The reaction is carried Using the existence of the catalyst at temperatures starting from a hundred and fifty °C and a hundred and eighty °C. studies have shown that there is a correlation amongst epoxy equivalent excess weight (EEW) and the glass changeover temperature (Tg) of the ultimate polymer, indicating that higher EEW corresponds to greater Tg.[32]
This final is considerably the strongest on the 3.[citation needed] In contrast, polyester resins can only bond employing the first two of those, which tremendously lowers their utility as adhesives and in marine repair.
