BASF IRGACURE 2100 Photoinitiator

BASF IRGACURE 2100 is a liquid UV photoinitiator in the IRGACURE series, clear yellow viscous liquid, active component IRG 819, easier to handle/deeper curing than LUCIRIN TPO, suitable for white/low-yellowing formulations, compoundable with α-hydroxy ketones, ideal for inks/adhesives/coatings.

Features Of BASF IRGACURE 2100 Photoinitiator

  1. Efficient UV initiation - Rapid free-radical generation under UV, suitable for thick films, improving through-cure efficiency

  2. Excellent processability - Liquid form easy to mix, more convenient than LUCIRIN TPO, reducing processing costs

  3. Low yellowing/color stability - Suitable for white formulations, minimal yellowing after curing, reducing pigment aggregation

  4. Compounding synergy - Compoundable with α-hydroxy ketones, balancing surface/through-cure, suitable for multi-system formulations

  5. Broad compatibility - Compatible with solvents/acrylates, suitable for varnishes/pigmented coating

Typical Applications Of BASF IRGACURE 2100 Photoinitiator

  1. Printing inks - Screen/flexo inks, suitable for white/colored systems, improving curing speed/color stability

  2. Adhesives - UV-curable adhesives, suitable for multi-substrate bonding, improving bond strength/chemical resistance

  3. Multi-substrate coatings - Varnishes/pigmented coatings for wood/paper/metal/plastic/fibers, ensuring coating performance

  4. White paint systems - White UV coatings, ensuring low yellowing/low pigment aggregation, improving coating appearance

  5. Thick-film curing - Thick-film UV coatings, better through-cure than LUCIRIN TPO, ensuring uniform curing
