Abstract
A liquid or viscous curable adhesive composition having a prolonged pot life which is composed of a liquid or viscous curable resin which has, preferably evenly and randomly dispersed therethroughout, a multiplicity of rupturable microcapsules containing a curing agent in an amount sufficient to cure the resin. The microcapsules are rupturable upon the application thereto of external pressure, or other mechanical manipulation. Upon rupture, the curing agent is released into coacting relationship with the curable resin and forms therewith an activated adhesive composition.
