Title
(EN) CURABLE EPOXY COMPOSITION COMPRISING IMIDAZOLIUM SALTS AND METHOD FOR CURING SAME
(FR) COMPOSITION ÉPOXY DURCISSABLE COMPORTANT DES SELS D'IMIDAZOLIUM ET SON PROCÉDÉ DE DURCISSEMENT
Abstract
(EN)
Disclosed are curable epoxy compositions comprising imidazolium monocarboxylate salts as curing catalysts and method for curing same. The imidazolium monocarboxylate salt is suitable for use as latent catalysts that effect curing upon heating to a curing temperature threshold. The curable compositions prepared therefrom are used to prepare coated substrates, and to produce conformally sealed printed wiring boards. Of particular utility are curable compositions comprising 2-ethyl-4-methyl imidazolium monocarboxylate salts.
(FR)
L'invention concerne des compositions époxy durcissables, qui comportent des sels monocarboxylates d'imidazolium en tant que catalyseurs de durcissement, et un procédé de durcissement de ces compositions. Le sel monocarboxylate d'imidazolium est approprié pour une utilisation en tant que catalyseurs latents qui effectuent un durcissement lors d'un chauffage à un seuil de température de durcissement. Les compositions durcissables, préparées avec ces sels, sont utilisées pour préparer des substrats revêtus, et pour produire des cartes imprimées scellées de façon conforme. Les compositions durcissables comportant des sels monocarboxylates de 2-éthyl-4-méthyl imidazolium sont particulièrement utiles.
