What is defoamer for paint?

What exactly is a defoamer for paint,let's find out together. It is a non-ionic surfactant suitable for cement dry mortar. Its hydrophilic group is a non-ionic group-hydroxyl and ether group, so it is not affected by the pH value of the medium and the electrolyte, and has high stability. So what are its performance characteristics?
1. It can defoam the microbubbles generated in the construction or production process of building materials, and make the product have good durability and shear stability, while obtaining higher strength and compactness.

2. It can be used in horizontal or vertical systems and various carrier systems, especially in self-leveling systems with good leveling effect.

3. Make the liquid have few air bubbles, especially the water-based slurry or mud that hardly contains air, and its defoaming effect is very good. In some dry powders, it shows a plasticizing effect and improves the spreading rate.

4. Good operability, mainly manifested in excellent fluidity, no dust, easy operation, etc.

5. It has good wetting and dispersing properties, especially in the self-leveling system, it can be well wetted by water and evenly dispersed in the system, without causing surface defects such as oil spots and color difference.

Defoamer for paint is suitable for self-leveling system, thin-layer system, tile adhesive (cement-based), caulking agent (cement-based), mortar system, gypsum system, dry powder coating, etc.
