EBECRYL® 1258

Formulated UV/EB curable products containing EBECRYL® 1258 may be applied via brush, roller, 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® 1258 is recommended for use:

• In applications that must meet regulations for tin, heavy metal, and quinone content
• On hard to adhere to substrates
• In metal coatings
• In plastic coatings
• In exterior durable coatings

EBECRYL® 1258 - Viscosity reduction with reactive diluents:

• Graph I shows the viscosity reduction of EBECRYL® 1258 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.

Avoid contact with eyes and skin. Direct contact with EBECRYL® 1258 may cause moderate eye and skin irritation. Contact with skin may cause a cross-allergic reaction in persons already sensitized to acrylate materials. Wash thoroughly after handling. Keep container tightly closed. Use with adequate ventilation.

• The recommended storage temperature range for EBECRYL® 1258 is 4°C to 40°C (39°F to 104°F). EBECRYL® 1258 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.
