Slik-Seal with PTFE

SLICKSEAL WITH PTFE is a multistep process using PTFE / Teflon that can be applied to aluminum, stainless steel, and various steel alloys. First, a nickel alloy coating that contains countless micropores is deposited on the metal surface. Then the surface is sealed using a controlled infusion of submicron particles of selected fluorocarbons. The resulting coating is then carefully heat treated to create a smooth, slippery surface.

EN with PTFE Teflon® provides:

  • Increased Hardness
  • Permanent Lubricity
  • Mold Release
  • Corrosion Resistance
  • Low Coefficient of Friction
  • Abrasion Resistance
  • Electrical Conductivity
  • Mil-C-26074 


coating properties

The coating process creates a dry-lubricated, non-stick surface that reduces friction of moving or sliding parts. It's ideal for cyrogentic applications down to -250°F. Coating thickness can vary from 0.0002 in. Minimum to 0.003 in. Maximum. Thickness is controlled to ±10%. Hardness of the coatings can range from Rockwell C 50 on aluminum to as high as Rockwell C 70 on steel.


Surface is smooth and slippery. In some cases, the static friction is decreased with increase in load. EN with PTFE Teflon eliminates "slip-stick" and undesireable vibration of higher break-away friction using PTFE / Teflon. Coefficient of friction: .18 - .12 static and dynamic respectively.
(NOTE: Surface finish or part to which coating is to be applied should have approximately an Ra 16 or better surface texture in order to achieve maximum abrasion and wear resistance coupled with lowest coefficient of friction.)
