ABSTRACT:
A 100% solids polyurethane adhesive composition for bonding polymeric roofing materials to roof-deck substrates is provided which includes two components. The first component comprises a monomeric or polymeric diisocyanate, or a polyurethane prepolymer formed by the reaction of the monomeric or polymeric diisocyanate with a polyol. The second component comprises a polyol selected from the group consisting of a polyether or polyester polyol, an alkanolamine diol, a hydroxyl-terminated homopolymer of polybutadiene, and mixtures thereof. The first and second components are combined such that the ratio of isocyanate groups in the first component to the ratio of hydroxyl groups in the second component is from about 0.5:1 to 1.5:1.
