Potassium Zirconium Carbonate

 Potassium Zirconium Carbonate


This Potassium Zirconium Carbonate product is a new type of water-repellent for paper making.
It also can greatly improve the printing properties of coating paper. 

Potassium zirconium salt can cause water-repellent by reaction with synthetic adhesive, modified starch and CMC.
Wide application range of PH value, small use level, nontoxic and etc.


Chemical Engineering 

Environmentally friendly water repellent

Since the materials used in carbonless copy paper CF coatings have hydrophilic hydroxyl groups and other polar groups, the surface of carbonless copy paper has low water resistance. In order to improve the water resistance of paper, a water repellent can be added to the coating. Commonly used water repellents include formaldehyde glyoxal, etc. However, since the hydroxyl groups of starch molecules can cross-link with aldehyde groups to form insoluble complexes, Until the starch loses its swelling ability in water. Moreover, the cross-linking reaction requires a long curing time, and the highest water resistance level can not be reached until two weeks after rewinding. And when the pH of the coating is high, the crosslinking reaction is not easy to proceed. Coupled with environmental protection restrictions on the use of aldehyde mixtures, environmental protection water repellents have attracted more and more attention.

Potassium zirconium carbonate is an environmentally friendly water repellent, it has no chlorine odor and zero formaldehyde release. It can react with the hydroxyl group in starch or the hydroxyl group in synthetic latex. It can make the formulated paint rheological properties better and more stable. The degree of maturation is fast, and the reproduction performance of the dots during printing can be improved, and the printing color is more vivid, which can effectively reduce printing spots and reduce or solve the problem of ink contamination.
