Basque Country -- Chemical engineer Ms InÃªs Mariz has presented guidelines for obtaining better quality and more efficient latex, in a PhD thesis defended at the University of the Basque Country (UPV/EHU). The thesis is entitled High solids content low viscosity latexes with small particle size. A number of articles have also been published based on the research, including one in Polymer Journal.
Ms Mariz worked for some time in the paints division of AkzoNobel and said the objective of this thesis was to set out a strategy for producing latex with high solid content and low viscosity, but with particles of a size less than 350 nanometres, so that a film of the latex could dry quickly with a good surface finish. .
The result was a bimodal latex which, with particle sizes less than 350 nanometres, has high solid content (up to 70 wt%) and the lowest possible viscosity.
