Learn how the amount of actual dispersant added on pigment solids will have an effect on tinting power, stability, compatibility of formulations, and other properties.
This article discusses some of the terms and calculations related to pigments used in coatings, including oil absorption/surface area; pigment volume concentration; and pigment to binder ratio.
Each pigment manufacturer optimizes particle size for the specific properties for that pigment grade. Hiding, tint strength, photo stability, viscosity and surfactant/resin demand are all affected differently by particle size.
