Songwon’s new additive, Songnox L570, is a liquid butylated/octylated diphenylamine antioxidant that enhances a lubricant’s thermo-oxidative resistance by reacting with and stabilizing radicals, the company says. This protects oil from degradation and increases service life in vehicles and machinery. The additive t is recommended for use in passenger car and heavy-duty diesel engine oils, compressor oils, hydraulic fluids, metalworking fluids, turbine oils and greases. The product is stable for up to two years when stored in a dry location at temperatures between 5 and 40 degrees Celsius. Web: www.songwon.com
