Simplifying Physical Chemistry for Faster Problem Solving

This is a Past Course

Recorded on Apr 11, 2019

Troubleshoot faster your day-to-day problems (stabilization, dispersion, film-defects…) by knowing the underlying physical-chemistry principles (surface tension, adsorption, wetting, colloidal stability, capillary phenomena, coalescence...).

Jochum Beetsma will guide you in the identification of the root causes and the associated solving strategies (no more unfocused trials!)

Why should you view this course?

With all the components in a coating system what a pain to solve formulation issues with unfocused trials! Let us explain the physico-chemical phenomena that will help you identify the root causes faster. Join the course and:

  1. Save time solving issues by quickly linking poor performance to physico-chemical root causes

  2. Deal efficiently with adsorption, wetting, adhesion, capillary pressure, pigment wetting, and stability issues

  3. Increase your ability to analyze how ingredients interact in your formulation and optimize cost / performance ratio of coatings & inks
Physical Chemistry for a Good Start in Problem Solving (Part 1)

Who should view this course?

Developers of raw materials, Coatings and inks formulators, & producers with a need to troubleshoot day-to-day issues faster with less unfocussed trials! Join this course and get more familiar with underlying physico-chemical principles for faster problem solving.

Course Outline

The following sections will be covered during this session:

  1. Introduction of key concepts
  2. Understand Hydrogen bonding for better adhesion, solubility, pigment stabilisation...
  3. Surface tension and surface energy
  4. Adsorption of materials at interfaces
  5. Wetting: a pre-condition for good adhesion and wetting agents
  6. Capillary phenomena caused by curved interfaces & how it helps in pigment wetting
  7. Coalescence of binder dispersions
  8. Osmosis
  9. Colloidal stability: electrostatic and steric repulsion
  10. 30 mins Q&A: ask your questions directly to the expert !

Here is the kind of questions you will be able to answer without difficulties:

  • How does capillary pressure help in both pigment wetting and film formation?
  • Why does electrostatic stabilisation often fail in waterbased systems?
  • What does surface tension really tell and how can the property be used?
  • How can I predict whether or not a wetting agent will be needed?
  • How can I quickly check pigment hydrophilicity / hydrophobicity?
  • How is it possible that a binder dispersion forms a film below the glass trasnsition temperature?

Very good fundamental approach to coating formulation and stabilization

Ben G. , from Andersen

Excellent physical examples of the mechanisms of surface energy helping to describe the equations.

Michael D. , from Taconic

Excellent! It applies directly to our coatings work and discusses helpful problem solving techniques.

Tim P. , from Sawgrass Technologies

Excellent - Condensed math concepts to allow relevance to operations used in everyday work.

Roger K. , from Eastman Kodak Company

Understanding the forces behind the dispersion of pigments and film formation can provide insight into diagnosing and resolving formulation issues. This course gave me a boost!

Tiffany S. , from The Sherwin Williams Company

An Excellent Course! I now understand why I've had trouble coating certain substrates with my PSAs.

Herbert C. , from Cray Valley USA

Improved my understanding of the underlying causes of many formulation and film defects we often observe during development. This course gave me the tools that may help combat them.
