EBECRYL® 6040

EBECRYL® 6040 is an epoxy acrylate oligomer designed for UV and EB (electron beam) curing applications. Here's a breakdown of its technical datasheet:

Introduction: EBECRYL® 6040 is a modified diacrylate ester of bisphenol A epoxy resin characterized by its low odor, light color, low irritancy, and fast cure response. It forms films with high surface hardness, gloss, and excellent solvent resistance typical of epoxy resins. It is particularly useful in overprint varnishes.

Performance Data:

• Light color
• Fast cure response
• Low irritancy
• UV/EB cured products exhibit:
  • High surface hardness
  • High gloss
  • Excellent solvent resistance
  • Low residual odor

Suggested Applications:

• Screen inks and varnishes
• Overprint varnishes
• Coatings on wood, cardboard, chipboard, paper, and rigid plastics
• Coatings where low residual odor is required

Typical Value:

• Höppler viscosity at 25°C: ± 25000 mPa.s
• Gardner color: max. 2
• Acid value: max. 2 mg KOH/g
• Density: 1.14 g/cm³
• Theoretical molecular weight: 500
• Theoretical functionality: 2

Viscosity Reduction: EBECRYL® 6040 can be diluted with reactive monomers such as oligotriacrylate, 1,6-hexanediol diacrylate, tripropyleneglycol diacrylate, trimethylolpropane triacrylate, and octyl/decyl acrylate.

Storage and Handling:

• Avoid exposing to temperatures exceeding 40°C or direct sunlight to prevent uncontrollable polymerization.
• Use stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers.
• Store in a dry atmosphere.
• Do not store for more than 2 years.

Precaution:

• Products of this type can be eye and skin irritants.
• Appropriate precautions should be taken to avoid contact and inhalation.
• Consult the Safety Data Sheet for handling procedures and protective equipment.

Statutory Labeling: Refer to the Safety Data Sheet for statutory labeling information.

EBECRYL® 6040 offers a range of properties suitable for various UV/EB curing applications, providing high-performance coatings with desirable characteristics such as hardness, gloss, and solvent resistance.
