Defoaming

Defoamers prevent and destroy foam (air bubble formation) during manufacture and application of water-based coatings and printing inks. They are available in emulsion, solution or concentrate form. Emulsions have the advantage of optimized particle size for maximum efficacy and compatibility even at the let-down stage. Concentrates are ideal for the use at the grinding stage.
