Title (EN) ROOM TEMPERATURE IONIC LIQUID CURING AGENT
(FR) AGENT DE DURCISSEMENT LIQUIDE IONIQUE À TEMPÉRATURE AMBIANTE
Abstract: front page image
(EN)Epoxy curing agents are disclosed having an epoxy curing agent comprising at least one room temperature ionic liquid salt, the room temperature ionic liquid salt being a reaction product of (a) at least one polyalkylene polyamine compound represented by formula (I) : wherein x, y, and z are integers of 2 and 3, m and n are integers of 1-3; and (b) an organic acid having pKa (the negative of the logarithm of the acid dissociation constant) less than 6. The liquid salt is a stable liquid at a temperature greater than 15℃. Curable epoxy-based compositions including the curing agent and articles formed by the curable epoxy-based compositions are also disclosed.
(FR)L'invention concerne des agents de durcissement époxy ayant un agent de durcissement époxy comprenant au moins un sel liquide ionique à température ambiante, le sel liquide ionique à température ambiante étant un produit réactionnel de (a) au moins un composé polyalkylène polyamine de formule (I), dans laquelle x, y et z sont des nombres entiers parmi 2 et 3, m et n sont des nombres entiers compris entre 1 et 3; et de (b) un acide organique ayant un pKa (négatif du logarithme de la constante de dissociation acide) inférieur à 6. Le sel liquide est un liquide stable à une température supérieure à 15 °C. L'invention concerne également des compositions durcissables à base d'époxy comprenant l'agent de durcissement, et des articles formés par les compositions durcissables à base d'époxy.
