In the production and application process of architectural paint, foam problems often trouble manufacturers and users. Foam not only affects the appearance and quality of the paint, but may also reduce the performance and use effect of the paint. In order to solve this problem, architectural paint defoamers came into being. This article will introduce the relevant knowledge of architectural paint defoamers in detail, including its role, characteristics, types and applications.

In the production process of architectural paint, due to process operations such as stirring and emulsification, as well as the composition characteristics of the paint itself, a large amount of foam is easily generated. These foams will cause the volume of the paint to expand, affect the utilization rate of production equipment, and increase production costs. At the same time, the foam will also change the surface tension of the paint, affecting the coating performance and drying speed of the paint.

Architectural paint defoamers should be able to quickly reduce the surface tension of the foam, make the foam break quickly, and be able to control the re-generation of foam for a long time. It should have a good defoaming effect on different types of foam, including large bubbles and micro bubbles.

There are generally two ways to apply architectural paint defoamers: one is to add it during the paint production process, and the other is to add it at the paint use site. Adding defoamer during the paint production process can make the defoamer fully dispersed in the paint and better play its defoaming role. Adding defoamer at the paint application site can flexibly adjust the amount of defoamer according to actual conditions.

In summary, architectural paint defoamer plays a vital role in the production and application of architectural paint. It can effectively eliminate foam, improve the production efficiency and performance of paint, and also has a variety of excellent characteristics and different types to choose from.
