Introduction to Pigment Dispersion & Stabilization- Part 1

This is a Past Course

Recorded on Mar 2, 2017

Gain in speed & efficiency when you troubleshoot poor pigment dispersion cases (color strength, hiding power, paint stability, conductivity, corrosion resistance…)

Jochum Beetsma will give you a practical tour into the underlying science (dispersion mechanisms and factors influencing it) so you can better identify your problem root causes and opt for the right solution.

Why should you view this course?

Once you understand the underlying science behind the root causes, deciding if you should adjust your ingredients or dispersing process is easy. That’s the key we want to share with you to unlock your performance. Join this course and:

  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 1

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.)

Course Outline

The following topics will we discussed during this 2-part introduction formulation course on pigment dispersion:

PART 1: Mar 2, 2017

1. Introduction
2. Pigment wetting (surface tension -
surface energy)
3. Penetration (capillary flow)
4. Hold-out
5. Wetting agents
6. Particle separation
7. Dispersion equipment (partial)

Case studies to work on (answers provided in Part 2):
- Wetting agents in waterbased paint
- Coating of plastics
- Hydrophobic pigments in water
- Dispersant for ironoxide pigment
- Alkyd resin as dispersant

PART 2: Mar 16, 2017

1. Summary of Part 1
2. Dispersion equipment (continued)
3. Pigment stabilisation
4. Dispersants
5. Stability problems
6. Conclusion

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

Neil B. , from Hewlett Packard

Excellent discussion of basic dispersion physics/chemistry.

Tayo Y. , from Hewlett-Packard

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

Michelle S. , from Imagine Crafts

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

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

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

Stewart W. , from Silberline Ltd.

The pigment wetting & penetration process was really well explained.

Joel R. , from Folien Fischer AG

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