Liquid lignin-based dust suppressant and surface binder for roads, mining and industrial yards.
Sodium Lignosulfonate Dust Control Liquid is a water-soluble lignin-based liquid concentrate designed for dust suppression, surface binding and bulk material handling in high-dust industrial environments.
The liquid form allows fast dilution, easier spraying and more uniform distribution compared with dry powder addition.
After application and drying, the lignosulfonate binder helps capture fine dust particles and forms a cohesive surface film or crust.
Key Performance Functions
Dust Suppression
Binds loose surface particles and reduces airborne dust from roads, yards and stockpiles.
Surface Crusting
Forms a tacky film during drying and supports durable surface cohesion after curing.
Liquid Handling
Suitable for dilution, tank mixing and spraying systems without powder dissolution steps.
Particle Binding
Supports cohesion of dusty bulk solids and fine mineral particles in handling areas.

Recommended Application Areas
| Application Area | Typical Use | Customer Value |
|---|---|---|
| Unpaved Road Dust Control | Diluted spray treatment for rural roads, construction roads and service roads. | Reduces dust generation and improves surface binding. |
| Mining Haul Roads | Dust-control treatment for mine roads and material transport routes. | Improves visibility, operating environment and dust management. |
| Industrial Yards | Spray treatment for storage yards, loading areas and plant traffic routes. | Reduces fine dust movement and improves site cleanliness. |
| Stockpiles & Bulk Solids | Surface binding aid for dusty mineral, coal, coke or aggregate piles. | Helps reduce wind-blown dust and material loss. |
| Soil Surface Stabilization | Temporary surface stabilization after proper site testing. | Supports cohesion in selected soil and aggregate surfaces. |
Suggested Usage Guidance
| Application | Typical Starting Dosage / Use | Technical Note |
|---|---|---|
| Dilution before application | Typically dilute with water before spraying | Starting dilution should be adjusted from concentrate to site conditions. |
| Topical road treatment | 0.3 – 0.5 gallons prepared solution per square yard | Adjust by traffic volume, surface porosity, weather and desired service period. |
| Stockpile treatment | Apply evenly until surface is uniformly wetted | Avoid over-application that may cause runoff or handling issues. |
| Reapplication | Site-specific interval | Reapply after heavy rain, traffic abrasion or loss of surface crust. |
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.
