ISO 3678-1976 Paints and varnishes without imprinting test is a standard published by the international standards organization to assess the ability of coatings, varnishes or related products to resist imprinting during the drying process. The standard specifies a simple experimental method to observe whether coatings leave imprints by placing a nylon screen on the surface of the coating and applying a specific weight. Testing can be carried out after coating drying or stoving and is suitable for a wide range of Coating types. The standard emphasises the uniformity of test conditions to ensure comparability and accuracy of results. This test provides an important quality control basis for the Coatings industry to ensure the performance of the product in practical applications.
