Title
(EN) SYNERGISTIC PAINT REMOVING COMPOSITION
(FR) COMPOSITION SYNERGETIQUE DE DECAPANT DE PEINTURES
Abstract
(EN)
Disclosed is a synergistic paint removing composition comprising a particular selection of a plurality of known solvents in very specific proportions, namely: from 20 to 45 % of aromatic hydrocarbons; from 15 to 25 % of dimethylformamide; from 15 to 25 % of N-methyl pyrrolidone; from 5 to 15 % of a water-immiscible compound selected from the group consisting of terpene derivatives, oleoresins and mixtures thereof; and from 0.5 to 4 % of at least one wetting agent, all the above percentages being expressed by weight. This composition is partially miscible in water even though some of its constituents are not water miscible, thereby making the composition easy to wash and thus preventing oily film to be left on the treated substrate. The composition according to the invention is normally in a liquid form. If desired, for some applications, a thickening agent can be added thereto to 'convert' it to a gel.
(FR)
On décrit une composition synergétique de décapant de peintures qui comprend un choix précis de plusieurs solvants connus présents en des proportions très spécifiques, à savoir: 20 à 45 % d'hydrocarbures aromatiques; 15 à 25 % de diméthylformamide; 15 à 25 % de N-méthyle pyrrolidone; 5 à 15 % d'un composé, non miscible avec l'eau, choisi dans le groupe consistant en des dérivés de terpènes, des oléorésines et leurs mélanges; et 0,5 à 4 % d'au moins un agent de mouillage, tous ces pourcentages étant exprimés en poids. Cette composition est partiellement miscible avec l'eau, même si certains de ses constituants ne le sont pas, ce qui la rend facile à laver et évite donc de laisser subsister une pellicule huileuse sur un substrat traité. Cette composition se présente normalement sous forme liquide. Le cas échéant, on peut lui ajouter pour certaines utilisations un épaississant qui la 'transforme' en gel.
