• The shelf life of this grade is 2 years.

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® 3703 by allnex is an amine-modified bisphenol A epoxy acrylate. Suitable for clear coatings for paper & plastics, topcoats for wood, and lithographic- & screen ink vehicles.

• It shows an exceptionally fast cure via exposure to ultraviolet light.
• UV/EB cured products based on EBECRYL® 3703 exhibit good flexibility, high gloss, good abrasion- & chemical resistance, and enhanced adhesion to plastics.
• It may be applied by lithographic, screen, gravure, direct or reverse roll, and curtain coating methods.
• It has a shelf life of 2 years.

EBECRYL® 600 by allnex is a low VOC diacrylate ester of bisphenol A epoxy resin. It provides light color and fast cure response.

• Films cured via exposure to ultraviolet light (UV) or electron beam (EB) possesses high surface hardness and gloss and excellent chemical resistance.
• It reduces energy consumption and exhibits low carbon foot print, good compatibility, low flammability and long potlife.
• It is a radiation curable, solvent- and tin free grade.
• EBECRYL® 600 is recommended for lithographic and screen inks, overprint varnishes and fast cure coatings.
• It is also used in coatings for paper, paperboard, wood, chipboard and rigid plastics.

EBECRYL® 4220 by allnex is an aliphatic urethane acrylate diluted 25% in tripropyleneglycol diacrylate (TPGDA). It produces tough coatings that resist yellowing. EBECRYL® 4220 is designed for use in the formulation of UV/EB energy curable coatings for application by roller coating, spraying and curtain coating on wood, cork, furniture, paper, parquet, plastics and film.

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.

EBECRYL® 11 by allnex is a polyethylene glycol diacrylate derivative. It is 100% water soluble characterized by low viscosity and low color. It offers good flexibility and low water resistance. It is recommended for use in screen inks, wood applications and paper coatings. Formulated UV/EB curable products containing EBECRYL® 11 may be applied by lithographic, screen, gravure, direct or reverse roll, and curtain coating methods. The shelf life of the grade is 2 years.

BLACK PEARLS® 120 distributed by DKSH is a cost-effective, general purpose low color black pigment. It is used as a tinting black in plastics or coatings applications. This economical pigment black can allow higher loadings in most systems and offers very blue undertones. It is also available in an easier to disperse powdered form.

• It offers excellent rub resistance, good viscosity, and flow properties.
• It is recommended for underbody/underhood automotive, general industrial, or architectural trade sales applications where high jetness is not required.
• It can be easily dispersed using a high speed disperser or sandmill for liquid coatings or a single screw extruder for powder coatings.
• It is also used in general dispersions, paper applications, printing inks, concrete, and cement applications.
• BLACK PEARLS® 120 is available in Netherlands, Belgium, Luxembourg, and Myanmar.
