This standard specifies a method for the determination of the paraffin resistance of pigments. The paraffin resistance of pigments refers to the ability of pigments to resist the dissolving action of paraffin in molten paraffin wax to prevent the staining phenomenon of paraffin wax. Stability of pigments in paraffin wax is evaluated by contact with pigments and paraffin wax. The required materials and instruments are listed in detail in the standard, including toner, paraffin wax, printing paper, etc., as well as the specific steps and conditions required for testing. This method provides an important basis for the evaluation of pigment performance and helps to ensure the Reliability and durability of pigments in practical applications.
