ASTM D869-21 Standard Test Method for Evaluating Coating Sedimentation Degree specifies an experimental method for evaluating Coating sedimentation Degree. This method is designed to evaluate the distribution of pigment and Miscellaneous solids in Coatings by observing the sedimentation phenomenon of Coatings after standing. Stability and mass of Coatings are judged by placing Coatings in specified containers and measuring the degree of sedimentation of solids in Coatings after a certain period of time. The evaluation of sedimentation degree helps manufacturers control the formulation and production process of Coatings to ensure that Coatings do not experience delamination or settling during storage and use. This standard is widely applicable to a wide range of coatings products, including industrial coatings, architectural coatings, etc., to help the industry ensure the uniformity and Stability of coatings.
