Abstract
Epoxy resins, of the polyglycidyl ether of a polyhydric phenol type, are cured by incorporating therein a polyoxyalkylenepolyamine and an accelerator combination of piperazine and an alkanolamine, the combination having a combined weight ratio of between about 1:8 to 1:1. The accelerator combination is synergistic for accelerating the curing of a polyglycidyl ether of a polyhydric phenol cured with a polyoxyalkylenepolyamine 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.
