Abstract

The structural changes of polyamino-amide and polyamino-imidazoline, used as curing agents for water-based epoxy materials (WBEM), have been examined under various conditions of storage. Additionally, epoxy emulsion stabilization and film-forming in WBEM needed special research to set the limits of material utility. Infrared analysis, potentiometric titration and viscometric data obtained for some curing agents for WBEM, commercial polyamino-amide and the derived polyamino-imidazoline compounds, prove that during prolonged storage (from 1 to 140 days) these products can hydrolyse to yield free amines and carboxyl groups. The reaction mechanisms are suggested. The results include considerations for further development of epoxy compositions and a study of film-forming properties.

Résumé

On a examiné, dans différentes conditions de stockage, les modifications de structure des polyamino-amides et de polyamino-imidazolines, d'agents de cure et des émulsions eau/époxydes (WBEM). La stabilisation de l'émulsion epoxyde et les propriétés filmogènes des WBEM exigent de surcroît des recherches particulières pour définir les limites d'utilisation du matériau.

L'analyse infrarouge, le titrage potentiométrique et les données viscométriques obtenues pour les polyamides commerciaux et les composés polyaminiimidazolines ainsi que pour certains agents de cure utilisés pour les WBEM montrent que, au cours d'un stockage prolongé (1 à 140 jours), ces produits peuvent subir une hydrolyse qui libère les amines libres et les groupes carboxyles. Les mécanismes de ráction ont donné lieu à des hypothèses. On a pris en considération les résultats pour un développement ultérieur des composés époxydes et l'étude des propriétés filmogènes.
