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. [Continues.]
