Why should you view this course?

Today, pigment dispersion is a central question for coatings & inks formulators and it requires deeper and deeper expertise to efficiently develop / optimize high-solids, powder and water-based systems or to benefit from nanotechnology.

  1. Analyze faster cause of problems with a comprehensive review of factors impacting stabilization: pigments, equipment, anchor sites, repulsions…
  2. Forget about trials & errors & gain in speed – Opt directly for solutions properly addressing issues at their root causes ( wetting, separation, settling... )
  3. Better select ingredients (pigments, fillers, dispersants, wetting agents...) by learning about simple tests to predict final performance
Introduction to Pigment Dispersion & Stabilization- Part 2

Who should view this course?

Ideally suited for all those who use, formulate, produce, specify and market products based on pigments and fillers.

Very good information on stabilization theory and practical information.

Neil B. , from Hewlett Packard

Excellent course! It was interesting to learn about the anchoring stabilization and failure.

Amanda P. , from Interplastic Corporation

It explained the topics at a basic level and then went into further detail. The mechanisms were greatly appreciated (the "why").
