Architectural coatings play an important role in beautifying the appearance of buildings and protecting building substrates. However, in the process of coating production and construction, the problem of foam often puzzles practitioners. Foam will not only affect the fluidity and coating effect of paint, but also increase the construction difficulty and cost. Therefore, exploring the defoaming technology of architectural coatings is of great significance.

The defoaming technology of architectural coatings mainly relies on the addition of defoamers. Defoamer can quickly dissipate the foam by destroying the stable structure of foam film. At the same time, defoamer can prevent the generation of new foam and ensure the uniformity and stability of the paint. When selecting defoamers for architectural coatings, it is necessary to comprehensively consider factors such as the type of coating, formula, and construction conditions. Different coating systems have different requirements for defoamers, so it is necessary to choose defoamers that match the coating system. With the increasingly strict environmental regulations, environmentally friendly building coating defoamers have become the new favorite of the market. This type of defoamer not only has good defoaming effect, but also reduces the harm to the environment and human body.
