Applications

1. Wood Preservation & Termite Control A proven boron-based wood preservative for construction timber, lumber and wood products. Penetrates deeply into wood to protect against termites, wood-boring insects and fungal decay, delivering long-term protection with low environmental impact.

2. Fire Retardants & Insulation An effective fire retardant for cellulose insulation, wood and textile treatments. Reduces flammability and slows flame spread, meeting safety standards in residential and commercial building applications.

3. Boron Micronutrient Fertilizer A highly water-soluble boron source for foliar sprays, fertigation and soil application. Corrects boron deficiency in fruit, vegetable and field crops, supporting flowering, fruit set and overall crop quality.

4. Mold Prevention & Cleaning An efficient mold and mildew prevention agent for building materials, walls and industrial surfaces. Its high solubility enables easy application and durable protection in humid environments.

5. Glass, Ceramics & Enamel A versatile boron source for glass fiber, ceramic glazes and enamel formulations. Improves melting behavior, thermal stability and product performance in glass and ceramic manufacturing.

6. Corrosion Inhibition & Specialty Applications Provides corrosion inhibition in metal treatment and industrial fluid applications. Consistent quality and high solubility support reliable performance across diverse specialty uses.
