Flake aluminium powder coated with fatty acid so it handles safely and stays stable in aqueous media of different pH. Used as a sensitiser and energy source in slurry and emulsion explosives. Grades differ in water coverage area and fatty acid content.
Used in
- Slurry and emulsion explosives for mining
- Defence and ordnance applications
