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
High-efficiency Type I initiation - α-hydroxy ketone structure, excellent reactivity, high initiation efficiency and fast curing speed
Excellent non-yellowing performance - No yellowing after curing, not easy to lose light after long-term use, suitable for high appearance scenarios
Low oxygen inhibition sensitivity - Low sensitivity to oxygen inhibition, good surface curing effect, no complex deoxygenation process needed
Low odor and low volatility - Large molecular weight, low volatility, low odor of itself and photolysis products, suitable for sensitive scenarios
Strong synergistic adaptability - Can be used alone or combined with other photoinitiators, absorption spectrum can be optimized, strong versatility
UV ink field - Offset, screen, flexo and inkjet inks, fast curing, high printing precision, no yellowing impact
Thin coating field - Overprint varnishes and other thin coatings, uniform curing, improving coating gloss and wear resistance
Wood coating field - Wood UV varnishes/topcoats, non-yellowing and light-retaining, improving decorative texture and durability
Transparent coating field - Various transparent UV coatings, high transparency after curing, no obvious residual odor
Composite system field - Combined with other photoinitiators, suitable for semi-opaque systems, more excellent curing performance
