IGM Omnipol 9220 UV Photoinitiator

IGM Omnipol 9220 is a high-performance monomer-diluted polymeric Type I UV photoinitiator in the Omnipol series, designed for high-end UV curing systems requiring low migration and low odor. Based on piperazine-based aminoalkyl benzophenone, it features high reactivity and excellent processability after monomer dilution. Its high purity makes it preferred in the food packaging industry, with low fragment release after curing and ready-to-use directly.

Features Of IGM Omnipol 9220 UV Photoinitiator

  1. High reactivity fast curing - Rapid reaction under UV light, high polymerization efficiency, shortens production cycle

  2. Low migration and odor - Ultra-low migration rate, light odor, low fragment release after curing, meets environmental compliance

  3. Monomer diluted easy processing - Pre-diluted formula, moderate viscosity, no extra treatment, ready to add directly

  4. Excellent system compatibility - Compatible with most UV curing systems, uniform mixing, suitable for various formulations

  5. High purity low residue - Excellent purity, low residue, suitable for sensitive applications like food packaging
