Defoamers & deaerators for waterborne coatings | Evonik

When dealing with coatings we know there might be no moment without the risk to create foam. All this foam lead in a lot of problems like the loss of weather resistance or corrosion protection. To get rid of that macro and micro foam we need defoamers and dearators.

See a theoretical and practical approach on how to combat foam in waterborne systems.

No doubt the prevention and elimination of foam is essential during production, filling and application of waterborne coatings. Foam free films guarantee an excellent optical appearance and durability of the coating. The product group TEGO® Foamex, TEGO® Airex, SURFYNOL® and AIRASE® offer a variety of products to the formulator finding the right balance of effectiveness against foam and compatibility with the coating system.
The full spectrum of foam issues such as macrofoam, microfoam or fast foam breakdown can be solved by selecting the best suitable chemical nature from the vast array of options such as silicone-based or silicone-free or utilizing the concept of molecular defoamers.
