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.- Applications

- Physical and Grease Properties Note
- a) Not more than 3 rust spots visible to the naked eye. b) Brookfield viscometer at 10 rpm with spindle RV S95.
- Temperature Properties Note
- a) Cold storage avoids material separation and settling. If storing at room temperature, mix thoroughly to disperse filler before use.
