Formulation Material Selection

Compatibilizers for Base Paint and Colorant: Optimal Selection and Use

Language: English

Length: 90 min

Recorded on: 17 Mar 15

Package Includes

6 month access to Course Recording, Presentation Slides, Q&A Transcript

Course Description

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.

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

Course Outline

The following sections will be covered during this session:

Introduction

Tinting systems

Colorants

Universal colorants

Base paints

Waterborne systems
Solventborne systems

Color development

Colorant acceptance
Test procedures (rub-up test, wetting test, brush-out test...)
Colorant acceptance shortcomings and practical solutions:
- Poor mechanical stability
- Slow color development
- Strong rub-up and/or weak color development in solvent-based paints
- Floatation: Benard cell formation
- Haze formation, low gloss
