Process for bonding two substrates together with a one-part moisture curable polyurethane adhesive

A process for binding two substrates together which comprises contacting a one-part adhesive composition with at least one of the substrates and contacting the substrates together along the portion of the substrate(s) to which the adhesive composition has been applied before the adhesive composition applied cures and allowing the adhesive composition to cure and bond the substrates together wherein the one-part adhesive composition comprises a polyurethane prepolymer comprising the reaction product of;

• A) one or more polyisocyanates;
• B) a mixture of one or more polyether diols and one or more polyether triols;
• C) a dispersion triol containing from about 10 to about 60 percent by weight based on the dispersion of organic polymer particles having a particle size of from about 10 to about 50 microns and which are not reactive with isocyanate or isocyanate-reactive moieties wherein the organic polymer is derived from styrene, halo or alkyl substituted styrene;
• or a rubber modified polymer derived from styrene, or halo or alkyl substituted styrene;
• and a catalyst comprising the mixture of a dimorpholino diethyl ether or a alkyl substituted dimorpholino diethyl ether and a bismuth carboxylate;
• wherein the prepolymer has a free isocyanate content of from about 0.8 to about 2.2 percent.
