Cured films of EBECRYL® 436 display good adhesion to metals, plastics and paper. It is recommended for wet lithographic inks for paper, plastics and metals, overprint varnishes and post-formable inks.

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® 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® 811 by allnex is a UV or EB curable polyester acrylate. Inks made using EBECRYL® 811 obtain excellent adhesion to calendered vinyl, polystyrene, polyolefins and PVC. It offers excellent water balance for printing on non-absorbent substrates along with very low misting. It is recommended for offset inks, specifically for printing credit cards and smart cards. It is also used for printing on plastic signage and banners as well as containers.

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.

Photomer® 6621 distributed by DKSH is tin-free, hexafunctional aliphatic urethane acrylate oligomer. It provides very fast cure performance, high hardness, cure speed, scratch-, abrasion-, and solvent resistance.

• It is recommended for use paper, wood and plastic coatings.
• It is suitable for overprint varnishes like offset, flexo, screen and gravure coatings.
• Photomer® 6621 has a shelf life of 6 months.
• It is available in Japan, Taiwan, South Korea and France.

EBECRYL® 230 by allnex is an undiluted high molecular weight aliphatic urethane diacrylate, characterized by its light color and low viscosity. It is most often used as a modifier to improve the flexibility of finished formulations.

• Films of EBECRYL® 230 cured via exposure to ultraviolet light (UV) or electron beam (EB) are soft and resistant to yellowing.
• It is recommended for lithographic- & screen inks as well as coatings for plastics and metals.

EBECRYL® 5848 by allnex is a low-VOC epoxidized soya oil acrylate based in part on renewable resources. It is a BPA (Bisphenol A)- and solvent-free grade. It enhances adhesion and flexibility when used as a modifier in inks and clear or pigmented coatings on paper, wood and metal.

• It exhibits good compatibility, long pot-life, faster cycle time, low-temperature curing, lower energy consumption and low flammability.
• It provides moderate viscosity, improved flow & levelling, good surface appearance and good pigment- & substrate wetting in ultraviolet light (UV) or electron beam (EB) energy curable inks & coatings.
• It offers high gloss potential, improved hardness and good hydrophilic-lipophilic balance for lithography.
• Formulated UV/EB curable products may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, immersion & spin coating methods and flexographic, lithographic and screen printing.
