Applied Rheology for Improved Performance in Paints and Coatings

A lot of cost of a new product development goes into ‘getting the rheology right’. Even minor changes in a raw material can cause significant variability in product rheology. Moreover, environmentally compliant coatings have resulted in more complex rheology while reducing the number of formulating options and at the same time generating a host of performance/application problems. 

Let David help you launch your products faster in the market by reaching the desired performance level with much needed practical rheological guidance to drive your formulation work. Join this course to:

1. Understand the difference between the rheology characterization in flow (process behavior), & in oscillation (prediction of structural behavior-storage behavior-film formation process & kinetics parameters in the film formation process)
2. Efficiently predict your coatings formulations’ behavior by knowing intramolecular interaction in a formulation that will later be exposed to environmental conditions of a given market.
3. Enhance your interpretation skill of the different types of tests in the characterization with real-life examples (Alkyd Enamel characterization, Comparison of Two Spanish paints…)
