Compatibilizers for Base Paint and Colorant: Optimal Selection and Use

On-Demand Course

Recorded on Mar 17, 2015

Reach faster uniform and optimal color development by reviewing parameters to consider when matching your compatibilizers (Nuosperse 2006, Pat-Add DA 301, EFKA 6225…) with your base paint & colorants for optimal performance and quality.

Expert Johan Bieleman will share a proven additive selection procedure and explain the effect of viscosity, hydrophobic/ hydrophilic ratio, extenders… on compatibility & stability.

Why should you view this course?

Stringent regulation on APEO surfactants, organic solvents, VOC… is making compatibilizers more needed than ever when formulating paints & inks. Today formulators, by lack of self-understanding of interactions occurring in their tinting system, either rely on their colorant suppliers’ suggestions or waste their precious time with trial-and-errors to come up to a satisfying formulation.

  1. Save your time and effort by adopting a systematic approach to choose a compatibilizer based on the chemistry of your based paint and colorant.
  2. Troubleshoot faster issues (lack of reproducibility or color uniformity, color instability, rub-up, lower VOC…) by knowing their root causes & best solving strategies
  3. Get advice on your own technical challenges by interacting live with a season formulator ( >40 year experience)

Very good course, which I can apply in some issues.


The course focused on practical problems and suggestions.
