Pre-dispersed Tungsten Disulfide (WS₂) concentrate in PAO-6 carrier oil. Surface-modified, sub-micron, and stabilized for use in high-performance gear oils, engine oils, hydraulic fluids, and industrial lubricants.
WS₂ particles exhibit strong inter-particle attraction. In raw powder form, WS₂ can form compact agglomerates when introduced directly into oil, creating sedimentation risk, inconsistent particle distribution, filterability issues, and performance variability over time.
Lubricore W850 was developed to address these formulation challenges. Powderful Solutions applies a surface modification treatment to WS₂ particles before dispersion in PAO-6, producing a 50% WS₂ concentrate designed for stable incorporation into finished lubricants.
Modified particles are designed to resist re-agglomeration during storage, blending, shear, and thermal cycling, helping maintain uniform WS₂ distribution.
Sub-micron particle distribution supports lubrication performance while helping reduce the risk of abrasive oversized clusters.
Liquid dispersion eliminates direct dry powder handling, reducing dust exposure and simplifying the blending process.
Dispersed in PAO-6 and suitable for use with PAO, Group III, and Group II base stocks at recommended treat rates.
Pre-dispersed, surface-modified WS₂ concentrate designed for direct blending into engine oils, gear oils, hydraulic fluids, and metalworking fluids. Built for formulators who need the performance of WS₂ without raw powder handling or uncontrolled agglomeration.

WS₂ dispersion can support EP and AW protection in hypoid, worm, spiral bevel, and industrial gear oil formulations.
Used to support boundary friction reduction on cylinder walls, camshaft lobes, and valvetrain components under startup and high-load conditions.
Relevant where low friction, high load capacity, and thermal stability are required in high-performance lubricant systems.
Can be used as an AW additive in high-pressure piston and vane pump applications when filtration and compatibility requirements are validated.
Neat cutting oils, honing fluids, and deep-drawing lubricants can use WS₂ to support tool life, surface finish, and metal-to-metal contact protection.
Suitable for specialized lubricant applications involving high temperature, vacuum, low friction, or demanding tribological conditions.
