What are Defoamers?

Defoamers are chemical additives that reduce and/or prevent the formation of foam in industrial

process liquids such as paints, inks, adhesives and even construction products. The terms antifoam agent and defoamer are often used interchangeably,

however, antifoam agents more accurately refer to materials that inhibit the generation and formation of bubbles. Dependent upon the application and

performance requirements, they consist of polydimethylsiloxanes and other silicones, insoluble oils, stearates and glycols, as well as inorganics, such as

silicates and talc.

What is Foam?

Foam is a coarse dispersion of a gas in a liquid, where the volume fraction of gas is greater than that of the liquid. The bubbles will migrate to the

surface, as their density is less than that of the liquid. As the bubbles coalesce and collect at the air/surface interface, the bubble walls thin and break.
