MoS₂ Coatings

MoS₂ Coatings

Molybdenum Disulfide (MoS₂) coatings are dry film lubricants that excel where traditional oils or greases fail. At Advanced Coating Technologies Inc., our MoS₂ coatings are engineered to reduce friction and prevent galling in high-vacuum, high-load, and high-temperature environments—without the need for liquid lubricants.

These coatings are critical in aerospace, defense, vacuum systems, and precision instrumentation, where clean, efficient motion is vital. MoS₂ coatings offer excellent adhesion and are applied via spray or vacuum deposition methods to deliver consistent, reliable performance under pressure.

Key Benefits

Ultra-Low Friction Coefficient
Minimizes friction between moving parts, leading to smoother operation and reduced energy consumption.


Operates in Vacuum and Extreme Temperatures
Designed to perform reliably in both vacuum conditions and extreme temperature ranges, ensuring versatility in diverse environments.
Dry Film Lubrication—No Residue or Mess
Provides effective lubrication without the need for oils or greases, eliminating residue buildup and simplifying maintenance.
Prevents Seizing and Galling
Reduces the risk of metal-to-metal contact, preventing wear and potential failure in critical applications.

Enhances Component Lifespan
Extends the durability of parts by reducing wear, resulting in lower replacement costs and improved reliability.
Reliable in Aerospace and Space-Grade Applications
Engineered to meet stringent standards, ensuring performance and safety in demanding aerospace environments.
