Pseudoplastic wire rope lubricant


  • High-load carrying and wear reduction capability protects wires and strands from wear
  • Excellent corrosion resistance protects ropes operating in wet conditions
  • Highly adhesive, tenacious film extends re-lubrication intervals
  • Excellent low-temperature flexibility prevents flaking and cracking


Molyslip® S10 is a premium-performance lubricant specifically designed to overcome the challenge of effectively lubricating and protecting steel wire ropes. Formulated from high-quality base oils and incorporating a pseudoplastic thickener system, Molyslip® S10 solves the problem of balancing penetrating properties and wash-off resistance, without the unnecessary compromises of conventional greases.

The majority of wear and corrosion of a wire rope occurs in the core. This is hidden away from view and difficult to reach through the outer strands. Therefore an effective rope lubricant must have excellent penetration properties to deliver protection in this vital area. This is best achieved by low viscosity materials that have little resistance to flow. However, low viscosity products have poor resistance to wash-off caused by rain or water immersion, for this a tenacious high viscosity material is required. These competing and opposite demands often result in a compromise product.

Molyslip® WRL-S10 does not compromise. By utilizing a thickener system that exhibits pseudoplastic behavior Molyslip® WRL-S10 provides both excellent penetration and wash-off protection.

Molyslip® WRL-S10 is suitable for use on most wire rope types and constructions operating in a wide variety of conditions and equipment such as cranes, ports, oilfield, construction, and mining. They can also be used in applications such as ROV umbilical cables to protect from corrosion.
