Utilization of wastes of vegetable oils production for preparation of protective compositions against atmospheric corrosion of steel goods

Abstract. Protective coatings on base of wastes of vegetable oils production protect carbon steel against atmospheric corrosion with sufficiently high efficiency. In open site after 6 months exposition of steel samples covered by these compositions, protective effect reaches 80%. Insertion of 20% of wastes to vegetable oils (colza and sunflower-seed oils) allows to increase the protective effect by 10 %. Retardation of steel corrosion is caused by slowing down anodic reaction at the coating presence. The coatings under study are high producible because they have small thickness (20-30 |im} and their putting on steel surface does not demand preheating (temperature is 20-25°C).
