• 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® 375 by allnex is tetramercapto derivative designed as adhesion promotor on metal. It is used in a concentration of 2-10 % in acrylated systems to improve adhesion and flexibility. It may be applied by lithographic, screen, gravure, direct or reverse roll, and curtain coating methods. EBECRYL® 375 is recommended for use in UV/EB cured solder resists and metal- & thick coatings. The shelf life of this product is 2 years.

EBECRYL® 367 by allnex is a low VOC, solvent-free polyester acrylate designed to be used at additive levels in UV/EB inks and coatings to improve adhesion onto plastic substrates.

• It is bisphenol A (BPA)-, tin- free grade and offers low viscosity and low acidity.
• It exhibits low migration, long pot life, low color for clearcoat, faster cycle time, lower energy consumption and low flammability.
• It is suitable for use in radiation curable coating compositions, white flexographic inks, paints and overprint varnishes.
• It may be applied by flexography, inkjet and gravure, direct and reverse roll.
• The typical addition level is 10% by weight or more.
• The shelf life of EBECRYL® 367 is 6 months.

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.
