ASTM D564-87 (2023) Standard Test Method for Liquid Coating dryers specifies a test method for evaluating the performance of liquid Coating drying agents. The standard details the process for determining Coating drying time, including sample preparation, Coating thickness control, drying condition setting, and result recording and evaluation criteria. These methods allow users to understand the effectiveness of different drying agents in promoting Coating curing and performance improvement, thereby optimizing formulations and applications. This standard is applicable to laboratory research, product development and quality control in the production process, providing scientific and reliable technical support for the Coatings industry to ensure that the final product meets performance requirements and adapts to market demand.
