Bio-based dust suppressant and surface binder for roads, mining yards and industrial bulk material areas.
Sodium Lignosulfonate Dust Control Grade Powder is a lignin-based dust suppressant for unpaved roads, haul roads, industrial yards and bulk material areas that need better surface cohesion and lower airborne fines.
After dilution and spraying, this grade forms a tacky organic binder film that captures fines and helps build a more durable crust on dusty surfaces.
It is a useful chloride-free option for operations that want bio-based dust control in mining roads, stockyards, plant roads and material handling zones.
Key Performance Functions
Surface Binding
Binds loose particulate matter after water evaporation and helps create surface crust.
Dust Reduction
Reduces airborne fines from traffic, wind and material handling.
Road Stabilization
Supports maintenance control on unpaved roads and industrial yards.
Bulk Material Aid
Can assist cohesion of selected fine powders and aggregates.

Recommended Application Areas
| Application Area | Typical Use | Customer Value |
|---|---|---|
| Unpaved Roads | Diluted surface treatment for roads with frequent vehicle movement. | Reduces dust, improves surface cohesion and extends maintenance interval. |
| Mining Haul Roads | Dust suppressant for mine roads and loading areas. | Improves visibility, worker comfort and particulate control. |
| Industrial Yards | Surface binder for stockyards, plant roads and loading zones. | Reduces fine powder loss and facility dust levels. |
| Bulk Material Handling | Binder support for selected fine powders and aggregates. | Improves cohesion and reduces handling dust. |
Suggested Usage Guidance
| Application | Typical Starting Dosage / Use | Technical Note |
|---|---|---|
| Topical application | 0.3 – 0.5 gallons prepared solution per sq yd | Dilution depends on soil, traffic and climate. |
| Initial treatment | Higher concentration recommended | Apply evenly and allow surface curing. |
| Maintenance treatment | Lower concentration possible | Reapply based on rainfall, traffic and dust condition. |
| Pilot test | Recommended before full application | Confirm soil compatibility and target performance. |
Dosage and application method should be verified by laboratory or pilot testing. Performance depends on raw materials, process conditions, temperature, moisture, mixing time and target technical results.

Buyer Questions
How does sodium lignosulfonate control dust?
It works by binding fine particles at the surface so wind and traffic release fewer airborne fines. After drying, it helps form a cohesive surface layer.
Where is this grade commonly used?
Typical uses include haul roads, plant roads, stockyards, open yards and other bulk material handling areas with recurring dust problems.
Is this a chloride-free dust suppressant?
Yes. It is commonly selected when customers want a bio-based dust control option without chloride salts.
