Industrial Applications
Construction Industry
- Plasticising agent: To improve workability in concrete while reducing water content for enhanced strength and durability.
- Water Reducer: To reduce the water-to-cement ratio, improving the compressive strength and longevity of concrete structures.
- Binding Agent: To improve cohesion in cement mixtures, enhancing overall workability and reducing the chance of segregation in concrete.
Ceramics Industry
- Dispersing Agent: To disperse fine particles and improve the consistency of the ceramic slurry
Agriculture
- Soil Conditioner: To enhance soil structure and water retention, improving nutrient absorption and reducing soil erosion.
- Binding agent: To improve pellet quality and reduce dust in palletised animal feed.
Textile Industry
- Dispersant: To ensure consistent colour application on fabrics
Mining Industry
- Dust suppressant: To reduce airborne particulates in mining operations, improving air quality and worker safety.
Other Industries
- Pellet Binder: Used as a binder in various industrial applications, including carbon black, and metallurgical processes.
- Adhesive Additive: To enhance bonding strength and flexibility in the production of adhesives
