Conventional waterborne ink formulations are composed of many ingredients including resins, pigments and additives. These additives include waxes, surfactants and defoamers. Surfactants are critical to lowering the surface tension of the ink and to wetting out low energy substrates like films and foils. However, these surfactants can cause foam problems in the formulation during manufacture and application. The defoamers used to remove the foam or to prevent the foam from forming can often caus...
