Course Description

You can solve all your coatings formulation challenges (stabilization, dispersion, film-defects…) much faster than you think, when you understand the physical chemistry behind the root causes of the issues!

Join top coatings consultant Jochum Beetsma in this simulated live. He will guide you on:

  • The chemistry behind each process & concept (surface tension, adsorption, wetting, colloidal stability, capillary phenomena, coalescence...)
  • Insights on how to identify solutions

Why should you view this course?

Most of the challenges (stabilization, dispersion, film defects…) in coatings are due to the lack of understanding of physico-chemical concepts.
And, it appears that if these concepts are known and understood, they can be used to tackle those challenges systematically. So, why wait? Join the course and:

  1. Increase your ability to analyze how ingredients interact in your formulation and optimize the cost/performance ratio of coatings.

  2. Understand clearly the physical chemistry behind each process & concept (adsorption, wetting, adhesion, capillary pressure, wetting…) to make better decisions in your day-to-day work.

  3. Better link your formulation issues with their root causes (surface tension, rheology…) to find accurate solutions and save time on trial & error.

Who should join this course?

  • Developers of raw materials, Coatings and Inks formulators, & producers with a need to get an in-depth understanding of physico-chemical coatings concepts must opt for this course.

Course Outline

The following sections will be covered during this session:

Introduction of key concepts

Understand Hydrogen bonding for better adhesion, solubility, pigment stabilization...

Surface tension and surface energy

Adsorption of materials at interfaces

Wetting: a pre-condition for good adhesion and wetting agents

Capillary phenomena caused by curved interfaces & how it helps in pigment wetting

Coalescence of binder dispersions

Osmosis

Colloidal stability: electrostatic and steric repulsion

30 mins Q&A: ask your questions directly to the expert!

Here are the kinds 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 stabilization often fail in water-based 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 transition temperature?
