EBECRYL® 40

EBECRYL® 40 is a tetrafunctional polyether acrylate characterized by its low viscosity, mild odor, and light color. It is primarily used as a diluting reactive oligomer in ultraviolet light (UV) and electron beam (EB) cured coatings and inks. Here's a breakdown of its features and suggested applications:

Introduction:

• EBECRYL® 40 is a part of the ECOWISE™ CHOICE product range for selected applications, emphasizing its eco-friendly attributes.
• It offers fast cure response when formulated with acrylate oligomers, enhancing the hardness and solvent resistance of cured inks and coatings.
• Recommended for lithographic offset inks, overprint varnishes, and paper upgrading.

Performance Highlights:

• Light color.
• Low viscosity.
• Low odor.
• Good cure response.

Performance Properties of UV/EB Cured Products:

• High surface hardness.
• Good solvent resistance.
• Low residual odor.
• Reduced shrinkage.

Suggested Applications:

• Commonly used as a diluting reactive oligomer in UV/EB cured coatings and inks, typically ranging from 10% to 50% depending on the application.
• Particularly effective in lithographic inks and varnishes for adjusting viscosity while maintaining or improving cure response and physical properties.
• Recommended for offset inks, overprint varnishes, coatings on paper and plastics, paper upgrading, and reducing curl on flexible substrates.
