Defoamers used in Industrial Coatings
In industrial coatings, waterborne (WB), solventborne (SB) and solventfree (SF) segments are all three largely represented. Defoamers
are needed in waterborne (WB) as well as solventborne (SB) industrial paints. In case of waterborne: during manufacturing as well as application
. For solventborne mainly to avoid foaming during application and avoiding craters and foamy appearance in the dried film.
The table below gives an overview of the different defoamers used in industrial coatings, highlighting their risks and benefits:
