Ultraviolet curable coatings—Determination of volatile content

GB/T 33374-2016 "Ultraviolet Curing Coatings—Determination of Volatile Matter Content" is applicable to the determination of volatile matter content in ultraviolet curing coatings. The method involves accurately weighing the sample using an analytical balance, heating the sample in a constant-temperature oven to a specified temperature and maintaining it, and calculating the volatile matter content based on the mass difference before and after heating. Alternatively, gas chromatography can be used for qualitative and quantitative analysis of volatile components. The standard specifies requirements for oven temperature, holding time, and sample quantity, providing a standardized method for controlling the environmental performance of ultraviolet curing coatings.
