Areas of application

  • Lubrication of highly stressed chains, joints or slideways at higher temperatures
  • For conveying systems running beneath radiated heat, in baking and drying lines in the foodstuffs industry
  • Dry lubrication at operating temperatures above 200°C
  • The synthetic oil content evaporates odorlessly without leaving residues, while the solid lubricant content are left behind to carry out dry lubrication

Advantages and benefits

  • Highly suitable as a high-temperature lubricant
  • Highly effective due to homogeneous distribution of the finest graphite throughout the oil
  • Versatile application as a liquid lubricant under high temperature conditions
  • Resistant to water, chemicals, fuels, lubricants, and hydraulic oils
  • NSF H1 registered
  • MOSH/MOAH-free (as per recipe)

Technical specifications

  • upper operating temperature: 150 °C (liquid lubrication)
  • density (at 20°C): 1.04 g/cm³
  • viscosity at (40°C): 170 mm²/s
  • four-ball test rig welding load: 2,800 N


For best results, clean the surfaces. Best way is to clean mechanically first and then with OKS 2610 or OKS 2611 universal cleaner. With a brush, drip oiler or by immersion or using a suitable automatic lubrication system, apply a sufficient quantity to the locations to be lubricated. If at all possible, avoid excess. The manufacturer´s instructions should be observed. Assess the lubrication frequency and quantity on basis of service conditions. Only mix with suitable lubricants.
