  • Liquid coloring suspension and colored cementitious composition
    Patent number: 7497904
    Abstract: A cementitious composition is provided that is composed of hydraulic cement and a liquid coloring suspension. The liquid coloring suspension which contains polycarboxylate dispersant and pigment provides the cementitious composition with increased dispersion of pigment particles, lowered water content, and improved coloration over that observed in the prior art. Also, a liquid coloring suspension for cementitious compositions is provided which contains polycarboxylate dispersant, pigment, and thixotropic additive. The liquid coloring suspension increases the color of cementitious compositions, reduces the water content and has long term stability in that it does not become increasingly viscous over time.
    Type: Grant
