Areas of application

  • Long-term lubrication of dirt-sensitive sliding points under vibration stresses
  • Particularly suitable for lubricating chucks on tool machines
  • Broad range of uses at stress-loaded parts, also at contact with cooling lubricants
  • Lubrication of control and drive mechanisms
  • Can be used at filling, labelling and packaging machines

Advantages and benefits

  • Resistant to water, steam and aqueous cooling lubricants
  • Prevents frictional corrosion reliably
  • Highly effective due to optimum solid lubricant combination
  • Minimal consumption due to formation of highly effective lubricating films

Technical specifications

  • lower operating temperature: -45 °C
  • upper operating temperature: 110 °C
  • four-ball test rig welding load: 4,200 N
  • thread friction coefficient (μ total): 0.1 (screw ISO 4017 M10x55-8.8 black-oxide, nut ISO 4032 M10-10 black-oxide)


For optimum adhesion, clean contamination and other lubricants from thread and slide surfaces. Best way is to clean mechanically first and then with OKS 2610/OKS 2611 universal cleaner. Apply sufficient paste evenly to the functional surfaces with a brush, spatula, etc. The paste will also act as a sealant. Do not use paste instead of grease and mix only with suitable lubricants.
