ABSTRACT:
A latent curing agent for an epoxy resin comprising boron trifluoride on a cross-linked polymer support having at least 10% by weight of pendant pyridine groups. The polymer support is preferably about 25% to 40% cross-linked, and preferably in the form of porous, macroreticular beads having average diameters of less than 30 .mu.m. The combination of this latent curing agent admixed with an epoxy resin is also disclosed, as is the process for making and using the same.
