EBECRYL® 811

• Primary component for wet or dry offset inks to be printed on plastics
• Excellent water balance for printing on non- absorbent substrates
• Excellent adhesion to a variety of plastic substrates including calendered vinyl, polystirene, polyolefins, polycarbonate and PVC
• Neither chlorinated nor acidic in nature
•  Very low misting
   

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® 811 is recommended for wet or dry offset inks, specifically for printing credit cards and smart cards. It may also be used for printing on plastic signage and banners as well as containers.

At 400 RPM, 90°F, 3 minutes; Thwing-Albert Electronic Inkometer.

Graph I show the viscosity reduction of EBECRYL® 811 with the reactive diluents EBECRYL® 140 (ditrimethylolpropane tetraacrylate), OTA-480 (propoxylated glycerol triacrylate), TMPTA (trimethylolpropane triacrylate) and TPGD (tripropylene glycol diacrylate). 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 avoiding 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.
