Description

Tetraammonium Pyrophosphate is a water-soluble ammonium salt of pyrophosphoric acid. This compound serves as a highly effective source of pyrophosphate ions and ammonia in various industrial processes, valued for its buffering capacity and sequestering properties. It is primarily utilized in sectors such as industrial cleaning, water treatment, and as a component in specialty chemical formulations where controlled phosphate release is required.

Application

• Industrial Cleaners & Detergents: Acts as a builder and sequestrant to control water hardness and enhance cleaning efficacy in heavy-duty formulations.
• Water Treatment: Used as a corrosion inhibitor and scale control agent in cooling and boiler water systems.
• Textile Processing: Functions as a dispersing and sequestering agent in dyeing and scouring operations.
• Metal Surface Treatment: Employed in electroplating and metal cleaning solutions for surface conditioning.
• Ceramic & Clay Production: Serves as a deflocculant to control the viscosity of slips and slurries.
• Laboratory Reagent: Used in analytical chemistry and research as a buffering agent.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
