High-build paint

High-build paint is a high-solid paint that is usually composed of polymer materials, solvents and fillers. Its viscosity is relatively high, forming a thick coating. The generation of bubbles is often a headache. In order to solve this problem, high-build paint defoamer came into being. This article will delve into the characteristics and functions of thick-build paint defoaming agents.

1. Features:

1. Efficient defoaming: It has excellent defoaming performance and can quickly destroy foam in the liquid and prevent the formation of new foam.

2. Temperature resistance: Since high temperature conditions may exist during the coating production process, high-quality thick-build paint defoaming agents have good temperature resistance and can effectively eliminate foam in high-temperature environments.

3. Good compatibility: It should have good compatibility and be compatible with other components in the paint without adversely affecting the performance and quality of the paint.

4. Stability: It has good stability, can maintain its defoaming effect during the storage and use of paint, and is not easy to decompose or fail.

2. Function:

1. Eliminate foam on the paint surface: It can quickly penetrate into the foam in the paint, reduce its surface tension, and quickly collapse and eliminate the foam, thus improving the surface quality and appearance of the paint.

2. Improve the wettability of paint: It can improve the wetting performance of paint, so that it can better cover the surface of the coated object and reduce defects and unevenness on the paint surface.
