Foam Stabilization Mechanisms

• Foam is naturally unstable

• Bubbles must rise to the surface to break

• Drainage of the liquid surrounding the foam bubbles leads to rupture

• Stability of foam comes from surfactants that hinder drainage

Defoamer Mode of Action

• Defoamers exist as droplets in the liquid and act to destabilize foam by:

• Entering the foam bubble surface

• Spreading along that surface and thinning the liquid layer by forcing drainage

• Bridging the liquid layer to rupture the bubble

• The defoaming process is governed by surface and interfacial tensions

• The surface tension of the defoamer droplets must be lower than that of the liquid

Defoamer Droplet Size

• The defoamer droplets need to be the right size

• If the defoamer droplets are too small, there is an insufficient amount to produce an overall impact

• Defoamer droplets that are too large will result in poor compatibility

• More defoamer droplets of the optimal size will increase the rate of foam breakdown

FOAM BAN® Product Features

• Exceptional initial and long-lasting defoaming

• Excellent compatibility and stability in fluid concentrates

• Superior washability/paintability (i.e., no paint defects)

• Enhanced defoaming persistence during fluid filtration
