Abstract

Résines destinées au contact des aliments La présente invention concerne une résine destinée au contact des aliments comprenant de 0,05 à 0,5% en poids de graphène par rapport au poids total de la résine. Elle concerne de plus son utilisation pour le revêtement intérieur de réservoirs en béton ou métal stockant un liquide alimentaire ,des canalisations d’eau potable et/ou l’étanchéité et/ou la protection anti-corrosion du béton et/ou du métal d’un équipement destiné à être en contact avec un liquide alimentaire, un procédé de traitement d’un équipement destiné à être en contact avec un liquide alimentaire et l’utilisation de 0,05 à 0,5% en poids de graphène par rapport au poids total de la résine dans une résine destinée au contact des aliments pour éviter la migration de molécules odorantes et/ou nocives dans les aliments.Resins intended for contact with food The present invention relates to a resin intended for contact with food comprising from 0.05 to 0.5% by weight of graphene relative to the total weight of the resin. It also concerns its use for the interior lining of concrete or metal tanks storing a food liquid, drinking water pipes and/or the sealing and/or anti-corrosion protection of concrete and/or metal of equipment intended to be in contact with a food liquid, a method of treating equipment intended to be in contact with a food liquid and the use of 0.05 to 0.5% by weight of graphene relative to the weight total resin in a resin intended for contact with food to prevent the migration of odorous and/or harmful molecules into food.
