Pigments & Fillers Selection for Optimal Performance & Cost

Pigments & fillers play a key role in paints and inks. It goes far beyond color for pigments and cost for fillers… They can help improve key film properties (adhesion, barrier properties, flexibility, mechanical strength, sandability, scratch resistance…) and lower VOCs.

1. Predict the effect of pigments & fillers on your formulations by simply using their characteristics described in TDS (shape, hardness, critical PVC, oil adsorption…)
2. Reduce system costs, lower VOC, improve adhesion... by exploiting pigments & fillers at their full potential in your coatings & inks
3. Troubleshoot faster by having sufficient knowledge on your materials to understand what is happening & how to fix it

Principles and phenomena, being associated with production, stability, application and lifetime of coatings and inks will be discussed in this online course. Jochum Beetsma will tackle typical behaviour of liquid systems like dispersion, stability and rheology. We will see how solid raw materials, being pigments and fillers, influence virtually all system properties.

Summary of the topics as included in the e-Training Course:

• Properties of liquid systems: rheology, solids content, VOC, colloidal stability, sedimentation and wear of equipment.



• Properties of films: adhesion, flexibility, permeability, corrosion resistance, hardness, abrasion resistance, sandability, chemical resistance, hiding power and colour strength.



• Key properties of solid raw materials: particle size, particle shape, specific surface area, oil adsorption value, Critical Pigment Volume Concentration, Moh hardness, surface composition, post-treatment, pH, density and fastness.



• Link between properties of solid raw materials and properties of complete systems and films resulting from those systems.
