Pre-dispersed Tungsten Disulfide (WS₂) concentrate in PAO-6 carrier oil. Surface-modified, sub-micron, stabilized. The ready-to-blend solid lubricant for gear oils, engine oils, and high-performance industrial lubricants.
WS₂ particles exhibit strong inter-particle van der Waals attraction. In raw powder form, WS₂ forms compact agglomerates that sediment within hours of being blended into oil — creating filter bypass risks, concentration gradients in bulk storage, and performance drop-off between relubrication intervals.
Lubricore W850 eliminates these failure modes. Powderful Solutions applies a proprietary surface modification treatment to WS₂ particles before dispersion in PAO-6, producing a stable 50% WS₂ concentrate that:
Modified particles resist re-agglomeration under shear, thermal cycling, and 12+ months storage. Uniform WS₂ concentration throughout the batch.
D50 maintained below EHD film thickness for the target application — ensures lubrication action, not abrasion.
No dry powder dust, no PPE requirements for powder handling. Pre-dispersed liquid drops directly into blending tanks.
Dispersed in PAO-6 — fully compatible with PAO, Group III, and Group II synthetic base stocks at standard treat rates.
Pre-dispersed, surface-modified WS₂ at maximum performance grade. Ready-to-blend into engine oils, gear oils, hydraulic fluids, and metalworking fluids. The highest-performance solid lubricant additive concentrate available.

1–3% in synthetic gear oil delivers WS₂ tribofilm EP protection for hypoid, worm, and bevel gears. Exceeds sulfurized EP weld point performance without sulfur.
0.5–1.5% in SAE 5W-30 / 5W-40 for boundary friction reduction on cylinder walls. Measurable fuel economy improvement in ASTM Sequence VI testing.
Where maximum EP performance and minimum friction are both required. WS₂ is the only solid lubricant delivering sub-0.05 COF with >300,000 PSI load capacity.
AW additive for high-pressure piston and vane pumps operating at >350 bar. Sub-micron WS₂ passes fine filtration requirements at recommended treat rates.
Neat cutting oils, honing fluids, and deep-drawing lubricants: WS₂ reduces tool wear, extends tool life, and improves surface finish vs. chlorinated EP compounds.
High-vacuum and cryogenic lubricants for space mechanisms, clean rooms, and semiconductor processing. WS₂ stable from −270°C in vacuum to 650°C in air.
