GB/T 5211.12-2007
ActiveDetermination of resistivity of aqueous extract pigments
颜料水萃取液电阻率的测定
Application Summary AI generated
This standard specifies a method for measuring the electrical resistivity of the aqueous extract from pigments, which indicates the concentration of water-soluble ionic impurities. It is applied in the paint, coating, and plastics industries to assess pigment purity and predict potential corrosion or performance issues in water-based systems. The test is used for quality control of pigments and extenders, particularly in formulations where high resistivity is critical, such as in electrodeposition coatings or electronic applications.
