EBECRYL® 3702

EBECRYL® 3702 is a fatty acid modified bisphenol A epoxy diacrylate primarily used in UV and EB cured coatings. Here's a breakdown of its technical datasheet:

Introduction:

• EBECRYL® 3702 is a fatty acid modified bisphenol A epoxy diacrylate known for its outstanding flow and leveling properties, as well as excellent pigment wetting properties.
• Cured films exhibit high gloss, improved water resistance, and good chemical resistance.

Performance Highlights:

• Low odor, excellent pigment wetting, and good flow and leveling.
• UV/EB cured products have good chemical and water resistance, high gloss, and greater flexibility than standard bisphenol A epoxy acrylates.

Suggested Applications:

• Suitable for clear coatings for paper, overprint varnishes, lithographic ink vehicles, metal decorating inks and clear coatings, screen ink vehicles, and coatings for rigid and flexible plastics.

Viscosity Reduction:

• Can be reduced with reactive diluents such as 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA).

Storage and Handling:

• Avoid exposure to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids to prevent uncontrollable polymerization.
• Store in appropriate containers (stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers) and avoid storing under an oxygen-free atmosphere.
• Use with adequate ventilation and follow recommended storage temperature ranges.
