Product Overview & Quality

Product Name: Ammonium hydrogen difluoride (Ammonium bifluoride)
Brand: Kemaus (Product Code: KA-853)
Grade: Laboratory Grade (Lab Grade) with a purity of 95 percent or higher. Produced under Kemaus strict quality control to guarantee consistent chemical behavior. Suitable for general laboratory experiments, metallurgical research, and specific industrial surface treatments.
Physical Properties: Colorless crystals or white crystalline flakes with a faint, pungent odor.
Critical Chemical Nature: Yields a strongly acidic aqueous solution upon dissolution and chemically attacks glass matrices (glass etching). Contact with glass or ceramic laboratory equipment must be strictly avoided.
Key Use: Widely utilized as a specialized reagent in metallurgy for pickling, cleaning, and etching metal surfaces (such as aluminum and stainless steel). Heavily applied in materials science laboratories for chemical glass-etching or frosting processes. Also serves as an intermediate catalyst in unique organic chemical synthesis.

Safety & Hazards (Critical)

Classification: Toxic if swallowed. Causes severe skin burns and serious, permanent eye damage.
Health Risks: Ingestion leads to severe internal chemical burns and acute systemic toxicity. Direct skin or eye contact results in deep, painful tissue destruction. Inhalation of its dust or volatile fumes causes severe respiratory tract damage.
First Aid Measures: Immediately flush affected skin or eyes with plenty of flowing water for at least 15 to 30 minutes. (Apply calcium gluconate gel to the skin if available after washing). Seek urgent medical attention immediately.

Handling & Storage

Storage: Highly Hygroscopic and Glass-Corrosive. Must be stored exclusively in the original, tightly sealed Kemaus plastic container (Never transfer into a glass bottle). Keep in a cool, dry, and well-ventilated dedicated chemical area at room temperature (below 30 degrees Celsius). Keep strictly away from strong acids, strong bases, and moisture.
Precautions: Comprehensive PPE is mandatory, including chemical-resistant gloves, safety goggles, a protective coat, and a dedicated particulate respirator. Handle strictly within a functioning fume hood to avoid inhaling airborne chemical dust or vapors.
