EBECRYL® 812

• Suitable for producing color concentrates via 3-roll mill
• Produces strong, clean, and transparent color when pigmented
• Excellent adhesion to substrates including polystirene (PS), biaxially oriented polypropylene (BOPP), stirene butadiene styrene (SBS) and smooth, high gloss and cast-coated paper stock
• Rapid cure response.
• 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®812 is recommended as a pigment grind vehicle for flexographic inks. Inks based on this oligomer are useful in the narrow web tag and label market as well as the mid web folding carton market.

GRAPH I: EEBECRYL®812 - VISCOSITY REDUCTION WITH REACTIVE DILUENTS

• Graph I shows the viscosity reduction of EBECRYL®812 with dipropylene glycol diacrylate (DPGDA)¹, 1,6-hexanediol diacrylate (HDDA)¹, trimethylolpropane ethoxy triacrylate (TMPEOTA)¹, and tripropylene glycol diacrylate (TPGDA)¹
• 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.
• ¹ Product of allnex

• 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.
