EBECRYL® 230

EBECRYL® 230 is an aliphatic urethane diacrylate that offers several characteristics making it suitable for various applications. Here's an overview:

Introduction:

• EBECRYL® 230 is characterized by its light color and low viscosity.
• It cures via exposure to ultraviolet light (UV) or electron beam (EB), resulting in soft and flexible films that are resistant to yellowing.
• Often used as a modifier to improve the flexibility of finished formulations.

Performance Highlights:

• Light color and low viscosity.
• UV/EB cured products containing EBECRYL® 230 offer improved flexibility and are non-yellowing.

Suggested Applications:

• Suitable for use in formulated UV/EB curable products applied via various methods such as 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 and screen printing.
• Recommended for:
  • Increasing flexibility of UV/EB cured coatings and inks.
  • Laminating adhesives.
  • Coatings for plastic and metal.
  • Lithographic and screen inks.

Specifications:

• Appearance: Clear liquid.
• Color: Maximum 50 APHA.
• Viscosity at 25°C: 30,000 - 60,000 mPa.s.

Typical Physical Properties:

• Density at 25°C: 1.08 g/cm³.
• Functionality (theoretical): 2.
• Oligomer content: 100% by weight.

Typical Cured Properties:

• Tensile strength: 450 psi (3.0 MPa).
• Elongation at break: 127%.
• Young's modulus: 580 psi (4.0 MPa).
• Glass transition temperature: -39°C.

Viscosity Reduction:

• Reactive diluents such as 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA) can be used to reduce viscosity. Reactive diluents are preferred to reduce solvent emissions.

Precautions:

• Follow safety guidelines outlined in the Safety Data Sheet (SDS).
• Store in appropriate containers away from high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids.
• Adequate ventilation is recommended during handling.
• Refer to the SDS for recommended storage temperature range.

EBECRYL® 230 offers versatility and performance suitable for various coating and ink applications, providing flexibility and resistance to yellowing. Proper handling and storage are essential to maintain its properties.
