Abstract
Thermoset elastomer compositions are disclosed. Such elastomers are the reaction product of (a) an ambient temperature liquid epoxy-terminated prepolymer formed by reacting a polyoxyalkyleneamine having a molecular weight of from 3000 to 20,000 with an excess of epoxide, wherein the polyoxyalkyleneamine has at least 3 active hydrogen atoms and (b) a curing agent comprising at least one amine or polyamine having an equivalent weight of less than 200 and having 2 to 5 active hydrogen atoms. Such elastomers can be used in applications such as for sealants, adhesives, coatings, gaskets, jointing and cast elastomers.
