EBECRYL® 294/25

EBECRYL® 294/25 is characterized by:

• Light color

UV/EB cured products based on EBECRYL® 294/25 are characterized by the following performance properties:

• Excellent abrasion resistance and stain resistance
• Good exterior durability
• Toughness
• Non-yellowing

Formulated UV/EB curable products containing EBECRYL®® 294/25 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®® 294/25 is recommended for use in:

• Clear coatings for wood and vinyl flooring
• Exterior durable coatings
• Coatings requiring high abrasion resistance, stain resistance and toughness

Graph I shows the viscosity reduction of EBECRYL® 294/25 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.

• 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.
