Sulfamic acid is a white powder. Under normal temperature, as long as it is dry and does not contact with water, solid Sulfamic acid is not hygroscopic and is relatively stable. The aqueous solution of Sulfamic acid has the same strong acidity as hydrochloric acid, sulfuric acid, etc., so it is also called solid sulfuric acid. It is nonvolatile, odorless and has little toxicity to human body.


Sulfamic acid is widely used in a variety of industrial equipment and civil cleaning agents for metal and ceramic manufacturing, petroleum processing agents and cleaning agents, electroplating industrial agents, electrochemical polishing agents, asphalt emulsifiers, etchants, sulfonation agents for dye medicine and pigment industries, dyeing agents, high-efficiency bleaching agents, fibers, flame retardants for paper, softeners, resin crosslinking accelerators, softeners for paper and textiles, herbicides, anti drying agents In Analytical chemistry, it is used as the reference reagent for acid titration and standard analytical reagent in various fields.


Store in a cool, ventilated, and dry place. The packaging should be sealed and protected from moisture. During transportation, it is necessary to prevent rain and sunlight exposure. Wear Gas mask and gloves when disposing of escaping materials, sweep them with sand or wash them with water. When a fire occurs, water, sand, and fire extinguishers can be used to extinguish it.
