An organic lignosulphonate based road binder offering superior dust control results

HydroTac is a specially formulated biodegradable binder that can be used on haul roads, access roads and other exposed surfaces as a spray-on dust control treatment.

Totally organic, it has no corrosive chloride compounds and is environmentally friendly and readily biodegradable.

Working as a hygroscopic crusting agent, this lignosulphonate based dust control product helps mines to reduce water bowser usage for dust control purposes and has been shown to reduce water cart operating hours by up to 80%, reducing road maintenance, regular replenishment of surface wearing course material and the likelihood of a vehicle losing control as a result of over-watering.

Product Overview

Lignosulphonates are by-products from sulphite paper and timber making processes in which sulfonated lignin, a polymer built up of phenyl propane subunits, is dispersed in an aqueous solution. The binding properties of lignin are enhanced by the addition of sugars which helps bind surface road and dust particles together. Water evaporates from the lignosulphonate as it dries and the dust particles are trapped by the high-viscosity, naturally sticky material.

  • Safer roads due to improved visibility.

  • Operational cost savings and efficiencies 75% and a reduction in road maintenance

  • Reduced need for graders and maintenance equipment

  • Safer haulage conditions

How to apply HydroTac

HydroTac is a versatile product that is easy to handle and apply without any specialised equipment required. In order to suppress dust on roads and other surfaces, HydroTac can be applied via a series of light dilutions using water bowsers.

Once applied, the need for reapplication is minimal. Mines which typically rely on continuously spraying untreated water on haul road networks in order to control dust will dramatically reduce water usage and water cart hours by switching to HydroTac.

HydroTac is conveniently delivered in a concentrated liquid form ready to use. It is typically diluted in a water bowser at a concentration of 1.5% up to 20% depending on the specific requirement.
