The following sections will be covered during this session:
- Introduction of key concepts
- Understand Hydrogen bonding for better adhesion, solubility, pigment stabilisation...
- 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 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?
