For many industries combating foam is a challenge to overcome.
Pure liquids do not foam or will not form a stable form. However, contaminants such as surfactants, proteins, and small solid particulates will create stable foam in water. Building up foam
would reduce the efficiency of the substance, or entrained air is
undesirable and causes problems with appearance, subsequent dried material, maintenance of proper coating weight, slow
running speed, etc. These foam-related problems are not
immediately seen like defects in the coating, creation of scum, product
separation,
inhibition
of
premature
and
wetting.
Industries use defoamers to diminish the challenges of foams while
sustaining the process runs smoothly throughout. Defoamers is a chemical additive that diminishes the chances of building up foam for the long term.
