Epoxide adhesives matrix resins

A thermoset polymer containing one or more epoxide groups and curable by reaction with amines, alcohols, phenols, carboxylic acids, acid anhydrides, and mercap-tans. It has been primarily used as a matrix resin in composites and adhesives. 

Simple formulation with the epoxy resin is not satisfactory as reactive groups such as amines present in the epoxy hardener compete with the carboxyl groups in reaction with epoxy groups (v. Toughened epoxide adhesives). As a result, very little RLP is incorporated into the matrix because the epoxy group has a much higher reactivity towards... 

Epoxy resins are among the most important of the high performance thermosetting polymers and have been widely used as structural adhesives and matrix for fiber composites. Epoxy resins are characterized by the presence of epoxide groups before cure, and they may also contain aliphatic, aromatic, or heterocyclic structures in the backbone. The epoxy group can react with amines, phenols, mercaptans.
