The present invention relates to a method for producing a flat article comprising a material that contains the products of several reactions. The method comprises the following steps: carrying out a pre-cross-linking of a mixture comprising an epoxydation product of a carboxylic acid ester using at least one cross-linking agent in order to form a mouldable material; moulding the mouldable material in the shape of a flat article; and curing the moulded material in order to produce a flat article, wherein the pre-cross-linking reaction is separate from the curing reaction. This invention also relates to a mouldable material that can be stored and to a flat article that can be obtained from the same.
L'invention concerne un procédé pour produire un article plat comprenant un matériau qui contient des produits de plusieurs réactions. Ce procédé consiste à : effectuer une préréticulation d'un mélange d'un produit d'époxydation d'au moins un ester d'acide carboxylique avec au moins un réticulant pour former une matière moulable ; mouler la matière moulable sous la forme d'un article plat et faire durcir la matière moulée pour obtenir l'article plat, la réaction de préréticulation étant distincte de la réaction de durcissement. L'invention concerne en outre une matière moulable, pouvant être stockée, et un article plat pouvant obtenu à partir de cette dernière.
