EBECRYL® P39 is a polymeric benzophenone derivative, and functions as a photosensitizer in hydrogen abstraction-type radical photoinitiator systems. It is specifically designed for formulating UV coatings that exhibit minimal or no odor after curing. This product is well-suited for applications like overprint varnishes, where achieving low residual odor in the cured coatings is essential. The physical form of EBECRYL® P39 is a liquid.

Storage & Handling

Storage and Handling
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. See the SDS for the recommended storage temperature range for EBECRYL P39.
