Klüber Klüberpaste HEL 46-450
High-temperature screw paste
Application Klüber Klüberpaste HEL 46-450
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. The test was performed acc. to VW-TL 52112 Bolt: DIN 931-2; Material:1.4989; Nut, material: 1.4923. The nuts were preloaded with 70 Nm and stored at 750 °C for 100 hours. After this period a low release torque was measured.
Performance, Features & Benefits of Klüber Klüberpaste HEL 46-450 are:
- Reliable screw connection ensured by constant and sufficient preload force
- Easy release also after long time at high temperature
- Approved in acc. with VW-TL 52112 and Ford tox. No. 138624

Product Description Klüber Klüberpaste HEL 46-450
Klüberpaste HEL 46-450 is a black hot screw paste for highalloy 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.

Application notes
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.
