We are chiefly engaged in manufacturing and supplying the best quality Zinc Sulphate Heptahyrate. Required for curing the mineral deficiency in crops, our Zinc Sulphate Heptahyrate is the best choice available in the markets. The Zinc Sulphate Heptahyrate that we provide is especially formulated by reacting zinc with light aqueous sulfuric acid. Available in varied packing options, our quality-tested Zinc Sulphate Heptahyrate is very affordable.
Zinc Sulphate Application
- fertilizer (for soils)
- Pigment industry
- Chemical industry
- Agriculture industry
- Textile and leather industry
- The hydrates, especially the Heptahydrate, are the primary forms used commercially. The main application is as a coagulant in the production of rayon
- It is also a precursor to the pigment lithopone. Zinc sulfate is used to supply zinc in animal feeds, fertilizers, and agricultural sprays. Zinc sulfate, like many zinc compounds, can be used to control moss growth on roofs, health care industries like oral care
- It is used as in electrolytes for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic
