EBECRYL® 571

EBECRYL® 571 is characterized by:

• Moderate viscosity
• High reactivity

UV cured products containing EBECRYL® 571 are characterized by the following performance properties:

• Excellent adhesion to shrink PVC, PET-G, SBS and PLA
• Excellent shrink properties
• Shrink and contour without diskoloration
• Excellent wrinkle resistance

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

UV/EB curable products containing EBECRYL® 571 may be applied by flexographic, screen, gravure, direct or reverse roll, and curtain coating methods. EBECRYL® 571 is recommended for:

• Flexographic inks and coatings for shrink sleeve applications

• EBECRYL® 571 can be further diluted with DPGDA or other reactive monomers such as, 1,6-hexanediol diacrylate (HDDA), tripropyleneglycol diacrylate (TPGDA), trimethylolpropane ethoxy triacrylate (TMPEOTA), trimethylolpropane triacrylate (TMPTA), or EBECRYL® 40.
• 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.
