The RENOLIN B series is based on selected mineral base oils. High-quality additives improve the ageing and oxidation stability.  They also guarantee excellent corrosion protection properties (steel and iron materials). Synergistically acting copper deactivators protect copper / yellow metal materials.  The selected Anti-Wear- / mild EPadditives based on zincdialkyldithiophosphates protect hydraulic pumps, motors, components and machine elements from wear (at low and high temperatures and at high loads).  The RENOLIN B oils are mineral oil-based hydraulic fluids according to DIN 51524-2 (demulsifying, zinc-containing) and lubricating oils according to DIN 51517.
