During the production and application of water-base systems, foam is an undesired side-effect that increases production time, makes it more difficult to fill vessels with the correct amount of paint, and contributes to surface defects such as craters and weak points in the dried film.
Foam control agents are paint additives that are capable to reduce or suppress the stabilization of air bubbles and further formation of foam. They prevent mottled surface appearance and pinholes and give smooth and beautiful films. They also enhance paint film durability and gloss value. At the paint production stage, they help to get pigment dispersions of better yields and lower viscosity.
