Understanding Physical Chemistry of Paints and Coatings

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 to wait? Join the course and:

1. Increase your ability to analyze how ingredients interact in your formulation and optimize 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 solution and save spending your precious time on trial & error.

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

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?
