In the production, filling and application of waterborne coatings, preventing and eliminating foam is an essential process. The absence of foam in the paint film ensures that the coating has good optical appearance and durability. Brands such as TEGO® Foamex, TEGO® Airex, SURFYNOL® and AIRASE®  offer formulators a range of products that are effective in combating foam while maintaining just the right level of compatibility with the coating system. Using different technologies, such as silicon-containing and silicon-free, including the introduction of molecular defoamers, can solve various foam problems including macro- and micro-foam, or achieve rapid foam rupture, etc.
