EBECRYL® 210

EBECRYL® 210 is an aromatic urethane diacrylate offered by Allnex. Here are the key details from the technical datasheet:

Introduction:

• EBECRYL® 210 is an aromatic urethane diacrylate designed for UV and EB curing systems. It produces films with good flexibility, low color, and excellent adhesion to various substrates.

Performance Highlights:

• Light color
• Low odor
• Good flexibility
• Reduced glass transition temperature (Tg)

Suggested Applications:

• Coatings on rigid and flexible plastics
• Wood coatings
• Screen inks
• Low gloss coatings
• Conformal coatings
• Modification of oligomers to increase flexibility

Specifications:

• Appearance: Clear liquid
• Color, Gardner: Max. 2
• Viscosity (60°C): 3600 - 4600 mPa.s

Typical Physical Properties:

• Density (g/ml at 25°C): 1.11
• Functionality, theoretical: 2
• NCO, %: < 0.2
• Oligomer, % by weight: 100

Typical Cured Properties:

• Tensile strength: 2218 psi (15.3 MPa)
• Elongation at break: 64%
• Glass transition temperature (Tg): -19°C

Viscosity Reduction:

• Reactive diluents like octyl/decyl acrylate, propoxylated glycerol triacrylate, trimethylolpropane triacrylate, and tripropylene glycol diacrylate can reduce the viscosity of EBECRYL® 210. Reactive diluents are preferred as they become part of the coating or ink during UV/EB exposure, reducing solvent emissions.

Precautions:

• Follow safety guidelines provided in the Safety Data Sheet (SDS).
• Store in appropriate containers away from high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids.
• Use with adequate ventilation.

Storage and Handling:

• Store in stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers.
• Avoid procedures that remove or displace oxygen from the material.
• Do not store under an oxygen-free atmosphere.
• Recommended storage temperature range is available in the SDS.

In summary, EBECRYL® 210 offers versatility in UV and EB curing systems, providing good flexibility, adhesion, and low color. Proper handling and storage are essential to maintain its properties.
