Dicronite® dry lubrication is valued by the aviation industry for its ultra-low friction, precision tolerances (maximum 0.5-micron thickness) and wide temperature range (-188C to +538C), as well as its low-temperature application process that does not affect the more exotic metals used in cutting-edge defense applications. Meets AMS2530 specification. AS9100 certified and NADCAP accredited facilities. Companies including Boeing, EADS, General Dynamics and Parker Hannifin use Dicronite® dry lubrication for:
- Hydraulic valve and connector lubrication
- Anti-galling/anti-seize protection for connectors, fasteners, and rivets
- Flanges and couplings in fueling systems
Technical Specifications
Key to Dicronite® dry lubrication’s wide range of applications are its:
- Ultra-low coefficient of friction
- Precision film thickness of 0.5 microns maximum (0.000020 inches)
- Wide functional temperature span – 188℃ to +538℃ (up to +1316℃ in vacuum)
- Near ambient temperature (max 35℃) application process
Based on these key values, Dicronite® dry lubrication is proven worldwide for:
- Friction and wear reduction
- Anti-seize / anti-galling / anti-fretting
- Plastic mold release and flow enhancement
- Co-lubrication enhancement in combination with oils and greases
- Co-deposit with Ni, Cr, Ti and many other coatings
- In place of conventional lubricants in high-vacuum/temperature situations
