SP9022 radiator sealant. It reliably and quickly eliminates leakages: brass, aluminum, and composite radiators with plastic tanks, heater furnaces, joints of radiator hoses and the heater, gaskets of the unit head, pumps and thermostats, valves and regulators. It prevents leakages in the future. It leaks together with the cooling fluid from the crack or the hole, polymerizes under the impact of temperature fluctuations, and forms a strong plug stopping the leakage. It is not washed off and painted. It does not plug radiator tubes and the heater furnace. It is safe for steel, cast iron, plastic, aluminum, rubber, and polymetallic parts. It does not interact with anti-corrosive and other functional coolant (anti-freeze) additives. It can be used in cooling systems filled with anti-freeze (coolant) or water. The package is calculated for the cooling system with the volume of up to 17L.
