ТУ У 24.6-30802090-068:2007VNII NP-282 А and VNII NP-282М А are lubricants intended for sealing and greasing attrition faces of various equipment units functioning at different loading in contact with aggressive media and gaseous oxygen at the temperature from minus 45°С up to 150°С. The lubricants may also be used in powerful mechanisms and the armature of oxygen-respiratory devices at the temperature not lower than minus 60°С.The lubricants possess increased stability against oxygen and the influence of such aggressive media as acids, amines, hydrazines. The stability decreases because of a continuous contact with nitric acid and hydrogen peroxide.Guarantee period of storage - 5 years from the day of manufacture.Table 79

CIATIM-205 is a plastic lubricant intended for capsulation and prevention of caking of immobile screw joints and seals contacting with such aggressive media as concentrated non-organic acids, alkalis, amines, alcohol, hydrazines and working within the temperature range from minus 60°С up to 50°С. The minimal temperature of the lubricant’s utilization for movable screw joints is minus 20°С.
Guarantee period of storage - 5 years from the day of manufacture.
