IGM Omnipol CPTX UV Photoinitiator固体

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

Features Of IGM Omnipol CPTX UV Photoinitiator

  1. High-efficiency Type II initiation - Synergizes with tertiary amine synergists, high radical initiation efficiency and stable curing reaction

  2. Dual-function adaptation - Has both photoinitiation and sensitization effects, can sensitize iodonium salts in cationic solids

  3. Benzene-free low-odor environmental protection - Benzene-free formula, extremely low odor, meets high-end environmental compliance, suitable for sensitive scenarios

  4. Multi-system compatibility - Suitable for acrylates and other unsaturated oligomers, compatible with cationic iodonium salt systems

  5. Easy processing adaptability - Easy to add and mix, no complex process adjustment, suitable for large-scale productio

Typical Applications Of IGM Omnipol CPTX UV Photoinitiator

  1. Cationic printing inks - Various cationic printing inks and overprint varnishes, fast curing, high printing precision

  2. Can coatings field - Can UV coatings, high solvent and corrosion resistance, suitable for food contact-related packaging

  3. Coil coatings field - UV-curable coil coatings, low shrinkage, strong adhesion, suitable for continuous production

  4. Pharmaceutical packaging inks - UV inks for pharmaceutical packaging, benzene-free and low-odor, meeting strict compliance requirements

  5. Cationic system sensitization - Sensitization of iodonium salts in cationic solids, improving cationic curing efficiency
