Coating raw materials will also contain calcium, the experiment proved that raw materials calcium compounds are insoluble in water way, will not increase in the divalent ions in the water.
So the control of production water can greatly improve the water quality and improve the storage stability of the coating and the use of performance.
In fact, the important raw materials of synthetic resin in coatings, it is the application of deionized water production, so in the domestic production of coatings, coatings prepared using deionized water equipment preparation of deionized water is very necessary.
