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.
