  • Low-VOC aqueous coating compositions with excellent freeze-thaw stability
    Patent number: 7612126
    Abstract: The present invention relates to an aqueous coating composition having excellent freeze-thaw stability and a low-VOC content, comprising a multi-stage polymer dispersion comprising (a) an inner phase comprising at least one latex polymer derived from at least one monomer and at least one polymerizable alkoxylated surfactant having the structure: R1—R2 wherein R1 is an allyl group selected from the group consisting of CH3—CH?CH— and CH2?CH—CH2—, or an acrylic group and R2 is a radical comprising at least two carbon atoms and at least one oxyethylene or oxypropylene unit; (b) an outer phase having a glass transition temperature of from 30° C. to 110° C. containing at least one ethylenic unsaturated monomer (c) at least one pigment; (d) water; and (e) less than 3.0% by weight based on the total weight of the aqueous coating composition of anti-freeze agents.
    Type: Grant
    Filed: December 1, 2004
    Date of Patent: November 3, 2009
    Assignee: BASF Aktiengesellschaft
    Inventors: Konrad Roschmann, Joerg Leuninger, Rolf Dersch, Cheng-Le Zhao, Li Zhuo, Terri A. Cunningham
