IGM ES ONE Photoinitiator

IGM ES ONE is a high-activity difunctional α-hydroxy ketone free radical UV photoinitiator in the IGM Esacure series, specially designed for various UV radiation curing systems. Its unique difunctional molecular structure provides high-efficiency initiation performance. It can quickly decompose to generate free radicals under UV light, efficiently initiating photopolymerization of unsaturated prepolymers such as acrylates with mono and multifunctional monomers

Features Of IGM ES ONE Photoinitiator

  1. High-activity difunctional initiation - Difunctional α-hydroxy ketone structure, strong initiation activity, fast curing speed and high efficiency

  2. Special adaptation for transparent systems - Targeted optimization for transparent systems, no yellowing after curing, maintaining high light transmittance and gloss

  3. Low environmental load advantage - Low VOC emission, low migration and low extraction value, meeting strict environmental and food contact standards

  4. Broad-spectrum system compatibility - Suitable for acrylate prepolymer systems, compatible with solvent-based UV formulations, strong versatility

  5. Easy processing and addition - Easy to disperse and weigh, can be added directly, convenient operation, improving production efficiency

Typical Applications Of IGM ES ONE Photoinitiator

  1. Transparent UV varnishes - Transparent varnishes for wood, glass and plastic, high light transmittance, excellent decorativeness and protection

  2. High-end UV coatings - High-end transparent UV coatings for plastic and metal, uniform curing, improving film wear resistance and weather resistance

  3. Transparent UV inks - Screen and offset transparent UV inks, suitable for paper and plastic substrates, clear printing and stable color

  4. Food packaging UV adhesives - Low migration and low extraction value, suitable for food packaging-related UV adhesives, safe and compliant

  5. Precision electronic coatings - Transparent UV protective coatings for electronic components, no impact on component performance, excellent protection effect
