Abstract

In this paper, it was attempted to study the foam formation phenomena in the surface coating systems. Firstly, the terminology and some fundamental definitions in the foaming and its importance in surface coating are presented. Since the elimination of foam requires a profound knowledge about how foam is stabilized, the foam stabilizing mechanisms are given. Finally, various mechanisms and materials that are capable to destabilize the foams in the coating formulations are introduced.
