Register
Greg Percival, Resene R & D Senior Chemist, will be presenting a technical talk on Rheology of Paint Applications.

This talk is also the first technical talk we are going to run as a hybrid event.  We ask you for your patience as this is the first time we are doing this, and while we have a good idea of what we are doing, who knows what will happen on the night.

Abstract:

This presentation will introduce the science of rheology with respect to the relationship between paint viscosity at various shear rates during manufacture, storage and application. Resistance to flow is dominated by chemical interactions at low shear rates which are replaced by physical interactions at high shear rates. Techniques to relate viscosity measurements with application properties will be discussed along with experiments to quantify the forces involved with brushing and roller application.

Bio:

Greg has been dabbling in paint chemistry and the mechanics of paint application since 1978, firstly with solvent-based aerosol and industrial coatings, then later with water-based technology.

Greg received a NZCS (Chem) in 1980 and a Diploma in Surface Coatings Technology in 1983 from the Auckland Technical Institute. While working for Rohm and Haas Company, he received an Otto Haas Technical Excellence Award in 1997 for work in computer modelling & simulation of paint formulating.  Greg visited paint companies in over 20 countries supporting Rohm and Haas technically and has presented papers in New Zealand, Australia, China and Singapore.

Greg joined the Resene technical team in 2008 and is based at the Resene Automotive & Light Industrial offices in Mt. Wellington, Auckland, working on Automotive, Construction and Architectural products.

He is currently the President of the New Zealand Paint Manufacturers Association, and is a well respected member of the World Coatings Council.

Greg and his family reside in the North Waikato, where he shares his time evenly between family, Resene Paints and motorcycle racing.
