Frequently Asked Questions (FAQs)

What is Sulfamic acid?

Sulfamic acid also known as Amido Sulfonic acid, Sulfamidic acid or Sulphamic acid is a compound with the chemical formula H₃NSO₃. It is in the form of white, solid crystals or powder.

Why is Inhibited Sulfamic acid used as a preferred descaler over Inhibited Hydrochloric Acid?

The corrosion of Inhibited Sulfamic acid is less than Inhibited Hydrochloric Acid. It is often used as a replacement for Hydrochloric acid for the removal of rust.

What is the difference between Sulfamic acid and Sulfamic acid descalant?

Sulfamic acid is a chemical substance, which is used for various chemical processes and is chemically active compound without Corrosion Inhibitors.
Sulfamic acid Descalant is a mixture of Sulfamic acid with proprietary chemical additives, like Wetting agent and Corrosion Inhibitors.

What should be the strength of Sulfamic acid at the start of the descaling process?

The strength (pH) of Sulfamic acid at the start should be < 1.3

At what strength Sulfamic acid should be discarded after the descaling process?

It can be discarded at a pH of 4 as after this, no further reaction will occur.

How does Sulfamic acid work as a descalant?

Sulfamic acid Descalant works as descalant in removal of scale causing minerals like calcium and magnesium ions from water.

What are the uses of Sulfamic acid?

Sulfamic acid acts as Descaling agent, cleaning agent, pH regulator in swimming pools and water treatment.

What are the uses of inhibited Sulfamic acid?

It is used for removal of scales from water in cooling and heating systems e.g., Jackets, Coils. Boilers, Condensers, and Heat exchangers.

Can Sulfamic acid be used for removing rust?

Due to its acidic properties Sulfamic acid can be used as a rust remover as it aids in removing and dissolving rust from the surfaces.

Is Sulfamic acid safe to use on stainless steel?

It is safe to use on surfaces of stainless steel. Though, performing a spot test before applying it to the entire surface is preferred. Stainless steel is resistant to many acids, but prolonged exposure or using high concentrations of Sulfamic acid may cause etching or discoloration.

How do I clean boilers scales using Sulfamic Acid?

Refer to Sulfamic acid descaling process in Sulfamic acid descalant product section.

How to use Inhibited Sulfamic Acid for descaling?

Refer to Method of use in Sulfamic acid descalant product section.
