What Is Supress-It
Suppress-it is a sustainable, environmentally-friendly, simple-to-apply, easy-to-maintain solution to the problem of dust suppression in the mining, tourism and agricultural sectors.
A brown coloured dispersion of bitumen particles in water containing a mildly alkaline anionic emulsifier.
Chemical Formula: Mixture of heavy hydrocarbons, high molecular weight organic compounds which are obtained from processing residue streams from the refining of petroleum crude oils.
Why Use Supress-It
Dust free haul roads provide lower cost per haul, better visibility, safer trips and extended tyre and equipment life which in turn leads to a reduction in overall expenditure and better service for users.
After application roads and other dust-bearing surfaces are dust and mud free and functional in all weather conditions.
How Suppress-IT Works
Creates high energy particle charges between bitumen & water molecules allowing for a fast stable break
Penetrates surface
Binds aggregate particles in soil
Inhibits ingress of water
Provides cohesion to dust particles
Retards erosion
