined by pushing the coated panels beneath a rounded stylus or loop that is loaded in increasing … See more A more quantitative test for adhesion is the pull-off test where a loading fixture, commonly called a dolly or stub, is affixed by an adhesive to a … See more

WebThe adhesion of coatings to substrates can be determined qualitatively or quantitatively depending on the test method used. Various other methods have also been developed to study adhesion phenomena, such as scratching (Thouless, 1998) and indenting ( Marshall and Evans, 1984) the surface of the coating. WebApr 1, 2024 · The article presents the hybrid metaheuristic-neural assessment of the pull-off adhesion in existing multi-layer cement composites using artificial neural networks (ANNs) and the imperialist competitive algorithm (ICA). The ICA is a metaheuristic algorithm inspired by the human political-social evolution. This method is based solely on the use of ANNs …
