Sulfamic Acid is a non-hygroscopic and stable white crystalline solid. Sulfamic Acid is a super efficient scale remover. It is used to clean many household appliances and industrial equipment.


Sulfamic Acid is used as an acid cleaner and is commonly used in ceramics and metals. Sulfamic Acid is a safe and potent acid suitable for descaling applications and pickling.

Sulfamic Acid known as sulfuric acid, is a non-hygroscopic and stable white crystalline solid. Soluble in formamide and water, slightly soluble in concentrated sulfuric acid, methanol, acetone and ether. Sulfamic Acid as a detergent is commercially produced from fuming sulfuric acid and urea and is a strong inorganic acid. Sulfamic Acid stabilizes longer at room temperature with dilute aqueous solution. However, rapid hydrolysis occurs at high temperatures. Sulfamic Acid is considered less corrosive to metals than other strong acids such as hydrochloric acid. Because sulfamic acid retains the capacity to dissolve scale, it is considered to remove cooling towers, boilers, coils and condensers.


The use of Sulfamic Acid


Because Sulfamic Acid is an ultra-efficient scale remover, it is used to clean many household appliances and industrial equipment. It is used for cleaning heat exchangers, boilers, condensers, descaling toilets, jackets and coils, weathering other mineral deposits, removing excess cement slurry from ceramic tiles, etc. It helps remove protein deposits, hard scale, beer and milk stone, copper corrosion and mild rust. Some other uses of sulfamic acid are listed below.


  • Scale remover, rust remover and cleaning agent.
  • Scale remover and cleaning agent for dairy equipment, such as milk evaporator, milking machine piping.
  • Scale removers and cleaners for brewery equipment such as vats, pipes, etc.
  • Catalysts for esterification processes.
  • Used in dye and pigment manufacturing
  • Used as a herbicide.
  • Effective against feet and mouth.
  • Used as an ingredient in denture tablets.
  • Composition of fire extinguishing agent.
  • Urea-formaldehyde resin coagulant
  • Synthesis of nitrous oxide by reaction with nitric acid.
  • Chloride stabilizers in the pulp and paper industry.
