High Purity 99.5% Industrial Descaling Agent Sulfamic Acid Amidosulfonic Acid Powder NH₂SO₃H

Sulfamic Acid (NH₂SO₃H), also known as amidosulfonic acid, is a high-purity, solid inorganic acid with a 99.5% assay. This white crystalline powder is non-volatile, non-hygroscopic, and odorless, making it the preferred acidic cleaning and descaling agent for both industrial and domestic applications. Its unique combination of strong acidity, excellent water solubility, and reduced metal corrosivity compared to hydrochloric or sulfuric acid makes it exceptionally safe and effective. Beyond industrial cleaning, sulfamic acid serves as an essential intermediate in the synthesis of dyes, herbicides, artificial sweeteners, and other fine chemicals.

• High Purity Standard: Minimum 99.5% assay ensures consistent cleaning performance and reliable reaction stoichiometry
• Solid and Stable Form: White crystalline powder that is non-volatile and free of pungent fumes
• Excellent Descaling Performance: Rapidly dissolves calcium carbonate, magnesium hydroxide, rust, and other mineral scales
• Reduced Metal Corrosion Risk: No free chloride ions, greatly lowering risk of stress corrosion cracking and pitting
• Multi-Purpose Functionality: Serves as sulfonating agent, dye intermediate, and chlorine stabilizer

• Industrial Descaling and Cleaning: Removes hard water scale, milk stone, and rust from boilers, heat exchangers, cooling towers, and pipelines
• Metal Finishing and Electroplating: Pickling and brightening copper, brass, and mild steel prior to plating
• Dyestuff and Chemical Intermediate: Sulfonation reagent in production of dyes, pigments, and artificial sweeteners
• Pulp and Paper Industry: Bleaching catalyst that prevents degradation of cellulose fibers
• Chlorine Stabilization: Extends chlorine disinfection lifetime in swimming pools and cooling water systems

• Safer Alternative to Hydrochloric Acid: Solid, non-fuming acid eliminates handling and ventilation risks
• Equipment Longevity: Virtually chloride-free composition prevents stress corrosion cracking
