Air Products' specialty additives for dispersion improvement
Dynmic wetting agents, grind aids and co-dispersants
The 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. Our Surfynol®, EnviroGem®, Carbowet®, and ZetaSperse® product lines provide a wide range of surface active additives that can offer superior performance benefits in aqueous dispersions.
Dynamic wetting agents: Surfynol 420, 104, AD01 and Dynol 360 surfactants
These low-foam dynamic wetting agents can rapidly wet the most hydrophobic powders and provide extensive deaeration prior to milling—a critical complement to the first step of the dispersion process. Our Surfynol 420 and 104 surfactants use the acetylenic diol chemistry that has long been recognized as a superior technical solution for wetting and deaeration. Next generation additives, Dynol 360 and Surfynol AD01 lines, can offer even greater performance options.
Grind aids: Carbowet GA-series (GA-100, GA-210, GA-211 and GA-221) surfactants
These surfactants are optimized to provide improved milling efficiency. Functioning through dynamic wetting and a form of dynamic stabilization, these products are used to overcome deficiencies in the dispersant or grind resin. From improved hiding power, higher gloss, greater color or faster color development, the Carbowet GA-series surfactants can provide optimal performance.
Co-dispersants: ZetaSperse 170, 179 and 182 dispersants
Co-dispersants are most effective when used as a secondary dispersant in conjunction with anionic polymeric dispersants and grind resins. These dispersants can provide significant wetting, milling, and steric stabilization benefits, often improving milling efficiency, color development and dispersion stability, and allowing formulators to achieve higher performance. ZetaSperse 170, 179 and 182 dispersants can provide a significant boost to dispersion stability by enhancing steric stabilization mechanisms and are typically used to control dispersion viscosity, improve resistance to flocculation in letdown, and provide general stability benefits.
