Micronkote 206
Micronkote 206 is a solvent-based, PTFE solid film lubricant coating. It cures at 235 °C for 45 minutes into a bonded black film of 5-22 µm that lubricates metal-to-metal contact surfaces running at slow to moderate sliding speeds under medium to high loads.
Zinc phosphate in the formulation adds corrosion resistance. The cured film resists oils, greases and solvents, holds its lubricating function from -60 °C to +250 °C, and helps prevent fretting corrosion and seizure under sustained mechanical loading.

What is Micronkote 206?
Micronkote 206 is a black, solvent-based solid film lubricant coating built on PTFE. It is supplied as a liquid, applied by spray, brush, roller or dipping, and cured at 235 °C for 45 minutes to leave a bonded dry film 5-22 µm thick.
It is used where two metal surfaces slide against each other under load and a fluid lubricant is impractical or cannot be maintained. Micronkote 206 is part of the Micronkote dry film lubricant range.
What it is
A PTFE-based solid film lubricant coating, supplied as a solvent-borne liquid and heat-cured into a bonded dry film of 5-22 µm.
What it solves
Friction and wear on loaded metal contacts, and the fretting corrosion and seizure that follow sustained mechanical loading.
Where it is used
Metal-to-metal contact surfaces running at slow to moderate sliding speeds under medium to high loads.
Why a dry film
The lubricant is bonded to the surface instead of held as a fluid film, and stays functional from -60 °C to +250 °C, where maintaining an oil or grease film is impractical.
How Dry Film Lubrication Works
PTFE and corrosion-inhibiting solids are carried in a resin binder. Once cured, the binder anchors them to the prepared substrate as a continuous 5-22 µm film.
Under load the PTFE film shears in preference to the metal surfaces beneath it, giving a coefficient of friction of 0.05-0.07 under a 2,860 N rotating load.
Zinc phosphate in the formulation adds corrosion resistance, so the same layer that lubricates also protects the contact face.

Applications
Formulated for metal-to-metal contacts operating at slow to moderate sliding speeds under medium to high mechanical loads.
The cured film helps prevent fretting corrosion and seizure on components held under sustained mechanical loading.
The cured film is resistant to oils, greases and solvents, with fluid resistance verified to ASTM D2510 Proc. A / MIL-PRF-46010G.
The coating retains its lubricating function across a functional lubrication temperature range of -60 °C to +250 °C, and passes thermal stability testing to IEC 60068-2-12.
Zinc phosphate in the formulation adds corrosion resistance, confirmed by humidity resistance testing to EN ISO 6270-1.
Surface Preparation and Application
Curing Conditions
Cure the applied film for 45 minutes at 235 °C. Surfaces must be clean, dry and free from oil before application, and sandblasting or phosphating improves adhesion and coating life.
