• Light color
• Fast cure response
• Low irritancy
• Improved pigment wetting

UV/EB cured products based on EBECRYL®®640/20 TO are characterized by the following performance properties :

• High surface hardness
• High gloss
• Excellent solvent resistance
• Good water resistance

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®®640/20 TO may be applied by lithographic, screen, gravure, direct or reverse roll, and curtain coating methods. EBECRYL®®640/20 TO is recommended for use in :

• Overprint varnishes
• Lithographic and screen inks
• Coatings for paper, paperboard, wood, chipboard and rigid plastics
• Paper upgrading
• Fast cure response
