Course Description

Strengthen your core fundamentals w.r.t pigment dispersion & stabilization to identify the root causes of your problems faster (ingredients or process?).

In this course, Our expert consultant Jochum Beetsma will help you troubleshoot poor pigment dispersion cases (color strength, hiding power, paint stability, conductivity, corrosion resistance…). The underlying science (pigment dispersion process & factors influencing it), ingredients selection, key concepts (pigment wetting, capillary flow…) will be discussed in detail.

Why should you view this course?

Understanding the science behind dispersion issues makes it easier to decide whether to adjust your ingredients or optimize your process. That’s the key to unlocking stable, high-performance formulations. Join this course to:

  1. Analyze faster the cause of problems with a comprehensive review of factors impacting stabilization: pigments, equipment, anchor sites, repulsions…

  2. Eliminate trials & errors by directly applying solutions that properly address issues at their root causes (wetting, separation, settling…).

  3. Better select ingredients (pigments, fillers, dispersing agents for paint, wetting agents…) by learning about simple tests to predict final performance.

Who should join this course?

  • Formulators, Pigment & Filler Producers & Users: This course is right for you if you use or sell pigments & fillers and need a performance boost to get ahead of the crowd. (Few in the industry master these crucial foundations)

  • Complete the course and (unlock your personalized certificate)– your badge of accomplishment awaits!

  • This course is suitable for beginner level proficiency

Questions you will be able to answer after this course:

  1. What are the key characteristics to look for when choosing a dispersant, and how do we choose between two?

  2. What are the ways to prevent sedimentation?

  3. How to avoid getting poor color strength and hiding power?
