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
High-activity difunctional initiation - Difunctional α-hydroxy ketone structure, strong initiation activity, fast curing speed and high efficiency
Special adaptation for transparent systems - Targeted optimization for transparent systems, no yellowing after curing, maintaining high light transmittance and gloss
Low environmental load advantage - Low VOC emission, low migration and low extraction value, meeting strict environmental and food contact standards
Broad-spectrum system compatibility - Suitable for acrylate prepolymer systems, compatible with solvent-based UV formulations, strong versatility
Easy processing and addition - Easy to disperse and weigh, can be added directly, convenient operation, improving production efficiency
Transparent UV varnishes - Transparent varnishes for wood, glass and plastic, high light transmittance, excellent decorativeness and protection
High-end UV coatings - High-end transparent UV coatings for plastic and metal, uniform curing, improving film wear resistance and weather resistance
Transparent UV inks - Screen and offset transparent UV inks, suitable for paper and plastic substrates, clear printing and stable color
Food packaging UV adhesives - Low migration and low extraction value, suitable for food packaging-related UV adhesives, safe and compliant
Precision electronic coatings - Transparent UV protective coatings for electronic components, no impact on component performance, excellent protection effect
