The ISO 21545:2018 standard specifies methods for the determination of Paints and varnish sedimentation. Sedimentation refers to the settling phenomenon of solid particles in Coatings during storage or standing, which affects the uniformity and performance of Coatings. The standard provides a technical method for measuring the amount of Coating sedimentation by specific equipment and experimental conditions. During the determination, the sample is placed in a standard container and the sedimentation phenomenon is observed and recorded for a specified time. This method is suitable for evaluating the Stability and usability of Coatings, especially for Coatings containing large particulate matter, such as pigments, fillers, etc. By implementing this standard, manufacturers and users can effectively monitor the mass of coatings and ensure their performance and Appearance conformity in actual use.
