How to make coating defoamer fully play its role
In our daily work, how to make the paint defoamer fully play its role and its correct use method are very important. Let’s learn more about the paint defoamer from the aspects of the selection and performance of the defoamer.
1. Paint defoamers are not universal, so in different emulsions or water dispersion systems, the types of paint defoamers used are also different. You can choose a variety of defoamers for trial, and select a paint defoamer product with high performance and cost performance after test comparison.
2. High-quality paint defoamers not only have good defoaming effects, but also have lasting anti-foaming effects.
3. Any defoamer will gradually fail during storage with changes in the environment and the extension of time, so it is very important to stabilize the performance of the paint defoamer so that it will not fail quickly.
4. On the basis of maintaining good defoaming properties, high-quality paint defoamers will not produce shrinkage holes when used in a slightly larger amount. Because only in this way can we avoid the phenomenon of the defoamer gradually failing over time after adding a large amount of defoamer in the initial stage.
5. For general coatings, it is sufficient to choose a low-cost mineral oil defoamer, which can reduce the cost of the defoamer; for high-performance coatings, it is necessary to consider whether the use of the defoamer will affect the performance of the coating. In addition, this type of coating emulsion is used in large quantities and is prone to foaming, so a high-performance coating defoamer should be selected.
Only by choosing the right method to use the coating defoamer can it fully play its role and achieve the best effect.
