Applications & Uses
- Applications
- Application Instructions
To apply the grease:
- Wear protective gloves.
- Clean and dry the surface being lubricated with a lint-free cloth or brush and a zero-residue cleaning solvent, such as MG 824 Isopropyl Alcohol.
- Apply a thin, even layer of grease using a spatula or other appropriate applicator.
Attention!
Carbon grease is messy and transfers easily. Be careful not to spread it beyond the intended area.- Application

- Grease Properties Note
- a) Thermal cycling of ten cycles from -40 to 121 °C [-40 to 250 °F]. b) Bearing dried at 77 °C [171 °F]. c) Aluminum 2024 coupons with 254 μm [10 mil] film thickness and >550 h exposure to 5% salt spray
- Physical and Synthetic Oil Properties Note
- Values based on synthetic oil component only
- a) Brookfield viscometer at 12 rpm with spindle RV S94.
- b) High oil viscosity index of more than 100 indicates a small oil viscosity change with temperature.
- c) Temperature at which the oil will continue to burn for at least 5 s after ignition with an open flame.
- d) Cleveland open cup method.
- Temperature Properties Note
- a) Cold storage avoids material separation and settling. If storing at room temperature, mix thoroughly to disperse filler before use.
