Abstract

L'invention concerne une composition à composants multiples, comprenant : A) un composant liant (A) comprenant au moins une résine époxyde ; B) un composant durcisseur aqueux (B) comprenant au moins un composé amine comme durcisseur amine et de l'eau ; et C) un composant solide (C) comprenant au moins un liant inorganique hydraulique, de préférence un ciment. La composition à composants multiples contient par rapport au poids total, au moins 8 % en poids de liant organique, la quantité totale de résine époxyde et de durcisseur amine constituant le liant organique. La composition à composants multiples contient de préférence au moins un pigment comme colorant. La composition à composants multiples est remarquablement appropriée pour la production de revêtements ou de scellements de sol, qui peuvent être fabriqués en une grande diversité de coloris.
