CASE Ingredients Functions
Anti-Foaming AgentDefoamer

PAT-ADD AF 31 is an easily dispersed defoamer for waterborne coatings, aqueous inks and pigment dispersions. PAT-ADD AF 31 is oil-free defoamer based on an organically modified polysiloxane. Although specially developed for lowly pigmented paints and varnishes, PAT-ADD AF 31 is versatile in application. It is a highly efficient defoamer and anti-foaming additive for waterborne during manufacturing and application.

Addition and Dosage

The optimal amount of PAT-ADD AF 31 is system related, generally between 0,1 and 0,4 % on the total weight of formulation. Although the product is easy dispersible in water, effective mixing is still necessary. For use in pigmented systems, we recommended adding half of the required quantity in the pigment dispersion and the remaining half directly to the mill-base or let-down.The optimum concentration used depends on the individual formulation and conditions and is best determined experimentally with a ladder study.
