    摘要: Resistance to thermal shock of certain anhydride cured epoxy resins is unexpectedly enhanced by addition of a diamide of a polyoxyalkylenepolyamine-urea condensate. This superior resistance does not appreciably compromise heat deflection properties. The resins comprise a vicinal polyepoxide, a curing amount of a certain bicyclic anhydride and an effective amount of a diamide of a polyoxyalkylenepolyamine-urea condensate having a molecular weight of from about 4000 to 4500.

    摘要: An improved curable epoxy resin composition of a vicinalpolyepoxide and an effective amount of a novel polyether urea curing agent is disclosed. The improved curable epoxy resins which are useful as coatings, castings, sealants, and adhesives show improved tensile shear strength, flexural strength, and ultimate elongation. The novel polyether urea curing agents of the instant invention are characterized by terminal primary amino groups and are formed by reaction of polyoxyalkylenepolyamines with urea, urea forming compounds, or bifunctional isocyanates.A preferred curing agent includes a mixture of a novel polyether urea formed by reaction of a polyoxypropylenepolyamine having a molecular weight of from about 200-2000 and an effective amount of urea; and another known epoxy resin curing agent such as polyoxyalkylenepolyamine in ratios of from about 5:1 to 1:5 by weight.

    摘要: 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.

    摘要: An epoxy resin composition is disclosed. The composition comprises a polyepoxide and a curing amount of a bis(hydrogen maleate) derivative of a polyoxypropylenediamine. This composition when cured produces unexpectedly superior encapsulations which are more flexible and less brittle than those of the prior art.
