What exactly is a coating defoamer, 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 electrolytes and has high stability. So what are the performance characteristics of defoamer for coating?
1.It can defoam the microfoam produced during the construction or production of building materials, and make the product have good persistence and shear stability while obtaining higher strength and denseness.
2.Can be used in the horizontal or vertical surface systems and all kinds of different carrier systems, especially in the self-leveling system has a very good leveling effect.
3.Make the liquid bubble very little, especially the water-based pulp or mud block which contains almost no air, its defoaming effect is very good. It shows plasticizing effect in some dry powders and improves the coating rate.
4.It has very good operability, mainly in excellent fluidity, no dust, ease of operation, etc.
5.It has good wettability and dispersibility, 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.
