Note:

To achieve the  optimum performance of antioxidant 4720, the application temperature should be between room temperature and  125℃. When n,n'-di-sec-butyl-1,4-phenylenediamine is used for gasoline, the added amount should dependent on the content of  olefins and storage conditions, usual addition level is  0.001-0.01%。Cracked gasoline should be directly added at the fractionation exit.
Packing: In iron drum, 188KG/drum. 

Storage: Stored in cool, airy and dry place. Transported as common chemicals.
