10 Rheological Additives for Solvent, Oil, and UV Inks BENTONE, BENTONE SD,BARAGEL, THIXCIN, THIXATROL, and M-P-A BENTONE, BENTONE SD, and BARAGEL Organoclay Rheological Additives are reaction products of highly purified smectite clay (bentonite or hectorite) and a quaternary ammonium salt. Properly selected and activated, BENTONE organoclays provide the printing ink manufacturer with a reliable means of controlling rheological performance, tack, misting, penetration, and emulsification in paste ink systems while providing excellent anti-settling properties to the liquid ink systems. BENTONE additives effectively impart rheological control in all types of paste inks, including litho news, web offset heatset, and sheet-fed as well as letterpress. They are also useful in metal deco and UV curable inks. Activated organoclay in an ink oil. 10

11 THIXCIN and THIXATROL Organic Rheological Additives are based on castor oil derivatives, modified castor oil derivates, polyamide, or polyester amides. These additives are designed to be used in solvent and UV-based inks and must be subjected to appropriate wetting, deagglomeration, and dispersion forces (at elevated temperature) to reach an activated state.the most appropriate choice of orgaic rheological additive for any given system depends on the required rheology, solvent types, processing temperature, and manufacturing equipment. Organic Rheological Additives are also suitable for solvent-free systems, such as high solids and UV curable inks. Optimum processing temperatures are typically higher than solvent-rich systems. M-P-A Anti-settling Agents are a series of anti-settling additives based on straight-chain ethylene chemistry. These additives are designed to aid in pigment suspension without building viscosity. They perform through chain entanglement and can be used alone or in combination with a thixotrope for added performance. Product selection is typically dependent on the solvent and reactivity of the system to be modified

14 Rheological Additives for Waterborne Inks BENTONE and RHEOLATE BENTONE clay products for waterborne ink systems are based on hectorite, a naturally occurring smectite clay. Hectorite is a hydrophilic-swelling clay composed of silicate sheets that delaminate in water to provide gel structure. Because of this property, hectorite clays have the ability to thicken water and are widely used as rheological additives in waterborne systems. BENTONE clay products are typically used in waterborne flexo and gravure inks to improve the rheological, ink hold-out, and settling properties of the inks.
