Tallicin® K-8 by Pflaumer Brothers acts as a dispersing agent. It helps produce a high gloss effect as it eliminates bubbles and craters seen in dip tank applications. it is used to disperse inorganic and organic pigments in a variety of systems such as solvent-based coatings, inks, powder coatings.

• it improves pigment wetting, color development, and storage stability.
• Tallicin® K-8 allows the formulator to reduce the viscosity or increase the pigment loading in the mill base thus improving both efficiency and cost of production.
• it is used in industrial maintenance coatings, offset inks, and product finishes.
• Recommended dosage level is 2 and 20% based upon pigment weight if the surface area of the pigment is unknown.

EBECRYL® 3701 by allnex is a VOC-, solvent- and tin-free, modified bisphenol A epoxy diacrylate. It imparts flexibility and toughness to ultraviolet light (UV) or electron beam (EB) cured coatings and inks, while maintaining fast cure response and superior chemical resistance that are typical of standard epoxy acrylates.

• It provides high gloss, and good abrasion and impact resistance.
• Formulated UV/EB curable products containing EBECRYL® 3701 may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife-over-roll, air knife, curtain, immersion and spin coating methods.
• It is recommended for clear coatings for paper, wood and rigid plastic, as well as lithographic, screen and flexographic ink vehicles.

EBECRYL® 578 by allnex is an inert resin diluted in trimethylolpropane ethoxylate triacrylate (TMPEOTA). It possesses medium viscosity, and is VOC-, chloride- and solvent-free. It is developed for ultraviolet light (UV) or electron beam (EB) cured offset lithographic inks and coating.

• It provides good adhesion to various substrate such as metallic and plastic materials.
• It exhibits good pigment wetting and high reactivity and cure speed, and low color for clearcoat.
• EBECRYL® 578 is used in other applications such as screen, gravure, flexo and overprint varnish.
