  • Method and composition for controlling the viscosity of latex compositions that include fly ash
    Patent number: 7879926
    Abstract: The present invention is a method and composition for controlling the viscosity of latex compositions that include fly ash. The composition is an aqueous dispersion comprising water, at least one polymer latex, from about 50 to about 600 parts by weight fly ash per 100 parts by weight dry polymer, and a viscosity stabilizing composition that preferably comprises at least one borate compound. The method includes adding a viscosity stabilizing composition to an aqueous polymer latex composition that includes fly ash. The viscosity stabilizing composition can be used to produce a stirred viscosity of the aqueous dispersion 7 days after mixing that is less than 30% greater than the viscosity of the aqueous composition immediately after mixing.
