Abstract: The paper aims at presenting the results of pull-off strength and abrasion resistance tests for anti-corrosive coatings on steel substrates. It contains the measured data on the thickness of manufactured coatings in the function of the applied amount of abrasive material. Three polymeric coatings were subjected for testing: chlorinated rubber, oil-phthalic and alkyd. The analogous studies were repeated for composite coatings with alumina α-Al₂O₃ filler and subsequently also for the aged (72 h, -19°C) systems. For the pull-off tests, the damage analysis of samples after failure was performed. The highest pull-off strength's values for the produced coatings were obtained for the alkyd one. Concerning the abrasion resistance it can be stated that, the addition of a filler significantly improves the system's durability, while the aging process causes its deterioration.
