  • Adhesive composition comprising a particulate thermoplastic component
    Patent number: 6548579
    Abstract: The invention is directed to an adhesive composition comprising a water based component including a film-forming polymer and a particulate thermoplastic component selected from the group consisting of thermoplastic polymers, thermoplastic resins, hot melt adhesive compositions, and mixtures thereof. The thermoplastic component has a mean particle size of from about 10 microns to about 1,500 microns. The adhesive composition is useful as a one-shot bookbinding adhesive, a primer composition as well as a second-shot adhesive for two-shot bookbinding method. The invention is also directed to the bookbinding methods using the adhesive composition.
    Type: Grant

  • Stable aqueous polyurethane dispersions
    Patent number: 6017998
    Abstract: The present invention discloses a stable aqueous polyurethane dispersions comprising a reaction product of a water dispersible isocyanate-terminated polyurethane prepolymer (A), an aqueous polyurethane dispersion (B) and water, and a method wherein a water dispersible isocyanate-terminated polyurethane prepolymer (A) is dispersed in at least one aqueous polyurethane dispersion (B) and water, and reacted at about 35.degree. C. to about 95.degree. C. until substantially free of isocyanate. The inventive dispersions are useful in adhesives, coatings, binders, primers and sizers.
