Sulfamic Acid
Sulfamic Acid, also known as Amidosulfonic Acid / Sulphamic Acid, is a water-soluble inorganic acid widely used for industrial descaling, acid cleaning, boiler cleaning, heat exchanger cleaning, cooling-system maintenance and metal-surface treatment. Its chemical formula is NH₂SO₃H and its CAS Number is 5329-14-6. It is normally supplied as a white crystalline powder or crystals.
Sulphamic Acid is an odorless, white, crystalline (sand-like) solid. It is used in cleaning metal and ceramics, dye manufacturing, for stabilizing Chlorine in swimming pools, in electroplating, and as a bleaching agent.
