IGM Omnirad 127 D UV Photoinitiator固体

IGM Omnirad 127 D is a high-efficiency non-yellowing α-hydroxy ketone Type I free radical UV photoinitiator in the Omnirad series, designed for UV radiation curing systems. As a high-performance Type I initiator, it can be combined with mono or multifunctional monomers to efficiently initiate the photopolymerization of acrylates and other unsaturated prepolymers. With low sensitivity to oxygen inhibition, low volatility and low odor after curing, it is suitable for pigmented and transparent systems

Features Of IGM Omnirad 127 D UV Photoinitiator

  1. High-efficiency Type I initiation - α-hydroxy ketone structure, excellent reactivity, high initiation efficiency and fast curing speed

  2. Excellent non-yellowing performance - No yellowing after curing, not easy to lose light after long-term use, suitable for high appearance scenarios

  3. Low oxygen inhibition sensitivity - Low sensitivity to oxygen inhibition, good surface curing effect, no complex deoxygenation process needed

  4. Low odor and low volatility - Large molecular weight, low volatility, low odor of itself and photolysis products, suitable for sensitive scenarios

  5. Strong synergistic adaptability - Can be used alone or combined with other photoinitiators, absorption spectrum can be optimized, strong versatility

Typical Applications Of IGM Omnirad 127 D UV Photoinitiator

  1. UV ink field - Offset, screen, flexo and inkjet inks, fast curing, high printing precision, no yellowing impact

  2. Thin coating field - Overprint varnishes and other thin coatings, uniform curing, improving coating gloss and wear resistance

  3. Wood coating field - Wood UV varnishes/topcoats, non-yellowing and light-retaining, improving decorative texture and durability

  4. Transparent coating field - Various transparent UV coatings, high transparency after curing, no obvious residual odor

  5. Composite system field - Combined with other photoinitiators, suitable for semi-opaque systems, more excellent curing performance
