Amine Antioxidant for lubricating oil
AO 57 Amine Antioxidant
AO 57 Amine antioxidant is butyl octyl diphenylamine. As an excellent high-temperature antioxidant, it has good thermal stability, prominent oxidation resistance under high temperatures, good oil solubility as well as compatibility with other additives. It can be widely used for high-grade engine lubricants, heat-conducting oils, high-temp. chain oils, hydraulic oils, compressor oils, turbine oils, and other industrial lubricant oils, all kinds of lubricating grease and fuel oil. The recommended treatment rate is 0.2-1.0%.
