Many commodity surfactants used as wetting agents or emulsifiers in water-based emulsion polymerization tend to promote and stabilize excessive foam. Air can also become entrained in a formulation because of applied shear. This entrained air (microfoam) can often impede grinding efficiency, make packing to net weight difficult, cause undesirable surface defects, adversely affect adhesion and water sensitivity, and detract from the aesthetics and/or performance of the finished product. As seen in the figure below, EnviroGem® AD01 surfactant, besides being an excellent wetting agent, also demonstrates outstanding knockdown foam control and antifoaming properties as compared to commodity surfactants. The unique defoaming capabilities of EnviroGem AD01 surfactant can significantly reduce or eliminate the need for additional defoamers in your formulation.
