Application Scope
1、Mordant: Cotton fiber treatment dosage 3%-5%, color fastness increased by 20%.
2、Nutritional fortifier: Infant formula powder addition ≤10mg/kg (Chinese standard).
3、Electroplating industry: Acidic plating solution addition 5%-8%, coating uniformity improved by 15%.
4、Wood anti-corrosion: The concentration of the treatment solution is 0.5% -1.5%, and the anti-corrosion period is extended by three times.
