IGM Omnirad 248 is a high-efficiency Type I free radical UV photoinitiator of α-amino ketone in the Omnirad series, designed for UV radiation curing systems. It can quickly decompose to generate free radicals when exposed to UV light, efficiently initiating the polymerization of diluted acrylates and acrylate oligomers. With wide absorption in the UV-A region and outstanding reactivity in colored systems
High-efficiency Type II initiation - Synergizes with tertiary amine synergists, high radical initiation efficiency and stable curing reaction
Dual-function adaptation - Has both photoinitiation and sensitization effects, can sensitize iodonium salts in cationic solids
Benzene-free low-odor environmental protection - Benzene-free formula, extremely low odor, meets high-end environmental compliance, suitable for sensitive scenarios
Multi-system compatibility - Suitable for acrylates and other unsaturated oligomers, compatible with cationic iodonium salt systems
Easy processing adaptability - Easy to add and mix, no complex process adjustment, suitable for large-scale productio
Cationic printing inks - Various cationic printing inks and overprint varnishes, fast curing, high printing precision
Can coatings field - Can UV coatings, high solvent and corrosion resistance, suitable for food contact-related packaging
Coil coatings field - UV-curable coil coatings, low shrinkage, strong adhesion, suitable for continuous production
Pharmaceutical packaging inks - UV inks for pharmaceutical packaging, benzene-free and low-odor, meeting strict compliance requirements
Cationic system sensitization - Sensitization of iodonium salts in cationic solids, improving cationic curing efficiency
