IGM Esacure ES 198 Photoinitiator

IGM ES 198 is a high-efficiency amine synergist in the IGM Esacure series, specially designed for various UV radiation curing systems. Used in combination with Type II photoinitiators, it achieves high-speed curing in both transparent and pigmented systems. Under UV light, it effectively promotes free radical generation, accelerates photopolymerization of unsaturated prepolymers such as acrylates with mono and multifunctional monomers

Features Of IGM Esacure ES 198 Photoinitiator

  1. Significant synergistic effect - Compounded with Type II photoinitiators, greatly improving curing speed and enhancing deep curing effect

  2. Dual-system adaptability - Suitable for both transparent and pigmented UV systems, wide application range, no impact on system color

  3. Low odor and low yellowing - Extremely low odor during curing, no obvious yellowing after curing, maintaining product appearance texture

  4. Low migration and low extraction - Special molecular structure, meeting low migration and low extraction value requirements, suitable for strict scenarios

  5. Easy compounding and processing - Good compatibility with various UV formulations, easy to disperse and weigh, convenient operation, improving production efficiency

Typical Applications Of IGM Esacure ES 198 Photoinitiator

  1. Transparent UV varnishes - Transparent varnishes for wood, glass and plastic, low yellowing, maintaining high light transmittance and gloss

  2. Pigmented UV coatings - Wood and plastic pigmented UV coatings, fast curing, full color and good wear resistance

  3. UV ink field - Screen and offset UV inks, suitable for paper and plastic substrates, clear printing and low odor

  4. Food packaging UV systems - Low migration and low extraction, suitable for food packaging-related UV curing products, safe and compliant

  5. High-end UV adhesives - Transparent and pigmented UV adhesives, high bonding strength, no yellowing, suitable for precision bonding scenarios
