ABSTRACT:
A mixture of an amine-terminated liquid polymer and a non-cycloaliphatic epoxy resin cures rapidly at ambient temperatures under water while displacing water from substrate surfaces and bonding strongly thereto. The mixture comprises (A) 1 equivalent of at least one non-cycloaliphatic epoxy resin, (B) from about 0.01 to about 1.5 equivalents of at least one amine-terminated liquid polymer having a carbon-carbon backbone, (C) optionally, a chain extender or crosslinker, (D) optionally, a curing agent, and (E) optionally, other compounding ingredients. The mixture is useful as an underwater repair putty, adhesive, coating or the like.
