EBECRYL® 4101

EBECRYL® 4101 is an undiluted aliphatic urethane acrylate designed for coatings on various surfaces such as wood, cork, furniture, paper, parquet, and film. Here's a breakdown of its technical datasheet:

• Introduction: EBECRYL® 4101 is free from intentionally added organic tin compounds and is suitable for UV/EB cured coatings.
• Performance Highlights:
  • UV/EB cured coatings based on EBECRYL® 4101 exhibit high flexibility and good chemical and mechanical resistance properties. However, the actual properties also depend on other formulation components.
• Suggested Applications:
  • EBECRYL® 4101 is used in the formulation of UV/EB energy curable coatings applied by roller coating, spraying, and curtain coating on wood, cork, furniture, paper, parquet, and film.
• Formulating:
  • Adjusting the coating to application viscosity can be done using standard reactive diluents such as dipropylene glycol diacrylate (DPGDA), 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), and trimethylolpropane triacrylate (TMPTA), or solvents such as butyl acetate.
  • Compatibility with reactive diluents and solvents must be tested in each case.
  • UV curing requires the addition of standard commercial photoinitiators at typical levels of 4 - 6%. In EB curing, a low oxygen atmosphere is necessary to avoid surface inhibition.
  • Lower gloss coatings can be achieved using standard matting agents, but sedimentation should be considered to prevent premature gelling.
• Typical Physical Properties:
  • Acid number (mg KOH/g): ≤ 2
  • Color (Apha): ≤ 200
  • Density (g/cm³ at 20°C): 1.13
  • Flash point (°C): > 100
  • Functionality: 3.0
  • Hydroxyl content (%): ~0.3
  • Viscosity (23°C, mPa.s): ~7500
• Precautions:
  • Follow the Safety Data Sheet (SDS) for handling precautions.
• 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 and avoid procedures that remove or displace oxygen from the material.
  • Recommended storage temperature range is provided in the SDS.
