Webimpact, toughened applications. Introduced in the early 1990’s, reactive urethanes are a new, hybrid chemistry. These adhesives are the only thermosetting hot melt adhesives that combine the advantages of traditional thermoplastic technology with the high performance characteristics of reactive adhesive chemistries (Figure 1). WebAmbient reactive extrusion ARE is a form of MatEx in which a thermosetting resin is extruded under ambient conditions. The curing agent is mixed into the thermosetting resin immediately before extrusion, which facilitates the flow of the extrudate, followed by rapid curing after the bead is printed.
