  • Patent number: 5777071
    Abstract: A water-reducible curing and sealing compound for coating concrete substrates is formed by combining a water-soluble salt of an acrylic polymer resin with an alkanolamine. The resulting compound is low in volatile organic compounds (VOC) and achieves the appearance and performance characteristics of traditional curing and sealing compounds containing petroleum-based solvents. In particular, the compound comprises a polymer resin that comprises three monomers, namely a vinyl aromatic monomer, an ester of acrylic or methacrylic acid, and acrylic or methacrylic acid, in a water-miscible solvent; an alkanolamine; and water.
