Aluminium paste for assembling screw and bolt threaded connections that are subjected to high temperatures and corrosive influences.

Areas of application

  • Assembly lubrication of machine parts, screw connections, fittings, flange and plug-in connections, guides, sliding and sealing surfaces of ovens, boilers, burners, motors, engines subject to high-temperature conditions
  • Separating paste

Advantages and benefits

  • Excellently suited for preventing seizing and burning together
  • Highly effective due to outstanding separating action and pressure absorption
  • Good protection against ingress of splashing and condensed water
  • Free of heavy metal compounds
  • Good corrosion protection
  • Excellent water resistance
  • Wide operating temperature range
  • Optimum ratio of screw tightening torque to achievable pre-tension

For best adhesion, clean contamination and other lubricants from thread and slide surfaces. Best way is to clean mechanically first (for example, with a wire brush) and then with OKS 2610/OKS 2611 universal cleaning agent. Evenly spray a sufficient amount of OKS 2351 onto the head or nut contact surface and thread. Do not use paste instead of grease and mix only with suitable lubricants.
