<p>A fast-curing polyurea adhesive is created by microencapsulating one of the two components (diamine or isocyanate) and embedding the microcapsules, or microspheres, in a matrix of the other (isocyanate or diamine). The adhesive may then be applied to the appropriate surface, and curing will commence only when the microspheres are ruptured, such as by bondline pressure, or are thermally degraded, such as by applied heat.</p> |
