    摘要: The invention is an adhesive composition comprising: a) an isocyanate functional polyether base prepolymers having a z molecular weight average (Mz) of about 10,000 to about 80,000 g/mole; a carbon black having an average oil absorption number of at least about 80 to at most about 400 cubic centimeters of dibutyl phthalate per 100 grams of the carbon black; (c) reactive silicon in an amount from about 0.001% to about 10% by weight of the adhesive composition; and (d) one or more catalysts for the reaction of isocyanate with hydroxyl groups. The adhesive compositions of the invention surprisingly may have improved sag performance (i.e., decreased sag) when heated, while also making them more easily pumped.
