The nanocapsules loaded with 2-methylbenzothiazole and 2-mercaptobenzothiazole formed by the LbL electrostatic adsorptionon the liquid core were fully compatible with both tested epoxycoatings and stable during the mixing, application and curing pro-cesses. The small size of the capsules allowed introducing theminto the coatings without a significant change in the structure andbarrier properties of the polymer matrix.
