3. Application
It is widely used in the production of potassium carbonte including KHCO3, Potassium soaps, detergents, fine cosmetic, potassium hydrogen phosphate, potassium permanganate, medical intermediate, liquid fertilizers, synthetic rubber, ABS resin, natural rubber emulsion, paper agent, fermentation, cresol, desulfuration in petroleum refining, Bio-fuel and alkaline battery.
4. Handling and Storage:
Caustic Potash is a highly corrosive substance and requires careful handling.
There should be no contact with bare skin. Caustic Potash flakes should be
Stored under dry conditions away from acids, organic chemicals, metals such as
Aluminum, tin, zinc, lead etc. And their alloys.
