1 Antioxidant 
2 ash less product 
3 used in every kinds of lubrication oil, including industrial oil, transformer oil, etc 



Ethanox4701 chemical inhibitor is a kind of ash less product; it is used in every kinds of lubrication oil, including industrial oil, transformer oil, driving fluid, rail oil, quenching oil, grease and internal combustion engine oil. This product belongs to high activity hindered phenol; it has low melting point and good oil-soluble. This product is used easily and will not catch odor of phenol. If use it with ZDDP and alkyl diphenylamine together will catch synergistic effect.



Using Effects

Put E-4701and T-501 in 350SN each of 0.3% dosage, to take the RBO test, the OIT of E-4701 is 165 minutes and the T-501 is 90mins.Under the same dosage, Ethanox4701 is nearly 80% higher than T-501 in afflation.




The reference dosage in lubrication oil and transformer oil should be 0.15%-0.75%.
