VANLUBE RI-ZSN Lubricant Additive is a neutral zinc salt of high purity synthetic dinonylnaphthalene sulfonic acid. It is a classic amphiphilic molecule which possesses a strong polar group for metal surface affinity at one end, and an umbrella-shaped oleophilic portion of dinonylnaphthalene at the other end providing a protective monolayer. The sulfonate monolayer formed on the metal surface effectively reduces the permeation of oxygen and water to the metal surface, which eliminates the wet oxidation process. This product could also enhance oxidative stability and EP/AW performance of lubricants when used in combination with primary antioxidants and other EP/AW additives. VANLUBE RI-ZSN Lubricant Additive is oil and solvent-soluble. It can be used in most petroleum based products and many synthetic oil-based products. It is also compatible with additives such as antioxidants, antiwear and extreme pressure agents, and other corrosion inhibitors used in industrial oils and greases. However, it is always prudent practice to check the solubility in the base stocks used, and the compatibility with other additives, before using VANLUBE RI-ZSN Lubricant Additive.
