Effect of physical and chemical ageing on barrier properties of epoxy coating

Construction and Building Materials, 2023
This work describes the change of gas permeability of epoxy coatings thermally aged at different temperatures from 50 to 200 °C in order to address their barrier properties for protecting concrete in civil engineering industry. Argon permeability characterization tests were carried out on samples either coated on concrete or aged as free standing films.
