Defoamers & Deaerators
Among the names Surfynol® and Airase® EVONIK carries a wide range of defoamers and deaerators for aqueous systems. Depending on the demands on the additive in the final formulation (shear stability, long term stability, compatibility, surface quality) the right additives can be found to address micro and macrofoam.
The products range from defoamers based on organic oil and silicone, via siloxane based deaerators, right down to the unique molecular defoamers.
One highlight is a range of products called Airase® SSDL (Structured Siloxanes Defoamer Line). These are seven well-matched siloxane defoamers - a kit that makes it easy for users to find the right defoamer for their demand.
Fields of application are for example automotive coatings, wood coatings, emulsion paints, printing inks, adhesives and cleaners.
