Rheology Modifiers: Optimal Selection & Use

On-Demand Course

Recorded on Jun 18, 2014

Take control on stability, sag resistance, leveling… by optimizing rheology modifiers selection & loading, especially with latest associative technologies (polyurethane, hectorite organo clays…)

Johan Bieleman will explain how to best suit your new system constraints (low VOC, high shear…) while avoiding unwanted interactions with other paints ingredients (colorants, surfactants…)

Why should you view this course?

Controling the rheological properties plays a dominant role during the production, storage, application and curing of paints and inks. But too often, formulators struggle selecting the right rheology modifier for better stability, sag resistance, spray- and brush-ability, opacity... while avoiding unwanted interactions (with colorants, surfactants...) !

  1. Save time selecting rheology modifiers with an organized set of selection criteria (rheology profile, cost, physical properties…)
  2. Achieve faster targeted stability, flow… by understanding how they are impacted by your rheology modifiers selection & use
  3. Optimize thickeners efficiency (the right loading at the right time, no unwanted interaction) with tips learnt over 40 years in the field
