• Reactive diluents are preferred to reduce solvent emissions.

Precautions:

• Refer to the Safety Data Sheet (SDS) for information on identified hazards, recommended personal protective equipment, and procedures.
• Avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids.
• Store in suitable containers and avoid oxygen-free atmospheres. Use dry air to displace material removed from the container. Keep the container tightly closed and 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.
• Wash thoroughly after handling.

EBECRYL® 8411 should be handled and stored with care to ensure its stability and effectiveness in various applications.
