Epoxy adhesives five-minute

Capcure 3-800 LC (9) is a very useful material with polyether in the backbone and with three beta hydroxy mercapto end groups. Amine catalysts are usually added to control the work life increasing the concentration of amine leads to a shorter work life. These are the Five Minute Epoxies familiar to the home user. After cure these adhesives tend to be brittle peel strengths are only two to five pounds with catastrophic failure over the length of the bond. 

The reaction is similar to that found with hydroxyl groups and produces a polythioether product. These are the familiar five-minute epoxy adhesives and have the characteristic odor of thiols.
