| Résumé : |
The influence of the glass transition temperature and the mechanical and anticorrosion properties of factors such as the amount of plasticizer added to an epoxy primer were investigated by DSC (differential scanning calorimeter), DMA (dynamic mechanical analysis), stress-strain tests, salt fog spray tests, accelerated tests, and electrochemical tests. The addition of plasticizer results in a decrease in the glass transition temperature and a change in the mechanical properties. Different tests were carried out to the optimum percentage of plasticizer content (1.5-3% weight ratio to epoxy resin) required to obtain the maximum anticorrosion performance of the epoxy primer. These changes are explained by the structural-kinetic effect exerted by the plasticizer on the chemical crosslinking in the course of the epoxy network synthesis and the increase in the excess free volume. |
