The ASTM D5895-20 standard test method is used to evaluate the drying or curing process of organic coatings during film formation. Mechanical recorders are used for testing. This method provides important data on Coatings performance by recording changes in the coating surface during drying or curing. The standard defines how to use mechanical recorders to monitor the drying rate, degree of curing, and Miscellaneous key performance indicators of coatings under specific environment conditions. The testing process not only helps to study the curing behavior of coatings, but also provides reliable technical support for the production and application of Coatings. This method is suitable for the evaluation of various organic coatings, including paints, varnishes, and Miscellaneous coatings.
