EBECRYL® 570

EBECRYL® 570 is a chlorine-free and tin-free polyester resin diluted with the reactive diluent EBECRYL® 40. It's designed for low migration and low odor inks and coatings, offering good adhesion to plastic substrates and films cured by ultraviolet light (UV) or electron beam (EB). Here's a summary of its features, applications, and precautions:

Introduction:

• EBECRYL® 570 is a chlorine-free and tin-free polyester resin suitable for low migration and low odor inks and coatings.
• It provides good adhesion to plastic substrates and films cured by UV or EB and is compliant with the Nestle list on acrylates.

Performance Highlights:

• Light color
• Good adhesion to plastic substrates such as PE, PP, PET, PC, and PVC
• Low odor

Suggested Applications:

• Sensitive applications such as food packaging (Compliant with the Nestle list on acrylates)
• Flexo inks and Over Print Varnishes for plastic and metallic substrates
• In-mold labels

• Acid value: max. 14 - 28 mg KOH/g
• Appearance: Clear liquid
• Color: max. 200 Apha
• Residual solvent (toluene): < 100 ppm
• Viscosity at 25°C: 40000 - 60000 mPa.s

Typical Properties:

• Density at 25°C: 1.2 g/cm³
• Hydroxyl value: ~40 mg KOH/g
• Resin content: 50% by weight
• EBECRYL® 40 content: 50% by weight

Viscosity Reduction:

• EBECRYL® 570 can be further diluted with EBECRYL® 40 or other reactive monomers such as HDDA, TPGDA, OTA-480, or TMPTA.
• Reactive diluents are preferred for viscosity reduction as they are fully converted during UV/EB exposure.

Precautions:

• Refer to the Safety Data Sheet (SDS) for hazard information and recommended protective measures.
• Store away from high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids.
• Use appropriate containers and avoid oxygen displacement.
• Ensure adequate ventilation during handling.

EBECRYL® 570 offers a versatile solution for various ink and coating applications, especially in sensitive areas such as food packaging, with attention to safety and proper handling procedures.
