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® 4513 by allnex is an aliphatic urethane acrylate designed for use in ultraviolet (UV) and electron beam (EB) energy curable coatings. It exhibits elastic properties making it suitable for use with flexible substrates. Coatings formulated with it also demonstrate high chemical- and wear- resistance and are highly resistant to yellowing. It is used to formulate flexible UV/EB energy curable coatings for application by roller-, spraying- & curtain coating and printing on wood, cork, furniture, paper, parquet, plastics, glass & films. EBECRYL® 4513 can also be used to formulate temporary (strippable) coatings.

EBECRYL® 113 by allnex is a low odor, low viscosity, aliphatic monofunctional acrylate with secondary hydroxyl functionality. It exhibits good pigment wetting and allows efficient reduction of oligomer viscosity. It is used as a reactive diluent in ultraviolet light (UV) or electron beam (EB) curing formulations.

• It offers reduced shrinkage & glass transition temperature (Tg), good reactivity, increased flexibility and improved water resistance.
• It is used in screen inks and varnishes, wood sealers & topcoats, coatings for paper and plastic.
• EBECRYL® 113 is suitable for coatings and inks with adhesion to plastics such as polyethylene and plasticized PVC.

EBECRYL® 3608 by allnex is a fatty acid modified epoxy acrylate oligomer diluted with 15% of oligotriacrylate (OTA 480). It is characterized by low odor, light color, low irritancy, excellent pigment wetting properties and good cure response when cured by exposure to ultraviolet light (UV) or electron beam (EB). EBECRYL® 3608 is recommended for lithographic and screen ink and coatings, overprint varnishes, coatings on cardboard, chipboard, paper, rigid plastics and paper upgrading. Cured films exhibit high surface hardness, good solvent resistance and low residual odor. The shelf life of the grade is 2 years.
