The ASTM D 2698-05 (2022) Standard Test Method for the Determination of Pigment Content in Solvent Reducing Coatings by High Speed Centrifugation specifies an experimental method for the determination of pigment content in solvent reducing coatings by high speed centrifugation. This method uses different sedimentation rates of pigment and solvent to quantify pigment content by centrifuging a Coating sample in a high speed Centrifuge. This standard is applicable to solvent reducing coatings, particularly for evaluating pigment dispersion and concentration in Coating formulations. Through this method, accurate pigment content data can be obtained, which helps Coating manufacturers to optimize product formulations and ensure Coating mass and conformity. The standard describes the operation process, equipment requirements and calculation methods in detail to ensure the Reliability and repeatability of test results. This method is suitable for quality control and research analysis, providing a scientific and effective detection method for Coating production and related fields.
