Abstract
This invention provides a method for forming a stable aqueous composition including composite particles by admixing TiO2 particles and adsorbing emulsion polymer particles at or below the critical composite ratio to an equilibrated viscosity range of from 200 cps to 4000 cps. Also provided is a method for forming a stable aqueous composition including composite particles by admixing TiO2 particles and adsorbing emulsion polymer particles at a mixing intensity of greater than 2 hp/kgal. A method for providing a coating including composite particles is also included.
