EBECRYL® 444

EBECRYL® 444 is characterized by

• Good wet lithographic behavior
• Fast curing
• Low odor

UV/EB cured formulations based on EBECRYL® 444 are characterized by the following performance properties

• Good adhesion to metals, and paper

The actual properties of UV/EB cured formulations also depend on the selection of the other formulation components, such as reactive diluent(s), additives and photoinitiators.

UV/EB curable formulations containing EBECRYL® 444 may be applied by lithographic, screen, gravure, direct or reverse roll, and curtain coating methods. EBECRYL® 444 is recommended for use in:

• Wet lithographic inks and coatings for paper, and metals
• Adhesion promoter for inks and coatings on metals, and paper

• EBECRYL® 444 can be further diluted with OTA-480 or other reactive monomers such as, 1,6-hexanediol diacrylate (HDDA), tripropylene glycol diacrylate (TPGDA) or trimethylolpropane triacrylate (TMPTA).
• 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.
