The ASTM D 2369-24 standard specifies a test method for determining the volatile content of Coatings. This method measures the volatile weight percentage of solvent-type and water-based paints by heating the sample at 110 +/- 5 ° C for 60 minutes. It is suitable for various Coating systems, including air drying, heat curing, etc. The test process involves heating the sample and recording the loss of volatiles. This method is suitable for multi-component Coatings, but if the sample is abnormal during heating analysis, the time and temperature need to be adjusted according to the actual production situation.
