The utility of using polymercaptans for fast set, room-temperature curing epoxy adhesives (5-minute) is well known. Polymercaptan curatives have desirable green strength development which outpaces several other types of epoxy thermoset adhesives that have at least a 5-minute working time. What is not well documented is how polymercaptan curatives work and are formulated with epoxy. This technical presentation aims to show how understanding in polymercaptan formulation can be used to improve the performance of polymercaptan cured epoxy adhesives.
