| abstract |
The invention is the process for binding two substrates together using a two-part adhesive comprising as a first part: A. a polyurethane prepolymer having reactive isocyanate moieties; and a second part B. a curative composition comprising i) a polyurea, comprising the reaction product of a polyamine and a polyisocyanate, dispersed in a polyether polyol-based polyurethane prepolymer having reactive hydroxyl moieties, and optionally a plasticizer; ii) a compound having at least one oxazolidine moiety capable of reacting with an isocyanate under curing conditions; and iii) a catalyst capable of catalyzing the reaction of isocyanate and hydroxyl moieties in the presence of moisture. |
