The rheological properties, gloss, hiding power, and water absorption
of some model latex paints were analyzed in terms of the adsorption of
surfactants, dispersing agent, and thickener onto the latex and pigme
nt particles. Special attention was paid to the order of addition of p
oly(acrylic acid) and ethyl(hydroxyethyl) cellulose, because this has
an effect on the adsorption of the polymers onto the TiO2 pigment. The
order of addition also affects the rheological properties of the mill
base dispersion and the gloss of the paint. The gloss was also affect
ed by the surfactant used to stabilize the latex. Higher gloss was obt
ained using a nonionic surfactant than with an anionic surfactant.
