EBECRYL® 3203

EBECRYL® 3203 is a low viscosity modified Bisphenol-A based epoxy acrylate oligomer primarily used for the preparation of high pigment loading pigment pastes, especially for black and white inorganic pigments and fillers. Here's a summary of its features and suggested applications:

Introduction:

• EBECRYL® 3203 is a modified Bisphenol-A based epoxy acrylate oligomer with low viscosity.
• It provides exceptional pigment wetting properties, particularly for black and white inorganic pigments and fillers.
• This material offers a fast cure response when formulated with other oligomers and cured via ultraviolet light (UV) or electron beam (EB).

Performance Highlights:

• Low viscosity.
• Excellent pigment wetting properties.
• Good cure response in UV/EB curable formulations.

Suggested Applications:

• High loading pigment paste formulations prepared with EBECRYL® 3203 are utilized in the production of UV/EB curable inks, primarily in flexography, gravure, and UV ink-jet applications.
• The ability to produce highly loaded pigment pastes allows ink formulators more flexibility by using less pigment paste to achieve a given optical density.

Storage and Handling:

• 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).
• Avoid procedures that remove or displace oxygen from the material.
• Use with adequate ventilation.
• Follow the recommended storage temperature range provided in the SDS.

EBECRYL® 3203 offers significant advantages in pigment dispersion and cure response for UV/EB curable ink formulations, particularly in applications where high pigment loading is required.
