Castrol Molub-Alloy 2115 grease is a thermally stable high-temperature synthetic bearing lubricant. It is formulated from an advanced synthetic fluid and thickened with a temperature stable non-soap base. Molub-Alloy 2115 includes a blend of performance additives and Molub-Alloy lubricating solids for exceptional wear protection and is designed to greatly extend service life and relubrication intervals in high temperature bearings. Advantages:
Thermally and chemically stable – unparalleled resistance to oxidation at high temperatures therefore extending relubrication intervals without undue risk of under lubrication, lubrication starvation, or an increase in power draw.
Virtually inert below 300°C/575°F – resists the thickening and hardening that is typical of petroleum greases in high-temperature service.
Even at high temperatures, Molub-Alloy 2115 is resistant to organic solvents and most chemicals, including strong acids, alkalis, and oxidizing agents.
Low volatility – does not volatilize readily at high temperatures and/or when exposed to high vacuum.
Formulated to address environmental concerns – it is free of lead, chlorinated solvents and barium.
Additional Information: Molub-Alloy 2115 should not be mixed with other greases or oils. In case of doubt please consult your local Technical Services.
Molub-Alloy 2115 has a very low order of toxicity at room temperature with no significant irritation to skin or eyes.
At 200°C/392°F, small quantities of toxic fumes are generated. The use of 2115 above 200°C is not recommended without the use of forced draft ventilation.
At 300°C/572°F, 2115 decomposition begins to accelerate, and small amounts of highly toxic, potentially acidic vapors are formed. Positive draft ventilation to the atmosphere is essential.
Clean-up may be difficult because of the excellent resistance to ordinary cleaners and solvents. However, there are some industrial cleaners (fluorinated solvents) which can be used effectively.
Applications: Primarily developed for extended service in oven conveyor bearings, Molub-Alloy 2115 is recommended for bearings operating in paint drying ovens, textile tentering frames, and similar applications where minimum reapplication and drip-free performance is required.
Molub-Alloy 2115 can be used in continuous service at 250°C/482°F and may be exposed to intermittent temperatures up to 280°C/536°F. Forced draft ventilation should be used at temperatures exceeding 200°C.
Molub-Alloy 2115 can be applied manually or with automatic dispensing equipment.
