EBECRYL® 8809

EBECRYL® 8809 is characterized by:

• No intentionally added tin, heavy metals*, or quinones
• Light color
• No diluting monomers

UV/EB cured products containing EBECRYL® 8809 are characterized by the following performance properties

• Regulation friendly for tin, heavy metals*, and quinones
• 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 8809 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 8809 is recommended for use in:

• Applications that must meet regulations for tin, heavy metal*, and quinone content Screen inks and coatings on various substrates
• Non-yellowing, exterior durable coatings
• Coatings for wood and plastics

• Regulation friendly for tin, heavy metals*, and quinones
• Excellent exterior durability
• Excellent toughness
• Non-yellowing

EBECRYL® 8809 - Viscosity Reduction With Reactive Diluent

Graph I shows the viscosity reduction of EBECRYL 8809 with 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), tripropylene glycol diacrylate (TPGDA) and 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.

EBECRYL® 8809 - Viscosity vs. Temperature/p>

• 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.
