Lubricore Dispersions
MoS₂ Dispersion in Oil — Ready-to-Blend Lubricant Concentrate
Pre-dispersed Molybdenum Disulfide (MoS₂) concentrate in PAO-6 carrier oil. Surface-modified, sub-micron, and stabilized against agglomeration. Drop-in EP/AW additive for gear oils, engine oils, hydraulic fluids, and industrial lubricants.
- 50% MoS₂ active content in PAO-6
- Sub-micron particle size — engineered for filterability
- Stable suspension with 12+ month shelf life
Why Raw MoS₂ Powder Fails in Oil
MoS₂ is naturally difficult to disperse in oil. Without proper surface treatment, raw MoS₂ powder can agglomerate into larger particle clusters, settle out of suspension, and create inconsistent additive distribution throughout the finished lubricant.
These dispersion challenges are especially important in oil systems, where particle size, suspension stability, filterability, and long-term homogeneity directly affect lubricant performance.
- Sedimentation can occur when untreated particles fall out of suspension.
- Agglomeration can create concentration gradients across the oil batch.
- Large clusters may affect filters, narrow oil passages, or lubricant delivery.
- Inconsistent particle distribution can reduce EP/AW performance over time.
- Oversized agglomerates can behave abrasively if they exceed the target film thickness.
These failure modes are why many formulators avoid raw MoS₂ powder for oil applications — and why Lubricore M850 was engineered as a ready-to-blend dispersion.
Lubricore M850 — Engineered for Oil Compatibility
Lubricore M850 applies a surface modification process to MoS₂ particles before dispersion. The result is a 50% MoS₂ concentrate in PAO-6 carrier oil designed for stable blending into finished lubricant formulations.
Stable Suspension
Surface-modified particles resist agglomeration during storage, handling, and blending. This helps maintain consistent concentration throughout the finished lubricant.
Filterability-Focused
Sub-micron particle size distribution is designed to reduce the risk of filter blockage when used at recommended treat rates.
Consistent EP/AW Performance
Uniform particle distribution supports consistent extreme pressure and anti-wear protection from initial use through the drain interval.
Drop-In Compatible
Pre-dispersed in PAO-6 and compatible with PAO, Group III, and Group II base stocks. No raw powder handling required.
Ready to blend. Lubricore M850 ships as a 50% MoS₂ active concentrate. A target treat rate of 0.5–3 wt% in the finished lubricant gives approximately 0.25–1.5 wt% MoS₂ in the final product. Dosing, compatibility, and blending protocol are available from our technical team.

Where Lubricore M850 Is Used
Gear Oil Formulation
Additive concentrate for finished gear oils where formulators need solid lubricant EP/AW performance without handling dry MoS₂ powder.
Engine Oil Additives
Supports friction modification on cylinder walls, camshaft lobes, and valvetrain components, especially in boundary lubrication conditions.
Hydraulic Fluids
Low treat rates can add anti-wear support to hydraulic fluids for high-pressure pump protection while maintaining formulation control.
Industrial Lubricants
Chain oils, compressor oils, and way lubricants can benefit from sub-micron MoS₂ distribution for metal-to-metal contact protection.
Metalworking Fluids
Neat cutting oils and forming fluids can use Lubricore M850 to support reduced tool wear and improved surface finish.
Specialty Greases
For formulators blending greases from base oil and thickener, Lubricore M850 provides pre-dispersed MoS₂ without dry powder handling.
Frequently Asked Questions
What is the difference between MoS₂ powder and MoS₂ dispersion?
Raw MoS₂ powder can agglomerate in oil without surface treatment, creating sedimentation, filterability challenges, and inconsistent performance. Lubricore M850 is surface-modified MoS₂ pre-dispersed in PAO-6 at 50% active content. Particles remain sub-micron and stabilized in suspension, supporting consistent EP and AW performance across the lubricant’s service interval.
How do I use Lubricore M850 in my formulation?
Lubricore M850 is a concentrate containing 50% MoS₂ by weight. To achieve 1 wt% MoS₂ in a finished lubricant, add 2 wt% Lubricore M850 to the base formulation. It is pre-dispersed in PAO-6 and compatible with many Group II, Group III, and PAO base stocks. Stir or recirculate to homogenize. Full blending protocol and compatibility data are available on request.
Will MoS₂ dispersion clog my filters?
Lubricore M850 is engineered to reduce filter-clogging risk by maintaining sub-micron particle size and stable dispersion. Filtration performance depends on final treat rate, filter rating, lubricant viscosity, and system design. If your application has specific filtration requirements, contact our team for particle size distribution and compatibility data.
Is MoS₂ dispersion compatible with conventional EP additives?
MoS₂ dispersions are generally compatible with many ZnDTP, sulfurized EP, and phosphate ester additive packages at typical treat rates. Avoid strong oxidizers or high-acid environments that can degrade MoS₂. Compatibility testing with the specific additive package is recommended before production scale-up.
What is the shelf life of Lubricore M850?
Lubricore M850 has a minimum shelf life of 12 months from manufacture date when stored at room temperature (15–30°C), away from heat sources and direct sunlight. Mild agitation or recirculation is recommended before use after extended storage to redistribute any settled particles.
