Chemical processing additives such as Defoamer Chemical, antifoaming agents, and air release agents are used to reduce or remove foam in industrial operations. While the phrases are frequently used interchangeably, they involve distinct methods, so it is important to know the difference. Defoamers are foam management chemicals that are introduced to a system after it has developed to decrease or remove foam. Antifoaming agents are foam-control chemicals that are applied to a system or formulation to prevent foam from forming. Air release agents aid in the removal of entrained gases from a solution and their subsequent elevation to the surface.
