Usage

Silway 140 silicone antifoam emulsion is an excellent candidate for commercial used in both water-based systems and surfactant concentrates. It can therefore be added directly to these systems without pre-dilution and mixed with slow to moderate agitation to ensure a complete and homogenous dispersion. 

The addition levels of Silway 140 silicone antifoam emulsion, when used in the final foaming system, will be dependent upon the nature of the foaming system and the type of agitation generating the foam. A recommended starting point is addition of sufficient Silway 140 silicone antifoam emulsion that would give between 1 ppm and 50 ppm of antifoam (based on solid content) into the final foaming formulation. 

As with any water-based formulation, it is recommended to confirm that the foam control agent remains dispersed once added to the formulation.
