Hammersley Dustat is a plant based dust control concentrate for water carts on haul roads, quarries and stockpiles, in 20L Drum, 205L and 1000L IBC.
What it does
Dustat goes into the water you already spray for dust. Low surface tension lets it wet soil quickly, then it binds fine particles into heavier clumps. Hammersley calls it strongly hygroscopic, so treated ground holds moisture, and repeat passes compact the surface. The 20L label claims lower water use and less spray time. The SDS lists calcium lignosulfonate at 20 to 50 per cent.
Where to use it
- Haul roads and industrial access roads, above ground and underground
- Road works, verges and embankments
- Gravel and aggregate stockpiles, and fly ash containment areas
It sits in our Dust Suppression range.
How to use
- Mix Dustat into the water cart or spray tank.
- Pick a rate from the table and adjust for weather and the local aggregate.
- For a hard base, spray at 1:5 twice daily for 3 days.
