The WL Series is a finely graded mixture of white chemicals, specifically designed to be used as solid lubricant additives in white greases. Their outstanding tribological properties provide a comprehensive solution meticulously designed to meet the unique demands of applications requiring colorless lubricants and offer enhanced versatility to suit a wide range of applications.
The WL (White Lubricants) series is a family of ultra-high-performance solid lubricant additives, formulated from synergistic inorganic compounds that are white in color. Its primary function is to provide exceptional Extreme Pressure (EP) load-carrying capacity and Anti-Wear (AW) protection, without the color contamination associated with traditional solid lubricants like Molybdenum Disulfide (MoS2) or graphite. It is the ideal solution for creating high-performance white or light-colored greases.
The WL series is the preferred choice for applications where cleanliness and aesthetics are critical, or when maximum EP/AW performance is required. Key examples include:
WL20 delivers significantly superior Extreme Pressure (EP) and Anti-Wear (AW) performance. While additives like PTFE are excellent friction reducers under low loads, their ability to withstand extreme shock loads is limited. WL20 provides robust protection under boundary lubrication conditions where other white lubricants would fail, offering a complete solution for both lubricity and load-carrying capacity.
We recommend starting evaluations in the range of 3% to 5% by weight of the finished grease. For extremely severe applications, a 5% treat rate has demonstrated exceptional results, as reflected in the technical data. Our team can assist you in finding the ideal cost-performance balance for your specific formulation.
Yes. The WL series consists of chemically inert solids, ensuring excellent compatibility with a wide variety of base oils (mineral, synthetics like PAO and esters) and thickeners (Lithium soaps, Lithium Complex, Calcium Sulfonate, Polyurea, etc.). It is incorporated using standard grease manufacturing processes, added during the cooling phase before final homogenization.
