ISO 4624-2016 《Paints and varnishes -1 Pull -off test for adhesion》 Related products

The ISO 4624-2016 standard details methods for assessing the adhesion of paints, varnishes or other coatings by measuring their tensile stress in the vertical direction. This standard provides three different test methods for single-layer or multi-layer coating systems, designed to compare the adhesion performance of different coatings. Test results are influenced by a number of factors, including the Mechanical Properties of the coating system, the nature of the substrate, the coating method, drying conditions, and environmental factors. ISO 4624-2016 also emphasizes the importance of using sandwich structures to avoid substrate deformation. Together with ISO 2409, this standard provides an internationally recognized method for assessing the bonding properties of coatings.
