Features Of IGM Omnirad 184D Photoinitiator

  1. High reactivity under UV-A and visible light (365–405 nm), enabling rapid curing in low-energy systems.

  2. Excellent solubility in common acrylate monomers and oligomers, ensuring homogeneous formulation stability.

  3. Low yellowing tendency post-cure, supporting high-gloss and optically clear final coatings and inks.

  4. Good thermal stability up to 80 °C during storage and handling, minimizing premature decomposition.

  5. Non-migrating molecular structure, contributing to improved regulatory compliance in sensitive applications.

Typical Applications Of IGM Omnirad 184D Photoinitiator

  1. UV-curable wood coatings for furniture and flooring.

  2. Industrial offset and flexographic printing inks.

  3. Electronic encapsulants and conformal coatings.

  4. Optical adhesives and lens bonding formulations.

  5. 3D printing resins for stereolithography (SLA) and digital light processing (DLP).
