EBECRYL® 1710

EBECRYL® 1710 is a diluted acrylic polymer that consists of 60% by weight of the reactive diluent 1,6-hexanediol diacrylate (HDDA). It is primarily used as a modifying oligomer in formulations for ultraviolet light (UV) or electron beam (EB) curing processes, aimed at enhancing film properties such as adhesion and lay-down. Here's a breakdown of its features, specifications, and precautions as outlined in the technical datasheet:

Performance Highlights:

• Moderate viscosity and low color.
• UV/EB cured products containing EBECRYL® 1710 demonstrate improved adhesion, reduced film defects, and good exterior durability.

Suggested Applications:

• Suitable for offset and screen printing applications, as well as various coating methods such as direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, and immersion coating.
• Recommended for use in silk screen inks and coatings on plastics like polycarbonate, polyester, polyolefins, and PVC.
• Typical use level ranges from 20% to 60% by weight of the total formulation, showing excellent compatibility with most acrylates.

Specifications:

• Appearance: Clear liquid.
• Color, Gardner: Maximum 1.
• Viscosity at 25°C: Ranging from 24050 to 27950 mPa.s.

Typical Physical Properties:

• Density at 25°C: 1.07 g/cm³.
• HDDA, % by weight: 60.

Typical Cured Properties:

• Tensile strength: 6440 psi (44 MPa).
• Elongation at break: 3.6%.
• Young’s modulus: 315000 psi (2172 MPa).
• Glass transition temperature: 82°C.

Precautions:

• Before using EBECRYL® 1710, refer to the Safety Data Sheet (SDS) for information on identified hazards and recommended personal protective equipment and procedures.
• Store in appropriate containers and conditions to avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids, which may cause uncontrollable polymerization.
• Handle with adequate ventilation and follow proper handling and storage protocols outlined in the SDS.

Overall, EBECRYL® 1710 is designed to enhance the performance of UV/EB curable formulations, particularly in applications where improved adhesion and film properties are desired.
