Additin® RC 7115

Type

Highly effective, high temperature stable phenolic antioxidant

Application

• Hydraulic fluids
• Turbine and compressor oils
• Greases
• Gear oils
• Natural/synthetic esters
• Polyalkyleneglycols
• Motor oils

Additin RC 7115 is a non-discolouring, highly effective antioxidant with broad applicabability. The superior effectiveness over other mono- and dimeric phenolic antioxidants is related to the unique chemical structure of Additin RC 7115. It is not only a radical scavenger but is, at the same time, able to deactivate catalytically active, dissolved copper by complexation. Due to the high molecular weight, Additin RC 7115 has a low evaporation tendency and is therefore very well suited for high temperature applications. By combining Additin RC 7115 with aminic antioxidants, e.g. Additin RC 7130, RC 7135 LD or copper deactivators, e.g. Additin RC 8221, the oxidation inhibition properties of Additin RC 7115 can be further increased.

Solubility

Additin RC 7115 is easily soluble in most mineral oils and synthetic base stocks. However, it is necessary to verify the solubility in the base oils used and the compatibility with other additives.
