EBECRYL® 221

EBECRYL® 221 is characterized by

• Light color
• Excellent cure response

UV/EB cured products based on EBECRYL® 221 are characterized by the following performance properties:

• High hardness and scratch resistance
• High solvent resistance
• High gloss
• Fast cure speed

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

Formulated UV/EB curable products containing EBECRYL® 221 may be applied by lithographic, screen, gravure, direct or reverse roll, and curtain coating methods.
EBECRYL® 221 is recommended for use in:

• Wood coatings and fillers
• Lithographic inks
• Scratch resistant coatings on plastic
• Improving cure speed, solvent resistance and gloss

EBECRYL® 221 can be diluted with reactive monomers such as 1,6- hexanediol diacrylate HDDA) product of allnex , trimethylolpropane triacrylate (TMPTA)(1) and trimethylolpropane ethoxy triacrylate (EBECRYL® 160) product of allnex . The specific reactive diluent(s) used will influence performance properties such as hardness and flexibility.

The toxicological properties of this material have not been fully determined. Products of this type can be expected to be eye and skin irritant and have the potential to cause sensitization or other allergic responses. Appropriate precautions should be taken to avoid eye and skin contact and to avoid inhalation of the aerosols or vapors.

• Care should be taken not to expose radiation curable products to temperatures exceeding 40°C for prolonged periods or to direct sunlight. This might cause uncontrollable polymerization of the product with generation of heat.
• Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers.
• Do not store this material under an oxygen free atmosphere. Use dry air to displace material removed from the container. This material should not be stored for more than 2 years.
