EBECRYL® 8808

EBECRYL® 8808 is characterized by:

• Light color
• No diluting monomers

UV/EB cured products containing EBECRYL® 8808 are characterized by the following performance properties:

• Excellent exterior durability
• Excellent toughness
• Non-yellowing

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

Formulated UV/EB curable products containing EBECRYL® 8808 may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, immersion and spin coating methods, as well as screen printing. EBECRYL® 8808 is recommended for use in:

• Screen inks and coatings on various substrates
• Non-yellowing, exterior durable coatings
• Coatings for wood and plastics

Graph I shows the viscosity reduction of EBECRYL® 8808 with 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA) , tripropylene glycol diacrylate (TPGDA) and 2-phenoxyethyl acrylate (EBECRYL® 114). 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.

EBECRYL® 8808 - Viscosity vs. Temperature

• The recommended storage temperature range for EBECRYL® 8808 is 4°C to 40°C (39°F to 104°F). 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.
