IGM Omnirad 4MBZ flakes is a high-efficiency benzophenone Type II free radical UV photoinitiator in the Omnirad series, designed for UV radiation curing systems. In the form of flake solid, it needs to be used synergistically with tertiary amine synergists. When exposed to UV light, it can efficiently initiate the free radical polymerization of acrylates and other unsaturated oligomers. Benzene-free, low-odor and highly compatible, it is suitable for various UV curing formulations
Benzophenone Type II initiation - Synergizes with tertiary amine synergists, high free radical initiation efficiency and stable polymerization reaction
Flake solid form - Flake structure easy to weigh and dissolve, convenient storage and transportation, accurate and controllable addition
Benzene-free low-odor environmental protection - Benzene-free formula, extremely low odor, meets high-end environmental compliance, suitable for sensitive scenarios
Multi-system compatibility - Compatible with various acrylate systems, suitable for solvent-based and water-based UV curing formulations, strong versatility
Wide adaptability - Suitable for colored and transparent systems, no impact on the appearance and performance of end products
Printing ink field - Offset, screen, flexo inks and overprint varnishes, fast curing, high printing precision
Wood coating field - Wood UV varnishes/colored paints, strong adhesion, scratch resistance, improving wood decoration durability
