Superior lubricants for superior performance

WRL-S Series

Pseudoplastic wire rope lubricants

Molyslip S series products are premium-performance lubricants 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 S series products solve 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.

WRL-S series products do not compromise. By utilizing a thickener system that exhibits pseudoplastic behavior WRL-S10 and WRL-S20 provide both excellent penetration and wash-off protection.

Molyslip WRL-S series products are 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.

WRL-S10 is a translucent grease designed to allow easy inspection of the rope

WRL-S15 is a solvent containing version of S10, designed to allow the product to be applied via a pressure sprayer

WRL-S20 is a graphite reinforced version of S10 with enhanced load carrying for arduous operations

Features and benefits

  • 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

Instructions for use

Molyslip WRL-S10 and WRL-S20 can be applied manually with a brush or swab, or via a high pressure applicator (for example a Masto type system). WRL-S15 is designed for application via pressure spray equipment.

Packaging
