  • Primerless urethane adhesive compositions
    Patent number: 5606003
    Abstract: A two-component urethane adhesive is disclosed which requires no primer or pretreatment of the substrate. The adhesive in cured form has superior paint adhesion and can withstand high temperature bake cycles without substantial losses in adhesion to the substrate. The adhesive differs from prior adhesives in that essentially all of the high molecular weight polyols in the prepolymer component are the reaction product grafting reactions of acrylonitrile onto polypropylene polyols.
    Type: Grant

  • Adhesive composition
    Patent number: 5508111
    Abstract: A polyurethane adhesive formed from (I) an NCO terminated prepolymer with excess of NCO and talc, and (II) a polyol, a urethane catalyst, talc and a minor amount of certain aryl or aromatic polyamines exhibits good sag and thixotropic properties and, also, exhibits good lap shear strength when cured between treatment-free substrates.

  • Thermoplastic polyurethane prepared from a poly-1,2-propylene ether glycol, a low molecular weight glycol and 2,4-tolylene diisocyanate
    Patent number: 4239879
    Abstract: A thermoplastic, linear and segmented poly-1,2-propylene ether urethane having a Tg of below about -30.degree. C. for the poly-1,2-propylene ether segments is made by reacting poly-1,2-propylene glycol having a high molecular weight; ethylene glycol, 2,3-butane diol or neopentyl glycol or mixture thereof; and 2,4-tolylene diisocyanate containing from about 55 to 100% by weight of the 2,4-isomer with the balance being the 2,6-isomer.
