EBECRYL® 8800-20R

EBECRYL® 8800-20R is characterized by:

• Light color
• Crystalline semi-solid
• Low odor

UV/EB cured products containing EBECRYL® 8800-20R are characterized by the following performance properties:

• Excellent abrasion resistance
• Toughness
• Exterior durability
• Flexibility
• Chemical resistance
• 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® 8800-20R 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. EBECRYL® 8800-20R is recommended for use in:

• Wood and vinyl floor coatings
• Coatings requiring exterior durability
• Coatings for wood and plastic

Graph I - EBECRYL® 8800-20R - Viscosity reduction with reactive diluents

Graph I shows the viscosity reduction of EBECRYL® 8800-20R with 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA). 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.

Graph II - EBECRYL® 8800-20R - Viscosity vs. Temperature

Graph II illustrates the change in viscosity of EBECRYL® 8800-20R with increasing temperature.

• 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.
• Upon storage, EBECRYL® 8800-20R may show signs of crystallization. This crystallization can be removed by heating containers of EBECRYL® 8800-20R to a uniform temperature of 60°C.
• Ovens or hotboxes are recommended methods of heating. Heating tapes should not be used. In typical formulations, EBECRYL® 8800-20R does not exhibit signs of crystallization.
