EBECRYL® 5848

EBECRYL® 5848 is an epoxidized soya oil acrylate, primarily used as a modifier in ultraviolet light (UV) or electron beam (EB) energy curable inks and coatings. Here's a detailed overview:

Introduction:

• EBECRYL® 5848 is based partially on renewable resources, making it environmentally friendly.
• It enhances flow, leveling, and pigment wetting in UV or EB energy curable inks and coatings.
• When used as a modifier, it can improve adhesion and flexibility in coatings on paper and metal substrates.

Performance Highlights:

• Approximately 62% renewable content.
• Moderate viscosity.
• Good pigment wetting.
• Suitable hydrophilic-lipophilic balance for lithography.

Suggested Applications:

• It can be applied via various methods including direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, immersion, and spin coating methods.
• Recommended for overprint varnishes for paper, lithographic ink vehicles, metal decorating and protective coatings, screen ink vehicles, and pigmented coatings for wood.

Specifications:

• Appearance: Clear liquid.
• Color, Gardner max: 10.

Typical Physical Properties:

• Acid value, mg KOH/g: ≅9.6
• Epoxy content, %: ≅0.14
• Density, g/cm³ at 25°C: 1.03
• Functionality, theoretical: 3 - 4
• Oligomer, % by weight: > 97.5
• Viscosity, 25°C, mPa.s: ≅20000

Precautions:

• Before usage, refer to the Safety Data Sheet (SDS) for information on hazards and recommended personal protective equipment.
• Avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids to prevent uncontrollable polymerization.
• Store and handle in suitable containers (stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers) to prevent polymerization.
• Avoid procedures that remove or displace oxygen from the material.
• Use with adequate ventilation and wash thoroughly after handling.

Storage and Handling:

• Store according to the recommended temperature range provided in the SDS.
• Keep the container tightly closed and avoid storing under an oxygen-free atmosphere.
• Dry air is recommended to displace material removed from the container.

EBECRYL® 5848 offers a range of benefits for UV or EB curable coatings and inks, including improved adhesion, flexibility, and surface appearance. It's designed for various printing and coating applications while considering environmental concerns and safety precautions during handling and storage.
