EBECRYL® 5850

EBECRYL® 5850 is characterized by

• Medium viscosity
• High reactivity
• Excellent balance of hardness and flexibility
• High Tg
• High renewable content (56%)
• Especially effective in UV LED formulations

The actual properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives and photoinitiators.

EBECRYL® 5850 is recommended for use in:

• BPA-free overprint varnishes and coatings
• Wood coatings
• Ink binders

Formulated UV/EB energy curable products containing EBECRYL® 5850 may be applied by flexography, screen, gravure, and direct or reverse roll coating.

• Viscosity reduction of EBECRYL® 5850 is possible with common reactive diluents such as 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA).
• Although viscosity reduction can be achieved with non-reactive solvents, reactive diluents are preferred because they are essentially 100 percent converted during UV/EB exposure to form a part of the coating or ink, thus reducing solvent emissions.
• The specific reactive diluents used will influence performance properties such as hardness and flexibility.

• Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids. This might cause uncontrollable polymerization of the product with the generation of heat.
• Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers. Procedures that remove or displace oxygen from the material should be avoided. Do not store this material under an oxygen free atmosphere.
• Dry air is recommended to displace material removed from the container. Wash thoroughly after handling. Keep container tightly closed. Use with adequate ventilation.
