DOSAGE

Typical addition level of Potassium Zirconium Carbonate is recommended as under:

Paper Coating6-8 % wet basis on binder solids
Aqueous Paints6-8 % wet basis on binder solids
Aqueous Inks and Coating5-10 % wet basis on the total dry binder solids.

Dosage can vary depending upon the degree of cross-linking property enhancement required. The pH of the coating before the addition of Potassium Zirconium Carbonate should be higher than 7. It should be always added as the last component in the formulation, after adjusting the pH at 8-9.

 

STORAGE

For storage stainless steel, Polyethylene or polypropylene are suitable. Mild steel is not recommended. Potassium Zirconium Carbonate should be stored in tightly sealed drums It is not advisable to leave open the used drums of Potassium Zirconium Carbonate. The air within the containers can slowly react with the product leaving solid sediments at the bottom.

 

Shelf Life of 6 months from the date of manufacturing stored in air tight sealed containers away from direct heat and sunlight.
