IGM Esacure ONE Photoinitiator

IGM Esacure ONE is a high-efficiency bifunctional solid UV photoinitiator in the Esacure® series, formerly BASF, off-white powder, a bifunctional α-hydroxy ketone PI. It absorbs UV energy to generate free radicals, initiates polymerization of unsaturated oligomers and acrylates, FDA-approved (FCN772), suitable for low-VOC, low-migration systems like food packaging, UV adhesives, coatings and inks.

Features Of IGM Esacure ONE Photoinitiator

  1. Bifunctional efficient initiation - Dual active sites, rapidly generates free radicals, curing efficiency exceeds ordinary monofunctional PIs

  2. Low migration and extraction - Special molecular structure, suitable for low-VOC systems, meeting strict environmental requirements like food packaging

  3. Excellent compliance - FDA-approved (FCN772), usable in food packaging-related UV curing scenarios

  4. Broad system compatibility - Soluble in most organic solvents and monomers, suitable for UV coatings, inks, adhesives and other systems

  5. Excellent curing quality - Complete curing without residue, improves coating adhesion and weatherability, non-yellowing

Typical Applications Of IGM Esacure ONE Photoinitiator

  1. UV food packaging inks - Low migration and residue, suitable for food packaging printing, meeting environmental compliance requirements

  2. Transparent UV coatings - Clear coatings for wood/plastic/metal, non-yellowing after curing, improving surface texture

  3. UV adhesives - Various fast-curing UV adhesives, shortening curing cycle, enhancing bond strength and stability

  4. Powder coatings field - UV powder coatings, suitable for multi-substrates, improving coating density and durability

  5. High-end printing inks - Offset/screen inks, ensuring printing precision, meeting low-migration environmental standards
