Abstract
Compositions comprising thiol-terminated sulfur-containing prepolymers, curing agents reactive with the thiol-terminated sulfur-containing prepolymers, and ionic liquid catalysts, useful in aerospace sealant applications are disclosed. The use of ionic liquid catalysts provides curable sealant compositions having an extended working time and a rapid cure rate.
