Title
(EN) REMOVAL OF ELECTROLUMINESCENCT MATERIALS FROM SUBSTRATES
(FR) ÉLIMINATION DE MATÉRIAUX ÉLECTROLUMINESCENTS CONTENUS DANS DES SUBSTRATS
Abstract
(EN)
A process for removing an electroluminescent material from a substrate. The process includes providing a substrate having an electroluminescent material disposed on a surface thereof. The process further includes contacting the substrate with a composition. The composition includes a hydroflourocompound an organic solvent that forms an azeotrope with the hydroflourocompound when mixed with the hydroflourocompound.
(FR)
L'invention concerne un procédé d'élimination d'un matériau électroluminescent contenu dans un substrat. Le procédé consiste à utiliser un substrat comprenant un matériau électroluminescent disposé sur une surface de celui-ci. Le procédé consiste en outre à mettre en contact le substrat avec une composition. La composition comprend un composé hydrofluoré et un solvant organique qui forme un azéotrope avec le composé hydrofluoré lorsqu'il est mélangé avec le composé hydrofluoré.
