Defoamers Selection for Industrial Coatings

Review factors that are vital while selecting anti-foaming agents for your industrial coatings formulation. This selection guide will detail you about various classes of defoamers, their functioning and uses in industrial coatings. It would brief you with the risks and benefits linked with each category. This guide would also help you in your defoamer selection according to your substrate, application technology, function of your coating or the film formation chemistry.

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:
