Product Features
Easy to dissolve in water, slightly acidic in aqueous solution, insoluble in ethanol.
It has good biological absorbability and can be used as a source of zinc in multiple fields.
Compared to heptahydrate zinc sulfate, monohydrate zinc sulfate has a higher zinc content and is suitable for applications that require high zinc content.

Functions and Applications

1, Zinc sulfate is used as trace element fertilizer to prevent crops from Zn deficiency and increase crop yields. Now more andmore farmers apply micronutrient fertilizers such as zinc sulfate.
2, It can be used as feed additive to supply trace element, prevent and cure some diseases because of zinc deficiency and prevent premature death. It also can increase appetite, control blood disorders and bone disease.
3, In industry field, zinc sulfate works as coagulator for man made fibril, and mordant in dyeing and printing industry.
