Tg - Glass Transition Temperature for Epoxies
... 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 mo ...

The deformation, moreover, may often be viewed as a constant-entropy (isentropic) process, since any such deformation is essentially reversible in the absence of significant elastic attenuation. Since any entropy changes are negligible or poorly characterized, we focus on ...
