ZetaSperse Dispersants

Non-Ionic Dispersants & Wetting Agents

ZetaSperse dispersants are a dedicated line of products that address unique challenges of dispersing pigments and other particles efficiently and effectively.

The ZetaSperse range of dispersants for resin-containing systems (ZetaSperse 170, 179, 182, 2500, 3600) 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.

The ZetaSperse range of dispersants for resin-free systems (ZetaSperse 1200, 2300, 2500, 3100, 3400, 3600, 3700, 3800) consists of a variety of polymeric and oligomeric stabilizing chemistries designed to offer performance with a wide range of pigment and particle chemistries and various application demands.

Key Features

ZetaSperse 170:  A nonionic stabilizing surfactant (100% active liquid). ZetaSperse 170 dispersant is a tailored combination of wetting and stabilizing chemistries that provides optimized stabilization of acidic carbon black pigments and polar inorganics like TiO2 in waterborne coatings and inks. ZetaSperse 170 additive is best in conjunction with an anionic dispersant or grind resin.

ZetaSperse 179:  A high HLB nonionic stabilizing surfactant and wetting agent. ZetaSperse 179 dispersant 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 be 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. ZetaSperse 179 dispersant contains no added APEs, offering a good alternative to highly ethoxylated alkyl phenol-based surfactants.

ZetaSperse 182:  A high HLB nonionic stabilizing surfactant and wetting agent.  ZetaSperse 182 dispersant 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 182 dispersant can be 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. ZetaSperse 182 dispersant contains no added APEs, offering a good alternative to highly ethoxylated alkyl phenol-based surfactants.

ZetaSperse 1200:  A high-performance dispersant (45% active solution in water and propylene glycol). ZetaSperse 1200 dispersant is a tailored combination of wetting and stabilizing chemistries. Provides optimized viscosity, gloss, and performance for polar inorganic pigment dispersions, such as titanium dioxide and iron oxides in waterborne coatings and inks.

ZetaSperse 2300:  A high-performance dispersant (95% active liquid with water). ZetaSperse 2300 pigment dispersing additive is a tailored combination of wetting and stabilizing chemistries that provides robust stabilization of most pigment and particle chemistries in waterborne coatings and inks.

ZetaSperse 2500:  A high-performance dispersant (40% active solution in water).  ZetaSperse 2500 pigment dispersing additive is a tailored combination of wetting and stabilizing chemistries that provides excellent viscosity stability and stabilization of demanding organic pigment chemistries in waterborne coating and ink systems.  ZetaSperse 2500 offers exceptional viscosity stability in the dispersion of metal salt pigments and contains no added APEs; as such, it is an alternative to Surfynol CT-171 additive.

ZetaSperse 3100:  A high-performance dispersant (40% active solution in water).  ZetaSperse 3100 dispersant is a tailored combination of stabilizing chemistries that provides outstanding stabilization of carbon black and inorganic pigment dispersions with robust letdown compatibility in waterborne coating and ink systems.

ZetaSperse 3400:  A high-performance dispersant (29% active solution in water).  ZetaSperse 3400 dispersant is a tailored combination of wetting and stabilizing chemistries that provides excellent color and viscosity stability in the dispersion of problematic and high-performance organic pigments such as quinacridone, perylene, azo, and metal complex chemistries in waterborne coating and ink systems.

ZetaSperse 3600:  An anionic/nonionic pigment dispersant and wetting agent (52% active solution in water). It is a proprietary formulation of surface active and polymeric chemistries that provides excellent milling, stabilization, and viscosity benefits in the dispersion of a wide range of organic and carbon black pigment chemistries in aqueous systems. Contains no added solvent or APEs and can be used as an alternative to Surfynol CT-131 and CT-136 additives.

ZetaSperse 3700:  A high-performance dispersant (40% active solution in water).  ZetaSperse 3700 dispersant is a tailored combination of wetting and stabilizing chemistries that provides excellent color and viscosity stability in the dispersion of problematic and high-performance organic pigments such as DPP, phthalocyanine, azo and dioxazine chemistries in waterborne coating and ink systems.

ZetaSperse 3800:  A 40% active solution in water, ZetaSperse 3800 dispersant is based on a nonionic comb polymer designed to offer robust stabilization across all pigment types and chemistries. ZetaSperse 3800 is very forgiving in formulation and a first choice for new formulation development and use across multiple different dispersion formulations.
