　　3. Packaging：Net 50kg in plastic bag lined plastic film woven bag, can also package according to customer request
　　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.
