EBECRYL® 3605 by allnex is a light color, partially acrylated ester of a bisphenol A type epoxy resin. It contains both acrylate and epoxy functionality. It may be cured by exposure to either ultraviolet light (UV) or electron beam (EB) in conjunction with conventional epoxy curing. It may also be cured with UV radiation using a mixed photoinitiator system consisting of free radical and cationic photoinitiators. It is developed for applications requiring improved coating performance properties over those obtainable with conventional UV/EB curing alone. It is recommended for coatings and inks for metal substrates including aluminum. It is designed for applications requiring fast cure speed of an epoxy acrylate with improved flexibility and superior adhesion to rigid, non-porous substrates. EBECRYL® 3605 offers high gloss finish, surface hardness and good solvent resistance. Formulated products 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 offset and screen printing. It is suitable for dual (UV/thermal)- and two component- curing systems.

SYNA S-21 distributed by DKSH is a distilled base epoxy resin. It is a low VOC grade and provides low odor and primary film properties. It has both carboxylate and epoxy groups, with the potential for fast cure. It is used in formulating UV-curable cycloaliphatic epoxide coatings systems.

• It is widely used in industry for the preparation of inks and coatings.
• It offers excellent adhesion to a wide variety of substrates.
• Possesses low viscosity and rapid polymerization in the presence of strong cationic initiators.
• The shelf life of SYNA S-21 is 2 years.
• It is available in Asia, Europe and North America.

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.

Epotec® YDH 184 distributed by DKSH is an epoxy resin based on diglycidyl ester of hexahydrophthalic anhydride. It gives better non-yellowing characteristics and chalking resistance. It offers good UV light and weather resistance. It can also be cured with anhydride curing agents at high temperatures.

• It has low VOC and solvent-free formulations.
• The applications include coatings for outdoor application on metal, wood and concrete surface, high solids coatings including baking finishes and for potting and insulating compound coatings.
• It has a shelf life of 2 years.
• Epotec® YDH 184 is available in Canada.

YN-1828 distributed by DKSH is a medium viscosity liquid epoxy resin produced from bisphenol A and epichlorohydrin. It contains no diluents.

• It provides good pigment wetting and good resistance to filler settling and high level of mechanical and chemical resistance properties in the cured state.
• It is recommended for solvent-free and high-solid coatings.
• The shelf life of YN-1828 is 1 year.
• It is available in Australia, Indonesia, Italy, Malaysia and Thailand.

Epotec® YDH 3000 distributed by DKSH is a diglycidyl ether of hydrogenated bisphenol-A epoxy resin with cyclic rings of saturated bisphenol-A. This resin is expected to give good resistance to ultraviolet light and weathering which is a limitation when it comes to standard bisphenol-A based epoxy resins.

• It gives better non-yellowing characteristics and chalking resistance.
• The choice of curing agent also plays an important role in getting better performing formulations.
• Applications of Epotec® YDH 3000 include coatings for outdoor application on metal, wood and concrete surface, high solid coatings including baking finishes and modifier for industrial acrylic finishes.
• It has a shelf life of 2 years.
• It is available in Canada.

Epotec® YDFM 253 distributed by DKSH is a blend of diglycidyl ether of bisphenol-A liquid epoxy resin, diglycidyl ether of bisphenol-F liquid epoxy resin and mono-functional reactive diluent. It improves the crystallization resistance. The reactive diluent in the blend helps in reducing the viscosity of the product so that it can be suitably formulated into high solids or even solvent free coatings and floor toppings.

• The reactive diluent in the blend also lowers surface tension of the product and increases pot life as well as flexibility of the system.
• This translates into better surface wetting, longer working time and improved toughness.
• Epotec® YDFM 253 is compatible with all common epoxy resins in all ratios.
• It is used in marine and industrial protective coatings.
• It has a shelf life of 2 years.
• It is available in Canada.

Epotec® YD 126 distributed by DKSH is an unmodified liquid epoxy resin produced from bisphenol-A and epichlorohydrin processed to produce lower viscosity than standard liquid epoxy resin without any modification by diluent. It possesses good strength, adhesion & very low shrinkage.

• It is suitable for use in varied applications including protective coating, automotive coatings, can & coil coatings, marine and industrial protective coatings.
• It is also used in solvent-based, high solids and solvent-free coatings.
• It has a shelf life of 2 years.
