BYK-Gardner Grind Gages
BYK-Gardner Grind Gages are testing instruments used to evaluate fineness of grind and detect the presence of coarse particles or agglomerates in dispersions. These instruments are essential for ensuring that pigments, fillers, extenders, and other solid particles are properly dispersed in paints, coatings, inks, varnishes, resins, pastes, and other liquid or semi-solid materials.
In coating, ink, and pigment dispersion production, grind quality directly affects color strength, gloss, opacity, hiding power, surface smoothness, stability, and final product appearance. A dispersion that still contains coarse particles or agglomerates may cause defects such as rough surfaces, poor gloss, weak color development, sedimentation, clogging during application, or non-uniform coating results.
BYK-Gardner Grind Gages consist of a steel block with one or more grooves that gradually decrease in depth from the deepest end to zero. The sample is placed at the deepest part of the groove, then drawn down with a scraper to form a thin film. The point where coarse particles or speckle patterns appear is used as the grind reading on microns, mils, Hegman, or NPIRI scales depending on the gage type. This category is suitable for quality control, R&D, formulation development, milling process control, batch comparison, pigment dispersion evaluation, and testing according to ASTM D1210 and ISO 1524.
