High Temperature Greases


Castrol Braycote 2115 (previously called Molub-Alloy™ 2115) is a range of greases which are thermally stable, high temperature synthetic bearing lubricants. The products are formulated from an advanced synthetic fluid and thickened with a temperature stable non-soap base. Braycote 2115 contains lubricating solids for good wear protection and is designed to greatly extend service life and relubrication intervals in high temperature bearings, compared to conventional greases.


Primarily developed for extended service in oven conveyor bearings, Braycote 2115 is recommended for bearings operating in paint drying ovens, textile tentering frames, and similar applications where minimum reapplication and dripfree performance is required.

Braycote 2115 can be used in continuous service at 250°C / 482°F and may be exposed to intermittent temperatures up to 280ºC / 536ºF. Forced draft ventilation should be used at temperatures exceeding 250ºC / 482ºF Braycote 2115 can be applied manually or with automatic dispensing equipment.

  • Thermally and chemically stable – high resistance to oxidation at high temperatures extends relubrication intervals without undue risk of under lubrication, lubrication starvation or an increase in power draw
  • Virtually inert below 300ºC / 572ºF – resists the thickening and hardening that is typical of petroleum greases in high temperature service
  • Even at high temperatures (refer the Application section), Braycote 2115 is resistant to most non-fluorinated solvents and most chemicals, including strong acids, alkalis and oxidising agents
  • Low volatility – does not volatilise readily at high temperatures and/or when exposed to high vacuum

Braycote 2115 should not be mixed with other greases or oils.

Braycote 2115 has a very low order of toxicity at room temperature with no significant irritation to skin or eyes.

Above +250 °C / 482ºF, the use of forced draft ventilation is strongly recommended due to possible decomposition causing toxic and/or acidic vapours.

Due to Braycote 2115’s excellent resistance to ordinary cleaners and solvents, some industrial cleaners (fluorinated solvents) can provide a more effective clean-up solution. This product was previously called Molub-Alloy 2115. The name was changed in 2015.
