  • Reactive hot melt adhesive with improved hydrolysis resistance
    Patent number: 8664330
    Abstract: High green strength reactive hot melt adhesives are prepared using relatively low levels of reactive acrylic, and may be prepared with liquid crystalline or crystalline diols.
    Type: Grant
    Filed: April 4, 2003
    Date of Patent: March 4, 2014

  • High heat resistant adhesive and sealant compositions
    Patent number: 8349123
    Abstract: The invention provides adhesive and sealant compositions prepared from urethane prepolymers. The urethane prepolymers are obtained by reacting the novel urethane diols, polyester polyols and polyether polyols with an excess of diisocyanate. The urethane diols are prepared by reacting excess low molecular weight diols and diisocyanates. The invention is particularly useful in end use applications such as panel lamination.
