ActiveDetermination of matter soluble in water of pigments--Hot extraction method
颜料水溶物测定 热萃取法
Application Summary AI generated
This standard specifies the hot extraction method for determining the water-soluble matter content in pigments. It is applied in the paint, coating, and ink industries to assess pigment purity and quality, particularly for products where soluble salts can affect dispersion, stability, and final film performance. The test is conducted under controlled hot water conditions to simulate accelerated leaching during manufacturing or application.
