  • Publication number: 20210198498
    Abstract: The present invention provides an anti-corrosion composition comprising an organic ion-exchanger; and a waterborne resin, wherein a substrate exposed to a halide-containing environment and having the anti-corrosion composition applied thereto has a reduced level of corrosion compared to the substrate exposed to the halide-containing environment without the anti-corrosion composition being applied. The inventive waterborne anti-corrosion composition may find use on substrates such as automotive vehicles, bridges, cranes, superstructures, offshore oil & gas rigs, pipes, tanks, ships, barges, boats, aircraft, concrete, and masonry that are exposed to halide-containing environments.

  • Publication number: 20210122873
    Abstract: The present invention provides an aqueous polyurethane dispersion (PUD) which comprises (1) a polyester polyurethane dispersion which is free of solubilizing agents having carboxyl functionality and (2) a polycarbodiimide dispersion. These dispersions have stabilized performance properties. In addition, the polycarbodiimide dispersion has been found to restore the physical performance of an aqueous polyester polyurethane dispersion in which the performance has degraded due to the polyester component.

  • Publication number: 20200247940
    Abstract: The present invention provides a stable, one-component polyurethane dispersion (PUD) based on ortho-phthalic based polyester polyols with a range of molecular weights. The stability is achieved by addition of from greater than about 1% to about 5% of a polycarbodiimide to the PUD. This chemistry provides coatings, adhesives, sealants, paints, primers, topcoats, and composites having excellent chemical resistance, especially with regard to aggressive detergent testing. The instant invention provides two-component performance with a one-component coating. The addition of a polycarbodiimide dispersion stabilizes a number of performance properties of the PUD over time such as, adhesion, detergent resistance, window cleaner resistance, 70% isopropyl alcohol resistance, pencil hardness, impact resistance, viscosity, pH, acid value, and pot life.
