Foam is a dispersion of gas bubbles in a liquid, which is formed by the presence of surfactants in the medium. In our everyday life we are accustomed to using products that foam up, such as shampoos or detergents, among others. Industrially, however, foaming is not always desirable, as it can cause a decrease in production yield and results in poor-quality finished products.

In the decorative paint industry, excess foam may cause an increase in production time, cause problems during packing and cause deficiencies in the final appearance of the coating. Thus, it is essential to use an anti-foaming agent that allows optimal control of foam formation during production stages and keeps its properties during storage. Thus, paint with a smooth finish that is free of craters and fisheyes can be obtained.
