Study of amine curing agent structural impact on barrier properties in epoxy systems

A series of modified amine curing agents AMIKOR based on amine adducts, Mannich bases, and their combinations has been developed. The structures of the synthesized samples were verified by IR spectroscopy. The chemical resistance of varnish epoxy systems based on the synthesized and commercial curing agents to distilled water, sulfuric acid, sodium hydroxide solution, and toluene was investigated using gravimetric sorption measurements. The characteristics of diffusion processes were assessed by determining diffusion coefficients.
