Fine Powder Zinc Sulphate Monohydrate (33% & 35.5%)
Fine powder zinc sulphate monohydrate is the finely milled form of ZnSO4.H2O containing 33% or 35.5% zinc. Its high surface area dissolves quickly, which suits premix manufacturing, fertigation stock solutions and any process where the material must go into solution fast.
The fine powder grade is preferred by micronutrient formulators and premix manufacturers who need a fast-dissolving, uniformly milled zinc source. Because fine powder can create dust and segregate in a dry blend, it is best kept for mixing and dissolving tasks. The 33% and 35.5% assay tables are published below.
