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

<div>• Sawtooth and 45°PBT impellers were studied to characterise their blending performance over the turbulent and transitional regimes at two scales of operation.</div><div>• Numerical modelling results under selected conditions could be validated with data.</div><div>• 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.</div>
