A network structure and adhesive properties of low-cross-linking density cured epoxy resins

Abstract A network structure and the mechanical properties, such as stretching and adhesive properties of low cross-linking density cured epoxy resin (CER-L), were investigated by swelling test, tensile test, and temperature dependence of dynamic viscoelastic properties. CER-Ls were synthesized with three different primary monoamines and diepoxy. Even though cross-linking density of the three CER-Ls was low, they showed adhesive properties, modulus, and strength comparable with those of high-cross linking density CER.
