I’m working on some new formulations, and the defoamers I usually work with aren’t working. Why is this, and how can I quickly find a suitable defoamer for my new formulation?

Jim Reader
Lead Research Chemist

The performance of a defoamer is affected by the nature of the formulation it is being used in; familiar products that have worked well in the past may not work as expected when used in different formulation types. Changes in the binder chemistry, the amount of both binder and solid materials such as pigments and fillers, can affect the defoamer performance, as well as viscosity and the presence of strong surfactants.

The AiraseTM Structured Siloxane Defoamer Line (SSDLTM defoamers) is a range of defoamers that have been developed with predictable performance relative to each other so as to allow a systematic approach to defoamer selection. The performance of one defoamer in a given formulation can be used to forecast how the other defoamers will behave in the same formulation; if the first attempt isn’t successful, you can choose your next defoamer to test more logically and find an answer quicker than with the traditional “next bottle on the shelf” approach.
