As an environmentally friendly coating, water-based industrial paint is widely welcomed because of its low VOC content and good performance. However, during construction, the creation of foam often affects the appearance and quality of the coating. For this reason, we can choose to add an appropriate amount of water-based industrial paint defoamer to solve all kinds of stubborn foam in time. So,Defoamer for water-based industrial paintsWhat are the mechanisms of use and core functions?Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
1. The use mechanism of defoamer for water-based industrial paint
The mechanism of use of defoamers for waterborne industrial paints is mainly based on their excellent surface activity. Water-based industrial paint defoamers can quickly penetrate into the liquid film of the foam, reducing the surface tension and thus destroying the stability of the foam. As the surface tension decreases, the liquid film of the foam becomes thinner and thinner until it breaks and disappears. In addition, some water-based industrial paint defoamers can also form a hydrophobic layer in the system to prevent foam from re-forming.
Second, the core function of water-based industrial paint defoamer
Water-based industrial paint defoamer can quickly eliminate the foam that has been generated, prevent the further expansion of foam, and ensure the smooth progress of the construction processThe water-based industrial paint defoamer also has excellent foam inhibition properties, which can inhibit the regeneration of foam for a long time and provide guarantee for the quality of the coatingBy eliminating air bubbles, water-based industrial paint defoamers help to improve the flatness and smoothness of water-based industrial paint coatings, thereby improving the quality and aesthetics of the coating, making the coating stronger, less likely to fall off, and maintaining stable performance under various environmental conditions.
