This is one of 2 grades in our Sulphamic Acid — Descalant and Technical Grade. Compare all 2 grades →
Overview
Sulphamic Acid (Technical, 99.5%) is the high-purity grade, with at least 99.5% purity, sulphate (acidity as SO₄) at 0.15% max, free moisture at 0.20% max and iron at 50 ppm max. The low iron and sulphate make it suitable for electroplating pre-treatment, dye and pigment manufacture and as a bleach stabiliser, as well as for high-purity descaling. For routine descaling, the descalant grade is more economical. Supplied from Chennai by Suraj Chemicals.
