EBECRYL® 600/30 OT

EBECRYL® 600/30 OT is a urethane acrylate oligomer designed for UV (ultraviolet) and EB (electron beam) curing applications. Here's a breakdown of its key features and applications:

Introduction: It's a diacrylate ester of bisphenol A epoxy resin diluted with 30% of oligotriacrylate (OTA 480). This resin is known for its low odor, light color, low irritancy, and fast cure response. When cured by exposure to UV or EB, films of EBECRYL® 600/30 OT exhibit high surface hardness, gloss, and excellent solvent resistance typical of epoxy resins.

Performance Highlights:

• Fast cure response
• Low irritancy
• Light color
• High surface hardness
• High gloss
• Excellent solvent resistance
• Low residual odor

Suggested Applications: Formulated UV/EB curable products containing EBECRYL® 600/30 OT are suitable for various applications including:

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

Typical Values:

• Viscosity at 25°C: Approximately 19000 mPa.s
• Colour (Gardner): Maximum 2
• Acid value (mg KOH/g): Maximum 2

Physical Properties:

• Density: 1.13 g/cm3
• Molecular weight: Theoretical value of 500
• Functionality: Theoretical value of 2

Viscosity Reduction: EBECRYL® 600/30 OT can be diluted with various reactive monomers such as oligotriacrylate, 1,6-hexanediol diacrylate, trimethylolpropane triacrylate, tripropyleneglycol diacrylate, and octyl/decyl acrylate. The choice of diluent(s) will impact properties like hardness and flexibility.

Storage and Handling:

• Avoid exposing radiation-curable products to temperatures exceeding 40°C or direct sunlight for extended periods to prevent uncontrollable polymerization.
• Store in appropriate containers (stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers).
• Do not store under an oxygen-free atmosphere.
• Use dry air to displace material removed from the container.
• Shelf life: Not more than 2 years after the production date.

Precautions:

• Toxicological properties are not fully determined, but products of this type can be eye and skin irritants and may cause sensitization or allergic responses.
• Take appropriate precautions to avoid contact with eyes, skin, and inhalation of aerosols or vapors.
• Consult the Safety Data Sheet for detailed handling procedures and protective equipment.

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

Overall, EBECRYL® 600/30 OT is a versatile material suitable for various UV/EB curable coating applications, offering fast curing, low odor, and excellent performance properties.
