The Formulator’s Dilemma: High Performance Without Corrosion or Dark Color

For lubricant specialists, the perfect balance is the holy grail.

How do you create a grease that withstands extreme pressure and resists wear, but also doesn’t harm copper components and maintains a clean color?

This question resonates in laboratories worldwide. Traditional extreme pressure (EP) and anti-wear (AW) additives, like molybdenum disulfide (MoS₂), are very effective, but often come with a significant disadvantage: their black color. In applications where visual cleanliness is crucial, such as in food processing or consumer goods equipment, a black grease can be a major problem.

A more critical technical issue lies in copper corrosion. Many common EP/AW additives contain active sulfur or other aggressive compounds that can react with copper and its alloys. While MoS₂ itself is generally stable, impurities from its synthesis can contribute to corrosive behavior. These reactions form corrosive sulfides on the metal’s surface, which can degrade sensitive components like brass and bronze bushings, leading to equipment failure and reduced service life.

Innovamat WL Series: A High-Performance, Mo-Free Alternative

At Innovamat, we understand this challenge. That’s why our R&D team developed the WL series, an innovative solution that redefines what an EP/AW additive can do. The WL series is a Mo-free solid lubricant designed specifically to overcome the limitations of conventional additives.

How the WL Series Solves the Problem:

  • Superior EP/AW Performance: In lithium complex grease formulations, the WL series has shown outstanding results, with wear scar diameters below 0.5 mm and weld loads exceeding 315 kgf. This means your lubricants can withstand the most demanding conditions.
  • No Copper Corrosion: This is a key technical advantage. Our Mo-free formulation achieves its EP/AW performance through a different, non-corrosive mechanism. It does not rely on aggressive compounds that react with copper. This ensures your lubricants will pass stringent corrosion tests and protect critical components, extending the service life of the equipment they lubricate.
  • Immaculate White Color: The WL series is completely white, making it the ideal substitute for MoS₂ and other dark additives. You can now formulate high-performance greases that are perfect for applications where aesthetics and cleanliness are key.
  • Optimized Particle Size: With strict control over particle size, the WL series ensures uniform dispersion in the grease, preventing clogging of lubrication lines and making it suitable for automated dispensing systems.

By choosing the WL series, formulators no longer have to sacrifice wear protection for cleanliness or copper protection. They can achieve all three, elevating the quality of their products and meeting the demands of an increasingly discerning market.

Are you ready to take your formulations to the next level? Discover how the Mo-free WL series can transform your lubricants.
