GB/T 1725-2007 《Paints,varnishes and plastics - Determination of non-volatile-matter content》 Related products

GB/T 1725-2007 "Determination of non-volatile-matter content of Paints, varnishes and plastics" specifies methods for determining the non-volatile-matter content of Paints, varnishes, Paints and varnishes, polymer dispersion and polyester resins such as phenolic resins. This standard is proposed by the Chinese Chemical and Petrochemicals Association and is suitable for evaluating non-volatile-matter content in Coatings and plastics. The standard covers the use of oven heating methods to determine the mass percentage of non-volatile matter by accurately weighing and heating samples. These methods help ensure that coatings and plastic products do not release unwanted volatiles during use, helping to ensure mass and environment safety.
