The basic relationship Modulus has to adhesives is: the higher the Tg, the higher the cross-linked density and the higher the modulus. As
an epoxy rises above its Tg, the storage modulus drops. This is indicative of the change from a rigid to compliant state.
A high Tg along with a high storage modulus, results in a high stiffness which in most cases equates to a low percent elongation and poor
energy dissipation when stressed at ambient temperatures. The modulus below the Tg has a primarily linear inverse relationship with
temperature.
