ABSTRACT:
Epoxy resins, particularly those of the polyglycidyl ether of a polyhydric phenol type, are cured by incorporating therein a polyoxyalkylenepolyamine usually with an accelerator such as a combination of piperazine and an alkanolamine. Rapidity of curing is further improved by substituting from about 50 wt% to 100 wt% of the dithiocarbamate salt of the polyoxyalkylenepolymine for the polyoxyalkylenepolyamine. 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.
