Basic Guidelines

There are several basic guidelines to follow when using silicone antifoams to be the most effective as possible. Silicone antifoams should be prediluted and mixed in with a small amount of the foaming medium prior to introduction into the system. This allows the antifoam to disperse evenly and can prevent shocking of an emulsion, which could cause the emulsion particles to coalesce, or stick together. The antifoam should be dispensed in such a manner as to allow it to disperse evenly and reach the surface of the foaming site. This could involve spraying the antifoam onto the surface, or providing slight agitation when adding the antifoam to allow it to reach the surface. The antifoam should be added prior to the point where foaming occurs. This allows the product to act as it was designed; that is, as an antifoam rather than a defoamer.

When using silicone emulsified antifoams, there are additional precautions that should be taken that involve the amount of shear that the antifoam is subjected to. Because this oil-based antifoam is emulsified using surfactants and thickeners, the product can be destroyed by disturbing the emulsion particles, causing coagulation or separation. High levels of mechanical shear can do this through turbulent agitation, violent shaking, or pumping through gear type, centrifugal pumps. Care should be taken to provide gentle agitation when prediluting, or when adding the antifoam to the foaming process.
