Title
(EN) CURABLE COATING COMPOSITIONS
(FR) COMPOSITIONS DE REVÊTEMENT DURCISSABLES
Abstract
(EN) Disclosed herein are curable compositions comprising an epoxide-functional polymer, a curing agent capable of reacting with the epoxide-functional polymer that is activatable by an external energy source, and a fluoropolymer that is substantially free of a reactive functional group. The epoxide-functional polymer may be a solid epoxide-functional polyurethane comprising a di-isocyanate. Also disclosed are articles comprising one of the compositions in an at least partially cured state positioned between first and second substrates. Also disclosed are methods of forming an adhesive on a substrate.
(FR) Sont divulguées des compositions durcissables comprenant un polymère à fonction époxyde, un agent de durcissement capable de réagir avec le polymère à fonction époxyde qui peut être activé par une source d'énergie externe, et un fluoropolymère qui est pratiquement exempt d'un groupe fonctionnel réactif. Le polymère à fonction époxyde peut être un polyuréthane solide à fonction époxyde comprenant un diisocyanate. L'invention concerne également des articles comprenant l'une des compositions dans un état au moins partiellement durci positionnée entre des premier et second substrats. L'invention concerne en outre des procédés de formation d'un adhésif sur un substrat.
