Abstract

Ces compositions, qui ont de bonnes propriétés au point de vue du stockage et qui durcissent rapidement, sont obtenues par mélange de deux types de résines époxy avec des particules de charge et un agent de durcissement. L'une des résines est du type épichlorhydrine-bisphénol A et l'autre résine est une résine épichlorhydrine-bisphénol A modifiée avec une résine novolaque époxy. On obtient des films qui durcissent rapidement en utilisant comme durcisseur un polyéther mixte (aromatique-aliphatique) hydroxylé. Le durcissement est accéléré avec un alkylimidazole. Les compositions selon l'invention sont utiles pour revêtir des supports métalliques, en particulier des extérieurs de tuyaux, dans le cas où il est nécessaire d'avoir un durcissement rapide, une bonne flexibilité et de bonnes propriétés adhésives.
