Particle size, particle shape, and the concentration of ingredients and additives affect the behavior, coverage, vibrance, and longevity of ink, pigments and paints. Because ink and pigments are used in everything from commercial printing presses to textiles and powder coating to household paints and stains, the material behavior of ink and pigments is crucial to a wide variety of industries and applications.

Analysis of the particles that make up the ingredients of a formulation play a vital role in determining important material behaviors, including longevity, smudge resistance, and how well an ink will apply and adhere, among others. From testing the raw materials before formulation through stabilization studies of the final product, particle size and characterization of inks and pigments provide invaluable information which can assist in yielding optimum performance.

Particle Technology Labs has worked with clients through each stage of the process, from raw material suppliers to formulation chemists to end users. PTL conducts particle size and characterization testing to troubleshoot and verify materials, providing accurate test results and ensuring the quality and integrity of materials used in the ink, paint and pigment industries.
