Extreme-Pressure Additives (EP Additives)
The tribological properties of lubricants can be clearly improved by adding extreme-pressure additives (also calles high-pressure additives). LUBIO® EP additives prevent the welding of the metallic materials under extreme pressure and / or load conditions by means of reaction with the material surfaces. The LUBIO® EP series contains EP additives which are both soluble in oil and in water.
