Features Of IGM Omnirad 4817 Photoinitiator

  1. High reactivity under UV and LED light sources (365–405 nm), enabling fast cure speeds in demanding production environments.

  2. Low migration and excellent extractable residue profile, supporting compliance with stringent food-contact and medical device regulations.

  3. Good solubility in common acrylate monomers and oligomers, ensuring homogeneous formulation without crystallization or phase separation.

  4. Reduced yellowing tendency compared to conventional Type II photoinitiators, delivering superior clarity in transparent and white coatings.

  5. Thermal stability up to 120 °C during storage and handling, minimizing premature decomposition and extending shelf life.

Typical Applications Of IGM Omnirad 4817 Photoinitiator

  1. UV-curable inkjet inks for packaging, décor, and industrial printing.

  2. Clear and pigmented UV coatings for wood, plastic, and metal substrates.

  3. Adhesives and laminating systems requiring low odor and high bond strength.

  4. 3D printing resins (SLA/DLP) where low shrinkage and high resolution are critical.

  5. Medical device coatings and components compliant with ISO 10993 and USP Class VI requirements.
