WhAT IS FOAM?
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 prevent and destroy the foam bubbles and enable an improved processing, a perfect surface and optimum product properties.
ASTRA offers defoamers which can be used in a variety of different applications. You can divide them into two main groups: silicone defoamers and non-silicone defoamers.
