4. Uses：。Mainly for the automotive urea solution, applicable to all countries iv, v, euro iv, euro 5 emissions standard of all kinds of commercial vehicles, cars, large engineering machinery such as diesel engine SCR system. In SCR technology, automotive urea solution is a kind of nitrogen oxide (NOX) selective catalytic reductant, non-toxic nitrogen oxides can be converted to nitrogen gas and water, reduce exhaust of toxic emissions, reduce NOX in diesel exhaust pollution.
5. Storage: Stored in cool and ventilated, avoid light place.
