3. Applications
Industrial Grade:
Oilfield Operations: Used in drilling, completion, and workover fluids as a high-density brine (up to 1.58 g/cm3), providing superior lubricity and corrosion inhibition.
Deicing Agent: Eco-friendly alternative to chloride-based salts; low corrosion on metals and concrete.
Leather Processing: Serves as a tanning and pH buffering agent.
Textile Industry: Used in dyeing and printing processes to stabilize dyes.
Food Grade:
Food Preservative: Inhibits microbial growth and extends shelf life of certain food products.
Nutritional Additive: Potassium source in mineral supplements.
pH Regulator: Maintains stability in processed foods and beverages.
4. Advantages
Eco-friendly: Biodegradable and less harmful to soil and water compared to traditional salts.
High Solubility: Enables preparation of high-density, low-viscosity brines.
Corrosion Inhibition: Protects steel and other metals in harsh environments.
Low Toxicity: Safe for controlled applications in food and feed (food grade).
5. Packaging & Storage
Packaging:
Industrial Grade: 25 kg / 50 kg PP woven bags with inner liner, jumbo bags, or IBC drums (for liquid).
Food Grade: 25 kg food-grade PE-lined bags.
Storage: Store in a cool, dry, and well-ventilated place. Keep container tightly closed to avoid moisture absorption.
Shelf Life: 24 months under proper storage conditions.
6. Safety & Handling
Avoid contact with skin and eyes.
Use appropriate personal protective equipment (PPE) such as gloves and goggles during handling.
Refer to SDS for detailed safety information.
