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 month's Formulating with Mike column discusses the development of surfactant molecules for use as a carbon black pigment dispersant. 

This column covers how to go about selecting the right resin for your coating.

This column covers discuss the robustness of a coatings system in reference to pigment dispersion.

This column covers pigment dispersion procedures.

This column covers high-speed dispersion as an option for pigment dispersion.

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.

This month’s Formulating with Mike column discusses how light and pigment interactions affect hiding, tint strength and other properties of a coating.
