MoreMALVERN, UK - Adrian Hill, Rheology Product Technical Specialist at Malvern Instruments, will discuss the importance of understanding the links between rheology and particle parameters when he speaks at the forthcoming PRA Measurement & Testing of Coatings Conference on May 12-13, 2009, Birmingham, UK.
Hill’s presentation will examine how the rheology of a suspension is influenced by particle size, particle size distribution and the volume fraction of solids present and the way in which zeta potential, a measure of the electrostatic interaction between particles, also has a marked effect.
Armed with this understanding, it is possible to manipulate specific variables in order to produce coatings materials with the required rheological properties for robust and optimized application performance. Examples from the coatings industry will illustrate the practical benefits of both rheological measurements and particle characterization.
