Applicable Base Polymer Properties
Epoxy adhesives are generally more resistant to a wide variety of liquid environments than other structural adhesives. However, they are generally considered to be very rigid systems, and as such they do not have exceptionally good impact or peel resistance unless modified with tougheners.
DuoMod® 5045 is pre-crosslinked and carboxyl functional ultra fine NBR powder designed specifically for the modification of epoxy based resins. It provides large increases in fracture toughness when compared with unmodified formulations. DuoMod has been found to overcome many of the shortcomings of conventional epoxy tougheners at loading levels less than 4%.
