kluberpaste hel 46-450

High-temperature screw paste.

Klüberpaste HEL 46-450 is a black hot screw paste for high-alloy steels. It contains fully synthetic polyalkylene glycol and ester base oils and a combination of inorganic solid lubricants.

Klüberpaste HEL 46-450 is suitable for a temperature range between -40 °C and 1000 °C. In the normal temperature range (i.e. below 200 °C) it shows good anticorrosion behaviour and good water resistance. Above 200 °C it acts as a dry lubricant.

  • Screw paste for conventional and high-alloy steels (Cr-Ni steels) up to 1000 °C.
  • Lubricating and assembly paste for connections in hot air ducts (e.g. automotive exhaust systems). For connecting elements in turbochargers and compressors.
  • It is important to clean and degrease the contact surfaces thoroughly before applying Klüberpaste HEL 46-450.
  • A thin layer of paste is then applied by brush, leather cloth or plastic sponge.
  • Klüberpaste HEL 46-450 spreads easily over the entire surface and thus prevents excess lubrication.
  • Close container immediately after use in order to prevent contamination.
  • The friction values indicated on page 2 in the Section Product Data were determined with two different materials. Other materials/surfaces have to be checked accordingly.
  • Reliable screw connection ensured by constant and sufficient preload force
  • Easy release also after long time at high temperature
  • Approved in Ford tox. No. 138624
