What solid lubricant powders does Powderful Solutions supply?

Powderful Solutions supplies surface-modified MoS2 (molybdenum disulfide), WS2 (tungsten disulfide), and hBN (hexagonal boron nitride) solid lubricant powders and stable oil dispersions for lubricant formulators.

Are Powderful Solutions products PTFE-free?

Yes. All Powderful Solutions solid lubricant dispersions are PTFE-free and use MoS2, WS2, or hBN as the active solid lubricant component, providing excellent anti-wear and anti-friction performance without fluorinated compounds.

What is a stable MoS2 oil dispersion?

A stable MoS2 oil dispersion is a colloidal suspension of surface-modified molybdenum disulfide particles in oil that does not settle or agglomerate. Powderful Solutions achieves stability through proprietary surface modification chemistry.

MoS₂ powder vs dispersion?

Raw powder agglomerates in oil; Lubricore M850 is surface-modified, sub-micron, stable, and ready to blend.

How to use Lubricore M850?

50% concentrate: add 2 wt% to achieve 1 wt% MoS₂ in finished lubricant. Compatible with Group II, III, PAO bases.

Will it clog filters?

No — sub-micron particle size maintained below EHD film thickness. No filter clogging at recommended treat rates.

Compatible with EP additives?

Yes, generally compatible with ZnDTP, sulfurized EP, and phosphate ester packages. Compatibility testing recommended.

12+ months at 15–30°C. Mild agitation before use after extended storage.

The Dispersion Problem

Why Raw MoS₂ Powder Fails in Oil

MoS₂ is hydrophilic and exhibits strong van der Waals attraction between particles. When blended directly into oil without surface treatment, raw MoS₂ powder agglomerates into clusters that:

Sediment out of suspension within hours at room temperature
Form concentration gradients throughout the oil batch
Block lubrication system filters and oil passages
Deliver inconsistent EP/AW performance across the drain interval
Create abrasive wear if particle clusters exceed the EHD film thickness

These failure modes are why most lubricant formulators avoid raw MoS₂ powder for oil applications — and why Lubricore M850 was engineered to solve each of them.

The Lubricore Solution

Lubricore M850 — Engineered for Oil Compatibility

Lubricore M850 applies a proprietary surface modification process to WS₂ particles before dispersion. The result is a 50% MoS₂ concentrate in PAO-6 carrier oil that:

Stays in Suspension

Surface-modified particles resist agglomeration under shear, heat cycles, and 12+ months of storage. Consistent concentration throughout the blend.

Won't Clog Filters

Sub-micron particle size distribution confirmed below EHD film thickness in target applications. No filter bypass or oil passage blockage.

Delivers Consistent Performance

Uniform particle distribution means consistent EP and AW protection from first hour of operation to end of drain interval.

Drop-In Compatible

Pre-dispersed in PAO-6 — compatible with PAO, Group III, and Group II base stocks. No additional dispersants required at typical treat rates.

Ready to blend. Lubricore M850 ships as a 50% MoS₂ active concentrate. Target treat rate 0.5–3 wt% in finished lubricant gives 0.25–1.5 wt% MoS₂ in the final product. Dosing, compatibility, and blending protocol available from our technical team.

Applications

Where Lubricore M850 Is Used

Gear Oil Formulation

Add at 1–3% to finished gear oil to achieve EP weld point improvement without ZnDTP chemistry. Compatible with synthetic and mineral gear oil base stocks.

Engine Oil Additive

0.5–1.5% in engine oil provides friction modification on cylinder walls and valve train components. Reduces boundary friction at startup and under high load.

Hydraulic Fluid

Low treat rates (0.5–1%) add AW performance to hydraulic fluids for high-pressure piston and vane pump protection without affecting viscosity or filterability.

Industrial Lubricants

Chain oils, compressor oils, and way lubricants benefit from consistent sub-micron MoS₂ for metal-to-metal contact protection in industrial machinery.

Metalworking Fluids

Neat cutting oils and forming fluids: 1–5% Lubricore M850 reduces tool wear and improves surface finish in turning, milling, and deep-drawing operations.

Specialty Greases

For formulators who blend greases from base oil + thickener: Lubricore M850 provides pre-dispersed MoS₂ without the dust handling required with dry powder.

Technical FAQ

Frequently Asked Questions

What is the difference between MoS₂ powder and MoS₂ dispersion?

Raw MoS₂ powder agglomerates in oil without surface treatment, creating sediment, filter clogging, and inconsistent performance. Lubricore M850 is surface-modified MoS₂ pre-dispersed in PAO-6 at 50% active content. Particles remain sub-micron and in stable suspension, delivering consistent EP and AW performance across the full drain 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 your finished lubricant, add 2 wt% Lubricore M850 to your base formulation. It is pre-dispersed in PAO-6 and compatible with Group II, III, and PAO base stocks. Stir or recirculate to homogenize. Full blending protocol and compatibility data available on request.

Will MoS₂ dispersion clog my filters?

Lubricore M850 is engineered specifically to avoid filter clogging. Sub-micron particle size is maintained throughout the product shelf life, and particles remain below the EHD film thickness in target applications. If you have specific filtration requirements (e.g., 3-micron absolute), contact our team for particle size distribution data.

Is MoS₂ dispersion compatible with conventional EP additives?

Yes, with caveats. MoS₂ dispersions are generally compatible with 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 your specific additive package is recommended before production scale-up.

What is the shelf life of Lubricore M850?

12 months minimum from manufacture date when stored at room temperature (15–30°C) away from heat sources and direct sunlight. Mild agitation or recirculation recommended before use after extended storage to redistribute any settled particles.
