Sodium carboxymethyl cellulose (CMC) is widely used in the field of coatings. The addition of CMC improves the water retention of the paint and helps to coat in wet environments. And CMC, as a defoamer, can reduce the foaming, pinhole and cracking of the coating film, thereby improving the appearance and impact resistance of the coating. In addition, CMC can also improve the construction performance of the coating, improve the wetting ability of the coating on the construction substrate, reduce the coating mixing time, make the coating easier to coat, and thus improve the production efficiency.
