EPOXY MATERIALS AND THE USE THEREOF

摘要

Thermoset compositions are disclosed. Such thermosets are the reaction product of an ambient temperature liquid epoxy-terminated prepolymer, a short chain polyalkylene glycol diglycidyl ether, optionally a second epoxy and/or a filler, and a curing agent comprising at least one amine or polyamine. Said reaction product provides a thermoset which has polyurethane like processing and flexibility with good thermal and hydrolytic stability and improved toughness and strength. Such thermosets can be used in applications such as for sealants, adhesives, coatings, gaskets, jointing and castings.
