DIN 53163-1988 《Testing of pigments and extenders; determination of lightness of extenders and white pigments in powder form》 Related products

The DIN 53163-1988 standard specifies the determination method of transparency for filler powder and white pigment powder, which is suitable for evaluating the application performance of these powder materials in Coatings, plastics, paper and other products. This method measures the light scattering and covering ability of the powder by testing the transparency, providing a basis for the selection of suitable filler or pigment. The standard details the specific requirements for sample preparation, instrument calibrating, measurement conditions and result analysis, ensuring the accuracy and repeatability of the test. The determination of transparency is an important indicator for evaluating the mass of the powder and its interaction with the substrate, which helps to optimize the formulation design and improve the performance of the final product. This standard provides scientific basis and technical guidance for quality control and research and development in related industries.
