Bio-based dust suppression binder for unpaved roads, industrial yards and bulk material handling.
Calcium Lignosulfonate Dust Control Grade is a water-soluble lignin-based polymer used for dust suppression, surface binding and particle stabilization in industrial environments.
When applied with water, it forms a naturally tacky binder that captures dust particles and improves surface cohesion.
This grade is suited to unpaved roads, mining haul roads, industrial yards, stockpiles and dusty material handling operations where a chloride-free dust-control option is preferred.
Key Performance Functions
Dust Suppression
Binds loose surface particles and reduces airborne dust.
Surface Stabilization
Forms a tacky film and later a durable surface crust after drying.
Industrial Binding
Can assist pellet or compressed material binding in bulk-solid processes.
Chloride-Free Alternative
Offers a more environmentally friendly option compared with chloride-based treatments.

Recommended Application Areas
| Application Area | Typical Use | Customer Value |
|---|---|---|
| Unpaved Road Dust Control | Topical treatment for rural roads, mining haul roads and industrial roads. | Reduces dust generation and improves surface binding. |
| Industrial Yards | Dust suppression for yards, storage areas and material handling zones. | Improves working environment and reduces powder loss. |
| Mining & Bulk Materials | Binder for dusty minerals, powders and granular solids. | Supports particle cohesion and easier handling. |
| General Industrial Binder Use | Can assist dispersion or binding in selected industrial formulations. | Provides multi-functional lignosulfonate performance. |
Suggested Usage Guidance
| Application | Typical Starting Dosage / Use | Technical Note |
|---|---|---|
| Topical application | 0.3 – 0.5 gallons prepared solution per square yard | Adjust by soil type, traffic volume, climate and dust level. |
| Road treatment | Dilute in water before spraying | Apply evenly; repeat after heavy traffic or rainfall as needed. |
| Industrial yards | Site-specific rate required | Optimize concentration by surface material and operating conditions. |
| Bulk material binding | Pilot trial required | Confirm dosage by particle size, moisture and target strength. |
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.
