The ZN Series consists of a high-quality, ultra-fine grade of pure Zinc Sulfide, specifically designed for use as solid lubricant additives in both general-purpose and food industry applications. They stand out due to their exceptional tribological properties and hold a 21CFR code, indicating compliance as a food additive suitable for use in applications where there may be incidental food contact.
The ZN series is a line of solid lubricant additives based on high-purity, white synthetic Zinc Sulfide (ZnS). Its main function is to provide an excellent balance of Extreme Pressure (EP) and Anti-Wear (AW) properties, serving as a high-performance alternative to traditional dark solid lubricants.
The ZN series is the ideal choice when seeking a robust and versatile solution that combines performance and cleanliness. It is recommended over other options in the following scenarios:
Its key advantage is its chemical inertness towards yellow metals. Unlike other additives containing active sulfur, Zinc Sulfide is non-reactive and will not cause corrosion or staining on copper, bronze, or brass components. This makes it a perfect fit for applications such as worm gears with bronze crowns or friction bearings.
For an excellent balance of protection, lubricity, and cost, we recommend starting evaluations in the range of 2% to 5% by weight of the finished grease. This concentration is effective for the majority of industrial and automotive applications.
Yes. Zinc Sulfide is a stable solid compound that does not react with grease components. This ensures its full compatibility with a wide variety of thickeners (Lithium Complex, Calcium Sulfonate, Polyurea, etc.) and base oils (mineral and synthetic), facilitating its incorporation into any type of formulation.
