Abstract: A pigment grind dispersion of titanium dioxide pigment-polymer composite particles is made by mixing titanium dioxide particles with an aqueous emulsion containing (i) less than a saturation level amount of water-insoluble film-forming first polymer particles that adsorb to the titanium dioxide particles, and (ii) an inhibiting or interfering amount of water-insoluble film-forming second polymer particles that do not adsorb to the titanium dioxide particles, wherein the pigment grind dispersion has a titanium dioxide pigment volume concentration of about 25 to about 50 and a titania composite ratio of about 32 to about 60. The resulting titanium dioxide pigment-polymer composite particles can provide improved coating composition opacity compared to a coating composition that does not contain such composite particles, can employ reduced titanium dioxide amounts and less than a saturation level of the first polymer, and can provide improved storage stability.

Abstract: A paint brush and method include a ferrule extending around and in contact with a plurality of bristles and a spacer apparatus positioned to space apart the plurality of bristles to provide at least one reservoir within the plurality of bristles. The spacer apparatus defines at least one opening extending through the spacer apparatus that allows fluid passage therethrough to the at least one reservoir to assist in removal of paint from the plurality of bristles when fluid is provided therein.

Abstract: A coating composition including a rheology modifier is described. The rheology modifier is a water-soluble polyurethane made by the condensation of a poly(alkylene glycol), a polyisocyanate and a compound including a polyalkoxylated chain and a hydrophobic end group. The composition demonstrates Leneta sag resistance of greater than about 14 and a Leneta flow and leveling of at least about 9, and a Stormer viscosity of less than about 120 Krebs units.
