EBECRYL® P39

EBECRYL® P39 is a polymeric benzophenone derivative that functions as the photosensitizer in hydrogen abstraction type radical photoinitiator systems. EBECRYL® P39 has been designed for use in the formulation of UV coatings that exhibit little or no odor after curing. Recommended levels are from 8 to 10% based on total formulation. EBECRYL® P39 should be used in combination with amine co-initiators such as EBECRYL® P115 or EBECRYL® 7100, or with amine modified acrylate resins. EBECRYL® P39 is a polymer preparation manufactured in the European Union with (pre)registered monomers/reactants and REACH compliant.

Performance Highlights

EBECRYL® P39 is characterized by:

  • Pourable liquid

UV/EB cured products based on EBECRYL® P39 are characterized by the following performance properties:

  • Low odor
  • Increased flexibility

The actual properties of UV/EB cured products also depend on the selection of the other formulation components, such as reactive diluent(s), additives and photoinitiators.

Storage & Handling

Storage Conditions

Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids. This might cause uncontrollable polymerization of the product with the generation of heat. Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers. Procedures that remove or displace oxygen from the material should be avoided. Do not store this material under an oxygen free atmosphere. Dry air is recommended to displace material removed from the container. Wash thoroughly after handling. Keep container tightly closed. Use with adequate ventilation.
