Are you using a solid defoamer? Then you have entered a misconception. In the coatings field, we suggest that you no longer choose solid defoamers. The fundamental reasons are as follows:

1. Easy to precipitate

The solid defoamer is generally added in the form of spraying, and the viscosity of the coating is relatively large. In this case, if the solid defoamer particles are relatively fine, it is very likely that the particles cannot be effectively dissolved, which will eventually cause a large amount of The precipitation material.

2. Poor compatibility

Because of the viscosity of the paint, the solid defoamer particles cannot be dissolved, and some of them will precipitate, while the other part is likely to be mixed in the paint and cause the paint to cause impurities. In this way, when the paint is being coated There will be pores, which will affect the overall effect.

3. Increased production costs

Because of the compatibility and precipitation problems of the solid defoamer in the coating, the foam problem of the coating cannot be eliminated in time. In this case, a large amount of defoamer needs to be added, which will increase the overall production cost; Even if the solid defoamer is dissolved in water first and then added later, the function of the solid defoamer will be affected.
