  • Bookbinding process
    Patent number: 8333542
    Abstract: A curable hot melt adhesive is used as a primer on a book block. A conventional thermoplastic hot melt is then applied on top of the reactive hot melt before the cover material is positioned.
    Type: Grant
    Filed: October 24, 2001
    Date of Patent: December 18, 2012
    Assignee: Henkel AG & Co. KGaA
    Inventors: Dave G. Carter, Malcolm Graham, Kim Tagesen
  • Reactive hot melt adhesive
    Patent number: 8277601
    Abstract: Solvent free, moisture curable reactive hot melt adhesives are prepared using an oxazolidine functional prepolymer and a polyfunctional isocyanate.
    Type: Grant
    Filed: December 12, 2008
    Date of Patent: October 2, 2012
    Assignee: Henkel Corporation
    Inventors: Andrew Slark, Malcolm Graham

  • High green strength reactive hot melt by a prepolymerization in the main reactor
    Patent number: 6365700
    Abstract: It has been found, in accordance with the present invention, that a high molecular weight polyester, when reacted with a poly or diisocyanate in an NCO:OH ratio of 0.7:1 to 1:0.7, produces a high molecular weight hydroxy terminated prepolymer which is stirrable above 120° C. and sufficiently stable prior to reaction with additional di or polyisocyanate or optional additional polyols to produce a reactive hot melt adhesive.
    Type: Grant
    Filed: June 7, 1999
    Date of Patent: April 2, 2002
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventor: Malcolm Graham
  • Catalyst for reactive hot melt adhesives
    Patent number: 5550191
    Abstract: A catalyzed polyurethane reactive hot melt adhesive is prepared from a reactive polyurethane prepolymer and 0.05 to 0.6% by weight of a 2,2'dimorpholinoethyl ether or di(2,6-dimethylmorpholinoethyl)ether catalyst. The adhesive is characterized by improved curing speed with little or no effect on the thermal stability.
    Type: Grant
    Filed: April 25, 1995
    Date of Patent: August 27, 1996
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventors: Ju M. Hung, Malcolm Graham
  • Single pack polyurethane adhesive
    Patent number: 5110892
    Abstract: Stirrable reactive polyurethane adhesive compositions are packaged in a single container by separating the reactive components with a disperable barrier layer so as to delay reaction until the entire adhesive composition is stirred together.
    Type: Grant
    Filed: December 18, 1990
    Date of Patent: May 5, 1992
