IGM Omnirad OMBB is a low-odor benzoylbenzoate Type II free radical UV photoinitiator in the Omnirad series, designed for UV radiation curing systems. Its core component is Methyl o-benzoylbenzoate. When used with tertiary amine synergists, it can efficiently initiate the free radical polymerization of acrylates and other unsaturated oligomers.t,
Low-odor and environmental protection - Extremely low odor of itself and photolysis products, suitable for indoor, closed and other sensitive construction scenarios
High-efficiency Type II initiation - Synergizes with tertiary amine synergists, high free radical initiation efficiency and fast curing speed
Multi-system compatibility - Suitable for solvent-based UV formulations, compatible with various acrylate oligomers, strong versatility
Easy solid control - White to off-white crystalline solid, easy to weigh, store and transport, accurate addition
High purity and stability - Purity ≥99.0%, moderate melting point, excellent batch consistency, stable performance during long-term storage
UV ink field - Offset, screen, flexo inks, fast curing, suitable for various substrates, no odor interference
Varnish field - Paper and plastic overprint varnishes, improving surface gloss and wear resistance, uniform curing
Wood coating field - Wood UV varnishes/colored paints, low-odor and environmental protection, with both decorativeness and durability
Plastic coating field - UV protective coatings for plastic surfaces, good fit, excellent scratch resistance and chemical resistance
Universal curing field - Various UV free radical curing systems, suitable for conventional low-odor curing needs
