Protection efficiency of compositions on base of unrefined colza oil and products of waste motor oils cleaning has been studied in the conditions of atmospheric corrosion of copper and brass in the presence of 0,1…5,0 vol.% SO 2 in air. Corrosion rate of construction materials under study can be decreased by 3,5…4 times in the presence of surface composition protective film because of retardation of anodic and cathodic reactions.
