Introduction to Pigment Dispersion and Stabilization

This is a Past Course

Recorded on Sep 11, 2019

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

Jochum Beetsma (Expert Consultant) 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?

Once you understand the underlying science behind the root causes, deciding if you should adjust your ingredients or pigment dispersion process is easy. That’s the key we want to share with you to unlock high performance.

  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, dispersing agent for paint, wetting agents...) by learning about simple tests to predict final performance.

Who should view 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)

Great overview for understanding important elements of pigment. Addressed some of my day to day issues.

Karen L. , from General Motors

Excellent discussion of basic dispersion physics/chemistry.

Tayo Y. , from Hewlett-Packard

It was a nice, short compendium about the most critical parameters for good pigment dispersion... Great time saving vs. digging through textbooks!

Sandra H. , from Dow

Very good background information on the fundamentals of pigment (and particle) dispersion

Neil B. , from Hewlett Packard

I do not come with a background in paint but could clearly understand the difference between dispersion and wetting and feel that now I can actually explain why our products work better than the competition.

Rajesh I. , from DIC India Ltd.

The pigment wetting & penetration process was really well explained.

Joel R. , from Folien Fischer AG

A very nice summary of the aspects required to be considered when optimising dispersion.

Stewart W. , from Silberline Ltd.

An Excellent Course! Pigment dispersion is the most demanding and most important part of a paint and/or ink formulation and this course covers it well.

Monika A. , from Franz Barta GmbH

great expanation of surface tension and surface energy and how it relates to penetration, wetting...
