Title
(EN) UV-CURED ELECTRICALLY CONDUCTIVE INK
(ES) TINTA CONDUCTORA ELÉCTRICA DE CURADO UV
(FR) ENCRE CONDUCTRICE DE L'ÉLECTRICITÉ POUR LE TRAITEMENT UV
Abstract
(EN)
The invention relates to a UV-cured electrically conductive ink comprising at least one monomer and a metal material which provides the ink with electrically conductive properties, wherein the metal material comprises silver particles in the form of flakes in a proportion between 10 and 30% in weight relative to the total weight of the ink, such that, after the curing of the ink by means of UV radiation, a coating is obtained, having a low silver content and being electrically conductive on the basis of 5% silver volume relative to the total volume of the coating.

Tinta conductora eléctrica de curado UV que comprende al menos un monómero y un material metálico que le confiere a la tinta la propiedad eléctricamente conductora, en donde el material metálico comprende partículas de plata en forma de copos en una proporción de entre un 10-30% en peso en relación con el peso total de la tinta, de forma que se tras el curado de la tinta mediante radiación UV se obtiene un recubrimiento de bajo contenido en plata que es eléctricamente conductor a partir de un 5% de plata en volumen respecto al volumen total de recubrimiento.
(FR)
La présente invention concerne une encre conductrice de l'électricité pour le traitement uv qui comprend au moins un monomère et un matériau métallique qui confère à l'encre la propriété de conduction de l'électricité, lequel matériau métallique comprend des particules d'argent en forme de flocons selon une proportion comprise entre 10-30% en poids par rapport au poids total de l'encre, de sorte qu'après le durcissement de l'encre par rayonnement UV, on obtient un revêtement à faible teneur en argent qui est conducteur de l'électricité à partir de 5% d'argent en volume par rapport au volume total de revêtement.
