Course Description

Go a step ahead of theoretical aspects of rheology and predict structural behavior, storage behavior, film formation kinetics… with step-by-step demo of rheological data interpretation.


Let David guide you who has years of experience working on Advanced Rheology (SAOS & LAOS), UV Rheology, kinetics of the film formation process and coating structure prediction by rheology studies.


You’ll be able to know that as per your formulation / application key challenges:

  • What is the right rheological test for you?
  • What info could be extracted?  
  • How can that guide your formulation work & reach the expected level?

David is an R&D Scientist specializing in advanced thermal and rheology characterization of polymers, paints, adhesives, and smart coatings formulations. He has years of experience working on advanced rheology (SAOS & LAOS), DSC, TGA, and DMA characterization, including UV rheology, UV-DSC, Raman DSC, and FTIR-TGA. He has also worked on the evaluation of flame retardants on waterborne systems (intumescent paints), the kinetics of the film formation process, and coating structure prediction by rheology studies. Additionally, he has contributed to marine coatings formulations (antifouling and fouling release) with his experience in biocorrosion.

David was part of European Projects H2020 in Aeronautics – Antimicrobial Coating Formulation and Surface Treatments, coating multilayer system design for EWOD (Electrowetting On Device) technology, and antimicrobial edible coatings for the food industry.

Why should you view this course?

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...).

Who should join this course?

  • Technical Directors, Formulators, Production Directors, QC Managers, Students involved in the characterization of paints and rheology for practical purposes.
