The paper presents an assessment of the effect of artificial aging conditions on the properties of varnish coating systems used for effective masking of military equipment and the service life of this type of coating protections was determined. As part of the research, operational exposures were simulated in the form of: accelerated corrosion tests in an artificial atmosphere in accordance with PN-EN ISO 12944-6, a continuous condensation environment at elevated temperature in accordance with the PN-EN ISO 6270-2 standard and short-term temperature impact up to 250 °C. The evaluation of the properties was carried out on the basis of measurements of the surface geometric structure and adhesion by the peel-off method. On the other hand, measurements of specular gloss, color in the range of 400-700 nm and reflectance in the range of 350-1200 nm were made in relation to the requirements of the Polish Defence Standard NO-80-A200. The operational durability of the paint coatings was assessed in terms of damage in accordance with PN-EN-ISO 4628.
