The ISO 16482-2:2013 standard specifies a method for the determination of non-volatile matter content in aqueous rosin Resin dispersion using a microwave method. This method is suitable for aqueous rosin Resin dispersion in Coating and varnish. The volatile components in the sample are rapidly evaporated by microwave heating technology to measure the content of non-volatile matter. The microwave method has higher test efficiency and accuracy than the traditional oven method, which can reduce the heating time and improve the repeatability of the experiment. This standard provides the Coating industry with a modern, fast and reliable detection method, ensuring the quality control and performance Stability of waterborne rosin Resin products.
