Be careful when using defoaming agents
The amount of defoaming agent must be strictly controlled when used, and it is not allowed to be added without permission. Select the appropriate amount according to actual needs. The specific application method is as follows:
1. Application in coatings. Improper use of defoaming agents in coatings can cause side effects, causing the gloss of the paint film to decrease, seriously affecting product quality, and reducing adhesion and water resistance. Therefore, we must pay attention to the assessment of comprehensive performance, pay attention to the selection of defoaming agent types and strictly control the amount of addition.
2. Stir evenly before use. When adding, add it slowly with stirring. If necessary, add it step by step to get satisfactory results. The shear force during stirring is used to ensure a good distribution of the particle size of the defoaming agent. However, excessive shear force makes the defoaming agent particles too small and weakens the defoaming effect. Therefore, it is very important to master the mixing method.
In short, mastering the use of defoaming agents can not only ensure the normal operation of production, but also ensure that there is no foaming during construction, maintain its stability, and strive to create a good surface environment!
