Resolving Foaming Issues in Paints, Coatings and Inks

Foam is an undesirable object formed during the production of paints, coatings and inks. This anomaly can cause major surface defects during application. Foaming can occur during the production process, where it leads to the wastage of space in the production vessels. Foaming not only effects efficiency, but also effects the quality and protection functionality of paints and coatings.

Almost all elements present in paints, coatings and inks can influence the behavior of foam, either positively or negatively. Apart from this, the type of substrate and the method of application can have an impact as well. The situation governs the removal of foam and usually coatings cannot be defoamed. For example, a specific spray application could result in exceptional film properties, however, the use of the same paint in a curtain coater operation could lead to foaming issues.
