EBECRYL® 820 by allnex is a low viscosity polyester hexaacrylate having exceptional pigment wetting properties. This oligomer is a pigment grinding resin for all process colors and spot colors. It gives a fast cure response when formulated with other oligomers and cured via UV or electron beam (EB). It is developed to formulate UV/EB curable inks for flexography, lithography, gravure or potentially ink-jet and coatings for indirect food packaging. EBECRYL® 820 is ideal for the preparation of high pigment loading pastes using a triple roll mill or bead mill.

EBECRYL® 130 by allnex is a low viscosity, light color cyclic aliphatic diacrylate useful as a reactive diluent in UV (ultra-violet) or EB (electron beam) curable coatings and inks. It imparts a combination of hardness, toughness, and resiliency coupled with improved adhesion properties on various substrates. It also increases the Tg of cured polymers and adhesion. EBECRYL® 130 reduces water permeability and lowers shrinkage. It is applied by lithographic, screen, gravure, inkjet, direct or reverse roll, and curtain coating methods. Recommended for use in scratch-, abrasion- and thermal-resistant coatings. It is suitable for inkjet inks as well as paper- & plastic coatings.

EBECRYL® 152 by allnex is a low-viscosity, clear, solvent free resin for letting down finely dispersed low viscosity pigment pastes. It provides good pigment dispersion stability and improved jetting characteristics in inkjet ink formulations. EBECRYL® 152 offers scratch & solvent resistance, high gloss and no dot gain. It imparts good flow, leveling and adhesion on many types of substrates for UV inkjet ink formulations. The shelf life of the product is 2 years.

Photomer® 4184 distributed by DKSH is a monofunctional urethane acrylate which can be used as a reactive diluent. It is non-yellowing with a low odor and improves flexibility & adhesion.

• It exhibits excellent reactivity, low shrinkage and high elongation and stress at break.
• It is used in plastic, wood, metal coatings and electronics market.
• It is applicable for flexographic, screen-printing inks and inkjet for its good cutting power.
• Photomer® 4184 has a shelf life of 12 months.
• It is available in Japan, Taiwan, South Korea and France.

EBECRYL® 151 by allnex is a low odor, diluting acrylate, grinding vehicle for UV & energy curable inks. It is a low viscosity, clear, solvent-free resin for dispersing all process color inkjet pigments in a bead mill to give a finely dispersed & highly stable pigment paste. This clear free flowing resin is intended for use in the manufacture of inkjet inks. EBECRYL® 151 is recommended for banner and outdoor, POP, labels & packaging, fleet markings, decorative printing and other large format inkjet applications.

Thetawet™ FS-8150 by Innovative Chemical Technologies is a VOC-free, nonionic fluorosurfactant in a low viscosity aqueous solution. It offers excellent wetting benefits which improves wetting of difficult to wet surfaces such as plastics, oily substrates, waxy surfaces and provides excellent surface tension reduction to 18 dynes/cm at low use levels.

• It is 25% active, sparingly water-soluble product which is effective at low end use concentrations.
• This low foam product performs well in severe chemical and thermal environments.
• It is effective in high or low pH, hard or soft water and stable in concentrated acids, bases and oxidyzing solutions.
• It is ideal for use in VOC-sensitive systems.
• Offers narrow-range ethoxylation for high consistency in critical use concentrations such as ink jet medias.
• It is used in paints and industrial coatings.
• It is based on short-chain fluorochemical technology which meets the goal of the US EPA 2010/2015 PFOA Stewardship Program.
• Recommended dosage level is 0.01-0.1%.
• Thetawet™ FS-8150 has a shelf life of 3 years.

Raven 2500 Ultra by Birla Carbon is carbon black for use in industrial and powder coatings, inkjet ink. Suitable for applications where high jetness is required. Raven 2500 Ultra provides greater uniformity, increased compatibility, improved dispersion, better processing, longer screen life, enhanced color development, and reduced scrap.

Raven 2350 Ultra by Birla Carbon is a carbon black. It offers uniformity, increased compatibility, improved dispersion, and better processing. Provides longer screen life, enhanced color development and reduced scrap. Raven 2350 Ultra is suitable for industrial & powder coatings and inkjet ink applications.

UCECOAT® 2804 by allnex is a high performance, UV/EB energy curable polyurethane dispersion for digital printing. It is a low viscosity, low/zero VOC, solvent-, tin-, BPA- and APEO-free grade suitable for indirect food contact applications. Its polymer composition is optimized for high reactivity and low migration potential. It is used as a binder for water-based overprint varnishes, inkjet- and flexographic inks.

• It is tack-free and water re-dispersible after water evaporation but before cure.
• The low grits content allows easy product filterability and good colloidal stability.
• It offers excellent adhesion, faster cycle time, long potlife, low temperature curing and lower energy consumption.
