Mixing studies relating to process development for new generation automotive coating formulations

• Sawtooth and 45°PBT impellers were studied to characterise their blending performance over the turbulent and transitional regimes at two scales of operation.

• Numerical modelling results under selected conditions could be validated with data.

• Experiments performed using liquids that simulate the physical properties of coating formulations have led to the development of a process for the manufacture of high performance automotive coatings.
