Sulphamic Acid (S.R. Grade)

Sulphamic Acid for Descaling and Cleaning

Sulphamic Acid is a dry, white crystalline acid that dissolves limescale quickly. Sulfamic acid is strong in solution yet supplied as a stable, non-fuming solid. As a result, it is safer to transport and store than liquid mineral acids.

We stock S.R. grade Sulphamic Acid exported by Palvi Industries Limited, made in India and packed in 25 kg bags with a two-year shelf life. Wisdo Merchants Chemical Division delivers it across Kenya and East Africa from Industrial Area, Nairobi.

Features and Benefits of Sulphamic Acid

• Fast descaling: Dissolves calcium carbonate scale effectively.
• Solid and non-fuming: Easier to handle than hydrochloric acid.
• Less corrosive to metals: Gentler on many metals than hydrochloric acid, especially when inhibited.
• Stable: Keeps well as a dry powder.

Applications of Sulphamic Acid

Descaling Equipment

Maintenance teams circulate sulphamic acid solutions through boilers, heat exchangers, cooling towers, coffee machines and water heaters to remove scale. Afterwards, they rinse and neutralise the system. Browse our cleaning and disinfection chemicals.

Cleaning Products

Formulators use it in toilet cleaners, tile cleaners and dairy equipment descalers. For food-safe or milder descaling, compare it with our anhydrous fruit acid.

Industrial Processes

Dye makers use it to remove excess nitrite. Paper mills use it to stabilise bleaching, and metal finishers use it in some plating baths. See our metal treatment chemicals.

Safety and Handling

The bag shows the irritant symbol. Handle it with care, as the label advises.

• Irritant: It causes skin and serious eye irritation. Use protective gloves and goggles while handling.
• First aid: Avoid eye and skin contact, and wash immediately with water in case of contact.
• Do not mix: Never mix it with chlorine bleach or other cleaners.
• Environment: It is harmful to aquatic life. Neutralise solutions before disposal.

Always read the Safety Data Sheet before use.

Storage and Shelf Life

Store bags in a cool, dry place, as the label instructs. Keep them sealed and away from alkalis, chlorine products and strong oxidisers. Use it within two years of manufacture.

Frequently Asked Questions

Is sulphamic acid safer than hydrochloric acid?
It is a dry solid that does not fume, so it is easier to handle. However, it is still an irritant acid and needs protective equipment.

Can I use it on stainless steel?
Generally yes, at suitable concentrations. Test first and rinse thoroughly after descaling.
