What is Sulfamic acid?
It is a dry, non-volatile, non-hygroscopic, odorless, white crystalline, stable acid .It is moderately soluble in water and forms strongly acidic aqueous solution that is comparable in acidity to the common strong mineral acids but it may be easily handled and stored in the dry form. At room temperature ,dilute aqueous sulfamic acid solution is stable for a long time but rapid hydrolysis occurs at elevated temperatures .Its solution is less corrosive toward metals than other mineral acid. Because of advantages such as handling ease, solubility and low corrosiveness, sulfamic acid is used for many diversified applications.
