ABSTRACT:
A novel epoxy resin curing accelerator comprises a mixture of piperazine, N-aminoethylpiperazine (AEP) and triethanolamine (TEA). The resins comprise a vicinal polyepoxide, a curing agent, and an amount of piperazine, AEP and TEA mixture effective for accelerating the cure of the polyepoxide. The accelerator combination is synergistic for accelerating the curing of an epoxy resin cured with an amine at ambient or elevated temperatures. The epoxy resin products are useful in protective coatings, adhesives, seamless and terrazzo flooring, castings, laminates, and in grouting, potting, encapsulating, caulking and sealing compositions.
