What information does the Tg (glass transition …

The Tg of a resin system defines when a thermoset polymer goes from an amorphous rigid state to a more flexible state. Tg is an abbreviation for Glass Transition Temperature. The most important information that the Tg provides is: What is the nature of the polymer at its service temperature?

What is Tg (Glass Transition Temperature)? - Epoxy | …

Glass Transition Temperature (Tg) is the point at which a material alters state – going from a glass-like rigid solid to a more flexible, rubbery compound. Tg is normally measured on a Differential Scanning Calorimeter (DSC) piece of whizzy equipment.

Figures 3 shows glass transition at 90℃, which indicates that the glass transition temperature shifted to the high temperature side due to curing. Contrary to Figures 2, which shows an endothermic peak at glass transition, Figures 3 shows no such peak. This suggests that there is a difference in thermal hysteresis between the …

Use a glass transition point as a measure of the maximum temperature for adhesion. Pyrolysis temperature of the epoxy resin is from about 250 to about 350°C. Basically, it is impossible, although it may sometimes become more peelable when soaked in a solvent or heated above the glass transition point.
