Structural study of boundary layers in a rubber-epoxy resin-ammonium chloride system

The Effect of the Filler on the Curing Kinetics of a Phenol–Urethane Composite

“…A factor leading to the formation of an intermediate layer is the selective sorption of the epoxy resin, on account of which the adhesive layer is depleted of curing agent, and stoichiometry of the composite is lost. Semenovich et al [9] showed that the incompletely cured layer of polymer may be extensive.…”
