Dispersants for Resin-Containing Systems

The ZetaSperse® range of dispersants for resin-containing systems consists primarily of nonionic dispersants designed to provide steric stabilization benefits to systems based on anionic grind resins or polymeric dispersants. These products offer a range of performance advantages, including improved dispersion stability, reduced dispersion viscosity or higher pigment loadings, improved color stability as well as increased letdown compatibility and resistance to shock and flocculation. Additional ZetaSperse dispersants are also listed that have shown benefits when combined with grind resins or other dispersants.

ZetaSperse 170

Lower in molecular weight, ZetaSperse 170 dispersant was designed for optimal performance with acidic surface groups such as carbon black. It is a tertiary amine and provides strong affinity for acidic substrates and its nonionic character adds strong steric stabilization. ZetaSperse 170 dispersant is most effective when used as a secondary dispersant with anionic polymeric dispersants for organic and inorganic pigments. It provides a boost in stabilization and can typically lower dispersion viscosities, allowing for higher solids loadings and improved overall dispersion stability.

ZetaSperse 179

ZetaSperse 179 dispersant is a high HLB nonionic stabilizing surfactant and wetting agent. It offers excellent nonionic stabilization properties for dispersion, emulsification and surfactancy benefits in a variety of waterborne applications including coatings, inks and adhesives. In pigment dispersions specifically, ZetaSperse 179 dispersant can used in the milling phase as a co-dispersant to improve the dispersion characteristics of an anionic polymeric dispersant as well as added during letdown to improve compatibility and color acceptance. With no added APEs, ZetaSperse 179 offers an alternative to highly ethoxylated alkyl phenol-based surfactants.

ZetaSperse 2500

Lower in molecular weight, ZetaSperse 2500 dispersant provides electrosteric stabilization based on a special anchoring group particularly suited for aromatic solids. It provides strong affinity for organic and carbon black pigments. ZetaSperse 2500 dispersant is optimized for performance in resin-free and resin-minimal formulations, but, due to its specially designed structure, it offers some favorable interactions with typical polymeric dispersants and can also be effective at low use levels to improve dispersions. ZetaSperse 2500 dispersant is a 40% active aqueous solution.

ZetaSperse 3600

A 52% active solution in water, ZetaSperse 3600 dispersant is based on a synergistic combination of surface active agents and is designed to provide robust and easy-to-use performance across most pigment and particle chemistries. It is also a very effective solution for overcoming variation in pigment supply and quality. Although designed as a primary dispersant for use in resin-free and resin-minimal systems, due to its properties, ZetaSperse 3600 dispersant offers favorable stabilization benefits when used as a secondary dispersant in conjunction with other dispersants.
