ADDITIN® RC 7135 LD

Additin® RC 7135 LD is a liquid aminic antioxidant to be widely used in many lubricant applications. The life time of lubricants can be extended by the addition of Additin® RC 7135 LD. (proven in oxidation tests such as TOST (ASTM-D 943) and RBOT (ASTM-D 2272)). An outstanding feature of Additin® RC 7135 LD versus other aminic antioxidants such as nonylated diphenylamine is the low sludge and carbon residue formation during the oxidation process. Due to the high molecular weight, the volatility of Additin® RC 7135 LD is lower than those of other aminic and phenolic antioxidants. As a result Additin® RC 7135 LD can be applied very well for high temperature applications.

Combinations of Additin® RC 7135 LD e.g. with the phenolic antioxidant Additin® RC 7115, and / or Copper deactivators such as Additin® RC 8239 show synergistic effects and help to increase the oxidation stability.

Please note that Lubricants formulated with Additin® RC 7135 LD may discolor in use. This has no negative effect on the lubricant characteristics and performance. Soluble in mineral oils and synthetic base oils. However, it is necessary to verify the solubility in the base oils used and the compatibility with other additives.
