EBECRYL® 3701-20T

• EBECRYL®3701-20T is characterized by:
  • Fast UV/EB cure response
  • Reduced viscosity
  • Easier handling
• UV/EB cured products based on EBECRYL®3701-20T are characterized by the following performance properties:
  • High gloss
  • Superior chemical resistance
  • Abrasion resistance
• The final 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®3701-20T 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 offset, screen and flexographic printing.
• EBECRYL®3701-20T is recommended for use in:
  • Clear coatings for paper
  • Topcoats for wood
  • Screen and flexographic ink vehicles
  • Metal decorating ink and clear coatings
  • Clear coatings for rigid and flexible plastics
  • Laminating adhesives

GRAPH I:EBECRYL®3701-20T - VISCOSITY REDUCTION WITH REACTIVE DILUENTS

GRAPH II:EBECRYL®3701-20T - VISCOSITY VS. TEMPERATURE

• Graph I shows the viscosity reduction of EBECRYL®3701-20T with 1,6-hexanediol diacrylate (HDDA)¹, isobornyl acrylate (IBOA)¹, trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA)¹.
• 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 avoiding solvent emissions.
• The specific reactive diluents used will influence performance properties such as hardness and flexibility.
• Graph II illustrates the change in viscosity of EBECRYL 3701-20T with increasing temperature.
• ¹ Product of allnex

• 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.
