Physico-chemical aspects of water-based emulsion paints Guifo J. Kayem 2134/34392 https://repository.lboro.ac.uk/articles/thesis/Physico-chemical_aspects_of_water-based_emulsion_paints/9396284 An investigation has been performed with a view to elucidating the factors affecting storage stability and particle flocculation during drying of a water-based emulsion paint, by using a model system of polyvinyl acetate latex and a rutile pigment, where the latex was stabilized with sodium dodecyl sulphate and the pigment with polyphosphate (sodium hexametaphosphate). In particular, the studies have concentrated on the influences of sodium dodecyl sulphate (SDS), and polyphosphate on particle stability and film formation. It has been shown that sodium dodecyl sulphate (SDS) improves the stability of the latex and pigment, while polyphosphate improves pigment stability but reduces latex stability.
