Description

Potassium Peroxymonosulfate is a powerful and versatile oxidizing agent, commercially significant for its stability and high active oxygen content. Its primary value lies in providing a potent yet controllable source of oxidation for a wide range of industrial and specialty chemical processes. This compound is essential for manufacturers and processors in sectors such as water treatment, electronics, pulp & paper, and organic synthesis, where reliable oxidation is critical.

Application

• Water Treatment & Disinfection: Used as a powerful non-chlorine oxidizer and biocide in swimming pools, spas, and industrial water systems to control algae, bacteria, and organic contaminants.
• Electronics Manufacturing: Employed in microelectronics for wafer cleaning and etching processes, as well as for formulating printed circuit board (PCB) etchants and cleaners.
• Pulp & Paper Bleaching: Acts as a bleaching agent for mechanical and chemical pulps, enhancing brightness while being more environmentally favorable than traditional chlorine-based agents.
• Organic Synthesis & Catalysis: Serves as a key oxidizing agent in the synthesis of fine chemicals, pharmaceuticals, and agrochemicals, often used in catalytic systems like Oxone®.
• Surface Treatment & Cleaning: Formulated into industrial and institutional cleaners, disinfectants, and denture cleaners for its stain-removing and sanitizing properties.
• Textile Processing: Utilized in textile bleaching and desizing processes to prepare fabrics for dyeing and finishing.

Quality Control

Our Potassium Peroxymonosulfate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active oxygen content, purity, and stability. Certificates of Analysis (COA) documenting key parameters are available for every shipment to ensure traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat, sparks, and open flame. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and decomposition. Incompatible with combustible materials, strong acids, reducing agents, and organic compounds. Store separately.
