Tallicin® K-9 by Pflaumer Brothers is a polymeric dispersant with multiple anchor groups that can be used to disperse inorganic and organic pigments. It improves pigment wetting, color development and storage stability. It is used in solvent-based coatings, industrial maintenance coatings, offset inks and powder coatings.

• It is effective in reducing viscosity for dispersions of both oxidized and non-oxidized carbon black.
• It allows the formulator to increase the pigment loading in the mill base, thus improving both efficiency and cost of production.
• Recommended dosage level is 2 and 20% based upon pigment weight if the surface area of the pigment is unknown.

EBECRYL® 860 by allnex is an epoxidized soya oil acrylate. Exhibits good hydrophilic-lipophilic balance for lithography and good surface appearance. It improves the flow and leveling of UV or electron beam (EB) curable inks and coatings. It enhances pigment & substrate wetting and adhesion when used as a modifier. Recommended for overprint varnishes for paper, lithographic ink vehicles, metal decorating and protective coatings, screen ink vehicles and pigmented wood coatings. Formulated products containing EBECRYL® 860 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, as well as flexographic, lithographic and screen printing.

Photomer® 6008 distributed by DKSH is a high viscosity, proprietary, aliphatic urethane acrylate oligomer. It is an excellent film former and it contributes towards unique performance properties typical of urethane acrylates in UV/EB curable formulations.

• It exhibits fast cure speed, low odor, skin irritancy and low volatility.
• It is recommended for use in UV/EB curable electronic coatings including solder masks, plate resists, conformal coatings, component coatings and insulating varnishes.
• It is an excellent base resin for screen printing inks where it contributes to consistent application viscosity, better pattern resolution and uniform coating thickness during cure.
• It forms tough, durable films with excellent high temperature stability, superior solvent resistance, high surface hardness and good flexibility when cured.
• It is suitable for lithographic and direct roll methods in addition to screen printing presses.
• It provide high gloss, reactivity, adhesion, yellowing resistance & high build and protection to printed surfaces.
• It is recommended for overprint coatings (varnishes) for paper/paperboard, plastics, metals and wood.
• The shelf life of Photomer® 6008 is 12 months.
• It is available in Japan, Taiwan, South Korea and France.

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.

Luna-nol C-12 distributed by DKSH is a water-based coalescent and retarder solvent. It can enhance the performance properties of the paint and shows good film forming properties.

• It is designed for use in coatings such as architectural, automotive OEM (electrodeposition primers) and can and floor polishes.
