Description

Sulfuric Acid, Zinc Salt (1:1), Hexahydrate is the hydrated zinc salt of sulfuric acid, commonly known as zinc sulfate heptahydrate. This high-purity inorganic compound is a critical source of bioavailable zinc for a wide range of industrial and nutritional applications. It is essential for manufacturers in the agricultural, pharmaceutical, and chemical synthesis sectors requiring a reliable and consistent zinc supplement.

Application

• Agricultural Micronutrient: A primary ingredient in fertilizers and animal feed premixes to prevent and correct zinc deficiencies in crops and livestock.
• Pharmaceutical & Nutraceutical Manufacturing: Used as a zinc source in vitamin and mineral supplements, as well as in certain topical medicinal formulations.
• Industrial Chemical Synthesis: Serves as a precursor and catalyst in the production of other zinc compounds, dyes, and pigments.
• Water Treatment & Corrosion Inhibition: Employed in cooling water systems and as a component in corrosion-resistant surface treatments.
• Electroplating & Galvanizing: Used in electrolyte solutions for zinc electroplating processes to provide protective coatings on metals.
• Textile Processing: Acts as a mordant in dyeing processes and in the production of rayon and other synthetic fibers.
