ISO 8781-2-1990 《Pigments and extenders - Methods of assessment of dispersion characteristics - Part 2: Assessment from the change in fineness of grind》 Related products

The ISO 8781-2-1990 standard provides a method for evaluating the dispersion characteristics of pigments, with an emphasis on variations in fineness of ground. By preparing pigment dispersion in a gluing agent system and measuring its fineness of ground, the standard helps determine the ease of operation of pigments during dispersion. This method involves preparing a series of pigment dispersions, measuring their final fineness of ground, and assessing the ease of achieving this fineness. This evaluation method is often used to compare the dispersion characteristics of similar pigments, ensuring that pigments can achieve the desired fineness and uniformity in practical applications.
