Foam is a dispersion of a gas in a liquid. The occurrence of foam when producing and processing coatings, printing inks, plastic materials, but also in many other industrial processes, is usually not desired. Defoamers or air release agents prevent and destroy the foam bubbles and enable an improved processing, a perfect surface and optimum product properties.
BYK offers defoamers which can be used in a variety of different applications. You can divide them into three main groups: silicone defoamers, mineral oil defoamers and polymer defoamers.
