Hi, Ela. Sorry, but I do not quite understand the question yet. What do you wish the sulphamic acid to attack, and what do you wish it to not damage? Are you wanting to use it as a pickle for rusty steel, for example, and you want it to attack the rust but not attack the steel? (You would not use it unless you want it to corrode something). Thanks.

Q. I desire to make a formulation of the following product:

A descaler with sulfamic acid ⇦ on eBay or Amazon [affil link] , with corrosion inhibitors. The product will be used for the cleaning of scale deposits and rust in heat exchangers(interchanges), condensers, boilers and other equipments.
The product could be applied to all metals except the zinc and its alloys. For the zinc and its alloys what you could recommend us?

CHARACTERISTICS
Aspect: whitish powder
Content in sulfamic acid ⇦ on eBay or Amazon [affil link] > 95%
Solubility in the water: 20% at 15 °C
pH (10% of solution) : < 1

thanks
