Features Of IGM Omnirad 432 Photoinitiator

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

  2. Excellent surface cure performance with low oxygen inhibition, resulting in tack-free finishes even in ambient air conditions.

  3. Good solubility in common acrylate monomers and oligomers, facilitating homogeneous formulation without precipitation or haze.

  4. Low volatility and minimal odor, supporting safer handling and improved workplace compliance with industrial hygiene standards.

  5. Thermal stability up to 120 °C, allowing compatibility with heat-assisted curing processes and extended shelf life.

Typical Applications Of IGM Omnirad 432 Photoinitiator

  1. UV-curable coatings for wood, plastic, and metal substrates in industrial finishing lines.

  2. LED-curable inks for digital inkjet printing on flexible packaging and labels.

  3. Optical adhesives and laminating resins used in display assembly and touch panel manufacturing.

  4. 3D printing resins for stereolithography (SLA) and digital light processing (DLP) systems requiring high resolution and depth control.

  5. Electronics encapsulants and conformal coatings where rapid through-cure and low shrinkage are critical.
