Additives for dispersions: wetting agents, grind aids and dispersants

Formulation of an optimal dispersion can be a daunting task, but the addition of an Air Products additive can quickly improve your formulation’s performance to enable you to achieve your targets. While dispersants provide the primary stabilization in a dispersion, additional surface-active additives are often used in a formulation to enhance performance. Our Surfynol®, Carbowet®, ZetaSperse®, and Airase® product lines provide a wide range of surface-active additives that can offer superior performance benefits in aqueous dispersions—these can be grouped into four basic categories: low-foam dynamic wetting agents, grind aids, stabilizing surfactant dispersants, and defoamers. The characteristics of the first three categories are illustrated in the table below.
