EBECRYL® 8296

EBECRYL® 8296 is an aliphatic urethane acrylate designed for use in applications requiring haptic properties, commonly known as "soft touch." When cured via exposure to ultraviolet light (UV) or electron beam (EB), films of EBECRYL® 8296 exhibit softness, flexibility, and resistance to yellowing while maintaining a high surface tack. It typically develops a semi-crystalline aspect upon storage.

Here are the key details about EBECRYL® 8296:

Type: Aliphatic urethane acrylate

Special Properties and Use:

• Designed for applications requiring haptic properties, providing a soft touch sensation.
• Films cured with EBECRYL® 8296 are soft, flexible, and resistant to yellowing, with a high surface tack.

Performance Highlights:

• Light color
• Semi-crystalline state

Suggested Applications:

• In-mold decoration
• Coatings for plastics
• Automotive coatings
• Screen inks
• Flexographic inks
• Exterior durable coatings

Viscosity Reduction:

• Can be formulated with reactive diluents such as dipropylene glycol diacrylate (DPGDA), 1,6-hexanediol diacrylate (HDDA), and tripropylene glycol diacrylate (TPGDA) to reduce viscosity.
• Reactive diluents are preferred to avoid solvent emissions and ensure 100% conversion during UV exposure.

Typical Physical Properties:

• Density: 1.10 g/cm³ at 25°C
• Functionality, theoretical: 3.0
• Melting point: 53°C
• Oligomer: 100% by weight

Typical Cured Properties:

• Tensile strength: 300 psi (2.1 MPa)
• Elongation at break: 18%
• Young’s modulus: 2000 psi (14 MPa)
• Glass transition temperature: -1°C

Precautions:

• Follow safety guidelines outlined in the Safety Data Sheet (SDS) before using EBECRYL® 8296.

Storage and Handling:

• Store in appropriate containers and conditions to prevent uncontrollable polymerization.
• Avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids.

EBECRYL® 8296 offers excellent properties for applications where a soft touch sensation is desired, such as coatings for various substrates and inks for printing. Proper storage and handling are essential to maintain its effectiveness and safety.
