IGM Omnipol CPTX is a high-efficiency Type II UV photoinitiator in the Omnipol series, designed for radical polymerization of unsaturated oligomers and sensitization of cationic systems. Benzene-free and low-odor, it needs to be used with tertiary amine synergists, which can efficiently initiate UV radical polymerization of acrylates and other oligomers. It can also be used as a sensitizer for iodonium salts in cationic solids, suitable for harsh scenarios such as printing inks and can coatings
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
