The NF T30-418-2-2016 standard specifies a method for the determination of non-volatile matter content in aqueous rosin Resin dispersion, which is analyzed by microwave method. This method is suitable for gluing agents for coating and varnish, especially aqueous rosin Resin dispersion. The content of non-volatile matter in samples is quickly and accurately determined by microwave heating technology. The standard describes in detail the operation steps, instrument requirements, sample preparation and data analysis methods of the microwave method. Through this test, the mass of the coating gluing agent can be effectively controlled to ensure the performance Stability and environmental friendliness of the coating. The method has the advantages of fast and simple, and is suitable for inspection and quality control of Resin dispersion mass in the Coating industry.
