Silicone anti-foam / de-foamer products are used as process aids in the manufacturing process where foaming is prevalent. Foam is generated by agitation of liquids through, stirring, shaking, boiling, mixing, evacuation and filling under high speed conditions. The presence of foam can result in: loss of capacity, as foam displaces product; inefficient mixing and pumping; separation; excessive wastage of product and increased processing time.

​

Antifoam and de-foamer products are often inter-changeable but generally there is a functional difference:
1. A product acts as an antifoam when it is added to a system prior to foam formation and serves to prevent the generation of foam, i.e. application by pre-dosing.
2. A product acts as a de-foamer when it is added to a system after foam has been generated.
