EBECRYL® 8311

EBECRYL® 8311 is an aliphatic urethane acrylate nanocomposite designed for use in ultraviolet (UV) light or electron beam (EB) curable coatings. Here's a breakdown of its characteristics and applications:

Introduction:

• EBECRYL® 8311 is an aliphatic urethane acrylate nanocomposite with low viscosity and high reactivity.
• Films of EBECRYL® 8311 display excellent weatherability, outstanding hardness, chemical resistance, and scratch and abrasion resistance, with very low haze development after abrasion.

Performance Highlights:

• Good compatibility and stability.
• Low viscosity and light color.
• Excellent reactivity.
• Outstanding hardness.
• Low haze development after abrasion.
• No agglomeration or sedimentation.
• PETA free.

Suggested Applications:

• Suitable for coatings requiring high scratch/abrasion resistance and improved adhesion.
• Ideal for coatings requiring low development after abrasion resistance.
• Can be used as a modifying oligomer to increase cure speed, solvent resistance, and abrasion resistance.

Specifications:

• Appearance: Clear liquid
• Color, Gardner max: 2
• Viscosity at 25°C: 7000 - 14000 mPa.s

Typical Cured Properties:

• Tensile strength: 5200 psi (36 MPa)
• Elongation at break: 2.5%
• Young’s modulus: 500000 psi (3448 MPa)

Abrasion Resistance:

• EBECRYL® 8311 improves abrasion resistance, as demonstrated by a decrease in haze with increasing amounts of EBECRYL® 8311 in a coating.

Precautions:

• Before using EBECRYL® 8311, refer to the Safety Data Sheet (SDS) for hazard information and recommended protective measures.

Storage and Handling:

• Store EBECRYL® 8311 away from high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids to prevent uncontrollable polymerization.
• Use appropriate containers and ensure adequate ventilation during handling.

EBECRYL® 8311 offers a versatile solution for UV/EB curable coatings requiring high performance in scratch and abrasion resistance, hardness, and weatherability.
