Air Products introduces ZetaSperse additives.Air Products has introduced four new ZetaSperse pigment dispersing additives for waterborne coating and ink applications. These new ZetaSperse dispersing additives have been designed to combat viscosity build, color drift, flocculation flocculation /floc·cu·la·tion/ (flok?u-la´shun) a colloid phenomenon in which the disperse phase separates in discrete, usually visible, particles rather than congealing into a continuous mass, as in coagulation. and other challenges faced by dispersion formulators. ZetaSperse 2500 offers robust dispersion viscosity stability, and can be used with problematic pigments, such as metal salt reds and other organic pigment types prone to dispersion rheology challenges. ZetaSperse 3100 is an easy-to-use dispersant dis·per·sant n. Chemistry A liquid or gas added to a mixture to promote dispersion or to maintain dispersed particles in suspension. for carbon black pigments. It offers a unique combination of chemistries that provide broad utility, robust stability, and compatibility across the wide range of carbon black pigment grades. ZetaSperse 3400 is designed for dispersing quinacridone Quinacridone is a red powder. It is an organic compound with the molecular formula C20H12N2O2. It is used as a pigment; analogs bearing this motif are known as quinacridones. , perylene and similar pigment chemistries; this product offers the correct combination of pigment affinity and stabilization to achieve high-quality dispersions with optimal color development, superior color and viscosity stability, and letdown compatibility. ZetaSperse 3700 is designed for the particular challenges of dispersing DPP DPP - Dining Philosophers Problem , azo az·o adj. Containing a nitrogen group, especially N  N.[From azo-. and phthalocyanine phthal·o·cy·a·nine n. Any of several stable, light-fast, blue or green organic pigments used in enamels and plastics. pigment chemistries. It offers the correct combination of pigment affinity and stabilization to achieve high-quality dispersions with optimal color development, superior color and viscosity stability, and letdown compatibility.
