Abstract

La présente invention concerne un corps à revêtement thermochromique de type à deux teintes à chauffer. Plus particulièrement, la présente invention concerne un corps thermochromique de type à deux teintes à chauffer, dans lequel un agent de revêtement comprenant une composition thermochromique et un agent de revêtement ne comprenant pas de composition thermochromique sont appliqués de façon à obtenir des couleurs différentes lors de l'application de la couche de revêtement à des fins de traiter la surface du corps à chauffer auquel la chaleur est appliquée. Le corps à revêtement thermochromique de type à deux teintes à chauffer permet ainsi à un utilisateur de vérifier à l'œil nu, lors de l'utilisation, si le corps est chauffé à une température prédéterminée par de la chaleur. En outre, le corps est revêtu de couleurs d'au moins deux teintes, ce qui permet d'obtenir une amélioration esthétique plus performante en termes de conception, même avant l'utilisation.
