Product Notes

Packing of Sulphamic acid ( NH2SO3H or H3NO3S )

Sulphamic Acid is available in H.D.P.E. bags of net 25 and 50 Kgs. Material. Sample packets of 100-200 gms. are supplied on request. 

Advantages of using Sulphamic Acid

  • Sulphamic Acid has very high shelf life.
  • Sulphamic acid do not require storage/handing arrangement hence no adulteration possible.
  • Sulphamic acid has very high effectivity of the descaling.
  • Complete cleaning can be chemically achieved by Sulphamic acid and does not require post descaling manual cleaning.
  • Sulphamic acid is safe acid, packed in 50 kgs HDPE bags and has no handling hazards.
  • No storage tanks / system required for dosing.
  • The solid can be directly charged to system eliminating the cost of system reduces the leave of scaling solids and acts as anti - descalant.
  • Accidental excess dosing does not affect the metal of the circulating system but it acts to remove the deposited scale from the system.
  • It is recommended to does into the cooling water for descaling the condenser on running plant.


   Sulfamic Acid is used for descaling.

•    Sulfamic Acid is very efficient descaling agent and is widely used for cleaning a variety of industrial equipments, especially boilers, condensers, cooling tower and pipelines.

•    In paper & pulp Industry, Sulfamic Acid is used to prevent pulp degradation due to temperature conditions existing at the chlorination and hydrochloride stage. Sulfamic Acid also permits bleaching at higher temperature and lowers pH without loss of strength of fiber.

•    Sulfamic acid is used in manufacturing of Dyes, Pigments and in the dyeing of leather.

•    Sulfamic Acid removes excess of nitrides used in the diazotization reactions in the manufacturing of dye stuffs and pigments. Nitrides, if present, in process water of effluents can also be removed by using Sulfamic Acid.

•    In Chlorine Stabilization, Chlorine gas in water form HOCL which reacts with Sulfamic Acid form N-Chloro-Sulphamic Acid to N-ChloroSufamic Acid more stable and yet has active chlorine, Because of this, Sulfamic Acid is used for stabilizing chlorine in swimming pools and cooling towers.

•    In Electroplating and Electro-refining, Metal sulphamate electrolytes values for their high solubility cadmium, cobalt nickle, lead silver and radium sulphamte deposits are bright and dense. Lead sulphamate is used in refining lead when a high quality is desired.

•    In Solutation and Sulphamation, Sulfamic Acid is used for sulphation and sulphamation of many organic compounds. Sulphation of alkyl pheno-ethylen oxide condensation products for detergents and sulphation of ethoxylated phenol-formaldehyde resins is preferable with Sulfamic Acid. Stronger agents cause unwanted ring sulphomation.

•    In the Plastic industry, Sulfamic Acid finds application in the plastic wherever a curing agent is required which does not have the disadvantage of inorganic acids and which acts faster than organic acids.

Other Applications

•    Sulfamic Acid is preferred greatly to Hydrochloric Acid in household usage for its intrinsic safety value.

•    Sulfamic Acid is used in the design of many types of therapeutic agents such as Antibiotics, Nucleoside/nucleotide Human immunodeficiency virus (HIV) reverse transcriptase inhibitors, HIV protease inhibitors (PIs), anti-cancer drugs (steroid sulfatase and carbonic anhydrase inhibitors), anti-epileptic drugs, and weight loss drugs.

•    Sulfamic Acid is used as an acidic cleaning agent for metals and ceramics.

•    It is used frequently for removing rust and limescale.

•    Sulfamic Acid is used in the industrial cleaning of dairy and brew-house equipment.

•    It is used as a catalyst for esterification process.

•    Sulfamic Acid is used in Dye and pigment manufacturing.

•    Sulfamic Acid is used as an Ingredient in Denture Tablets, Fire Extinguishing Media.

•    Sulfamic Acid is used in Pulp and paper industry as a chloride stabilizer.
