Abstract
The present invention relates to cured compositions useful as adhesives and sealants formed by dispersing an amine-terminated polyamide curative into a base to form a composite and activating the composite forming the cured composition. Bases described include epoxies, polysulfides and cyanoacrylates. Curing mechanisms include heat and pressure activation. The amine-terminated polyamide curative has a ratio of equivalents of amine to acid groups of from about 1.05:1.00 equivalents NH.sub.X :COOH to no greater than about 1.95:1.00 when x is 1 or 2.
