Abstract

L'utilisation d'une formulation contenant une résine pouvant être mise en dispersion dans l'eau permet d'accroître les possibilités d'application de revêtements, et d'améliorer en particulier leur résistance à la formation de cloques. Cette résine comprend le produit de la réaction de copolymérisation de monomères vinyliques obtenus par addition, tels qu'un monomère renfermant un groupe acide, un monomère de N-(alcoxyméthyl)acrylamide ou de N-(alcoxyméthyl)méthacrylamide et au moins un autre monomère vinylique. La réaction a lieu en présence d'un solvant contenant un polyol, les groupes OH de la molécule de polyol présentant une réactivité inégale. Le copolymère peut être mélangé à une résine époxy modifiée avec une amine afin de former une composition de revêtement. Des résultats similaires peuvent être obtenus avec une formulation de revêtement comprenant une résine pouvant être mise en dispersion dans l'eau, ladite résine contenant le produit de la réaction de copolymérisation par addition de monomères vinyliques, tels qu'un monomère renfermant un groupe acide, et au moins un autre monomère vinylique mélangé à une résine modifiée avec une amine. Les groupes acides présents dans le copolymère de vinyle obtenu par addition n'ont été que partiellement neutralisés lors de la mise en dispersion aqueuse. Des résines époxy défonctionnalisées avec une amine, utilisées dans des formulations de revêtements, améliorent la résistance à la formation de voile et de taches si les rapports de réaction entre équivalents groupe époxy et équivalents amine primaire ou ammoniac sont proches de 1:1.
