  • Publication number: 20070055002
    Abstract: A water-borne latex paint system, comprising a base paint, an associative thickener, a colorant compound, and at least 0.1% dry weight of a block copolymer ABCBA composition. For the ABCBA polymer wherein the A component is a hydrophobic group A, the B component is a hydrophilic polymer B and the C component is a low molecular weight hydrophobic group C. The ABCBA-type polymer includes an A component which is a monomer unit containing a moiety selected from the group consisting of an alkyl group, an aryl group or an alkyl aryl group, the B component includes poly(ethylene glycol), and the C component is selected from the group of diols consisting of poly(tetrahydrofuran), poly(caprolactone) poly(carbonate), ethylene glycol, propylene glycol, and 1,2-dodecanediol. The block copolymer acts as a viscosity stabilizer in the presence of associative thickeners.
