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

Physical Properties

  • Hardness – 1.0 – 1.5 Moh’s scale.
  • Thickness – 0.000020 inch (0.5 microns) “maximum”
  • Appearance – silver-gray, polished rhodium
  • No binders, adhesives or solvents
  • Cure Time – no cure time required
  • Near ambient temperature application process (20-35℃)
  • Magnetism – non-magnetic
  • Conductive
  • Substrates – bonds to metals, platings, plastics and man-made materials

Functional Properties

  • Coefficient of Friction inclined plane method, against itself
  • Temperature Range:
    • Lubricates from -306℉ to +1000℉ (-188℃ to +538℃) normal atmosphere
    • Lubricates up to +2400℉ (+1316℃) under 10-14 Torr vacuum
  • Chemical Stability – insert and non-toxic
  • Corrosion Resistance – minor delay of corrosion, not corrosion inhibitor, does not induce corrosion
  • As A Substrate – accepts most paints and is compatible with most solvents, fuels, and oils
  • Load Capacity – same as the substrate, to approx. 350,000 psi (approx. 2,450 MPa)
  • LOX Compatibility – insensitive to detonation by or in the presence of liquid and gaseous oxygen
  • Distortion/Stress – will not distort existing surfaces or create additional stresses
  • Biocompatible – USP (United States Pharmacopoeia) Class 6 and ISO-10993 tested, US-FDA approved
  • Very low Outgassing (ASTM-595) Average TML = 0.10-0.13%, Average CVCM=0.00-0.02%
  • Radiation environment stable from low earth orbit (LEO) to a nuclear containment vessel
  • Gamma-ray, ethylene oxide and autoclave sterilization stable
