The role and advantages of defoamers in water-based paint
Function
Eliminate foam:
Defoamers can quickly destroy the foam structure in water-based paint, making the foam disappear quickly, thereby ensuring the smoothness and glossiness of the paint.
During the production and construction of water-based paint, a large amount of foam is easily generated due to stirring, pumping or mixing of air impurities. If these foams are not controlled in time, they will cause defects on the surface of the paint, such as dents, fish eyes, etc. The use of defoamers can effectively solve this problem.
Prevent foam regeneration:
Defoamers not only have the ability to quickly defoam, but also effectively prevent the re-generation of foam, ensuring the stability and continuity of the paint process.
Improve production efficiency:
By eliminating foam, defoamers can reduce the generation of surface defects in the paint, thereby improving the qualified rate of the product.
At the same time, the use of defoamers can also reduce the waste of paint during the coating process and reduce production costs.
Advantages
High efficiency:
Defoamers can quickly and effectively eliminate foam in water-based paint and improve production efficiency.
Stability:
Defoamers have good stability and can maintain good defoaming performance under harsh conditions such as high temperature and high shear.
This means that during the paint baking process, defoamers can continue to play a defoaming role and prevent the re-generation of foam.
Compatibility:
Defoamers have good compatibility with water-based paint systems and will not have adverse effects on other properties of the paint.
This allows defoamers to be widely used in various water-based paint systems to meet the needs of different customers.
Environmental protection:
Defoamers are made of environmentally friendly materials, do not contain harmful substances, and are harmless to the environment and human health.
This meets the requirements of modern green production and helps promote the sustainable development of the water-based paint industry.
Easy operation:
Defoamers are easy to mix with paint and are easy to use.
When adding, just add the defoamer to the paint in a certain proportion and stir it thoroughly.
In summary
defoamers have multiple functions in water-based paint, such as eliminating foam, preventing foam regeneration, and improving production efficiency. They also have significant advantages such as high efficiency, stability, compatibility, environmental protection, and easy operation. These advantages and functions make defoamers an indispensable and important auxiliary agent in water-based paint.
