  • Aqueous Dispersions Of Polyurethane/Acrylic Hybrid Compositions
    Publication number: 20090137734
    Abstract: An aqueous dispersion of polyurethane/acrylic polymer hybrid composites is made by forming a mixture of urethane prepolymer or polymer, acrylic monomer or polymer, ketone functional molecule/oligomers, and hydrazine functional molecule/oligomers; and dispersing the mixture so made in aqueous medium.
    Type: Application
    Filed: January 12, 2009

  • AQUEOUS POLYURETHANE COMPOSITIONS FOR LOW GLOSS COATINGS
    Publication number: 20090012226
    Abstract: An aqueous coating composition having a 60° gloss of ?40 upon drying comprising a self-crosslinkable polyurethane obtained by the reaction of: (A) an isocyanate-terminated pre-polymer formed from components which comprise (i) 5 to 65 wt % of at least one organic polyisocyanate; (ii) 0.

  • Aqueous Dispersions Of Polyurethane Compositions With Ketone-Hydrazide
    Publication number: 20080027168
    Abstract: An aqueous dispersion of polyurethane composites is made by forming a dispersion of urethane prepolymer or polymer and ketone functional molecule by dispersing them in an aqueous media and adding a hydrazine functional molecule. When the ketone functional molecule is derived from levulinic acid and epoxidized vegetable oil, the resulting urethane dispersion has enhanced coalescence with less need for coalescing aids.
