Armite MIL907
  • Anti-Corrosion Quality – MIL907 not only has a high corrosion resistance but also prevents oxidation and corrosion in the materials to which it is applied. This quality makes it a standard for all-around use in chemical plants and refineries.
  • Anti-Seize and High Temperature Qualities – The compound remains as an effective anti-seize compound, even to the fusing or melting point of the surrounding metals. The hydrocarbon vehicle volatilizes out between 600° to 700° leaving only the pure lead, which becomes liquid at about the same temperature. On cooling, the lead solidifies as a fine metallic ash and still retains its lubricating and sealing qualities. Recommended uses include steam and gas turbines, refinery units, boilers, railroads and aircraft.
  • Low Temperature Use – The compound forms an effective seal for equipment handling liquid nitrogen at -350°F. It is recommended for pipe sealing applications at temperatures of -100°F.
  • High Pressure Applications – Increasing pressure causes lead particles to pack more closely, strengthening the seal. MIL907 has been tested up to 100,000 PSI hydraulic fluid lines.
  • Anti-Seize (Metal to Metal) – MIL907 prevents a corrosion weld between metal-to-metal surfaces. This feature is important from the standpoint of maintenance of heavy industrial equipment.
  • Anti-Galling or Anti-Freezing – The compound forms a thin, pure-lead coat on metal while filling all voids and smoothing the surface. Friction is greatly reduced and less torque is needed for assembly and disassembly. Because the joined metals are isolated from moisture and oxygen, deterioration by galvanic action is impossible. In the same manner, hydrogen embrittlement is prevented.
  • MIL907 is particularly useful for materials that gall easily, such as aluminum and stainless steel.
  • Lubricating Qualities – Although not recommended as a bearing lubricant, except for very loose journal bearings (its plating action will freeze close tolerance bearings), MIL907 is valuable as a lubricant in many tapping, machining, and metal forming jobs.
