  • Aqueous water barrier coatings
    Patent number: 11821143
    Abstract: Described herein is a multi-phase polymer binder including an aqueous polymer dispersion, an optional hydrophobic emulsion, and an optional surfactant. The polymer binder, when dried, provides a water uptake of less than about 5 g/m2/20 min, a seal strength of at least about 200 Newton/meter (N/m) as measured at 25° C. or at 90° C., and sufficient block resistance to impart no substrate damage.
    Type: Grant

  • AQUEOUS RADIATION CURABLE POLYURETHANE COMPOSITIONS
    Publication number: 20110017085
    Abstract: The present invention relates to aqueous radiation-curable compositions comprising from 5 to 95% by weight, relative to the total weight of (A) and (B), of at least one water-dilutable (meth)acrylated urethane (A) containing at least one polyethylene glycol segment and at least one pendant hydrophilic group, and from 5 to 95% by weight, relative to the total weight of (A) and (B), of at least one other (meth)acrylated compound (B) selected from the group of water-dispersible(meth)acrylated polyurethanes (B1), water-dilutable (meth)acrylates (B2) different from the (meth)acrylated urethane (A), and mixtures thereof and their use for making inks and overprint varnishes.
