IGM Omnirad 410 is a high-efficiency fine-grinded benzophenone Type II free radical UV photoinitiator in the Omnirad series, designed for UV radiation curing systems. Its core component is 4-Phenylbenzophenone. It can efficiently decompose to generate free radicals when exposed to UV light, quickly initiating the polymerization of acrylates and other unsaturated oligomers. The fine-grinding process improves dispersibility, with strong compatibility and stable performance,
High-efficiency Type II initiation - Benzophenone structure, high free radical initiation efficiency, excellent surface and deep curing effect
Fine-grinding advantage - Uniform powder particle size, excellent dispersibility, easy to integrate into various formulations, avoiding agglomeration
Broad-spectrum compatibility - Suitable for acrylate systems, compatible with water-based and solvent-based formulations, strong versatility
Multi-system adaptability - Suitable for transparent, white and pigmented systems, uniform curing, no impact on the color of end products
Easy solid control - White to off-white powder, easy to weigh, store and transport, accurate addition and convenient processing
UV coating field - Wood, metal, plastic UV coatings, fast curing, improving coating wear resistance and adhesion
UV ink field - Offset, screen, flexo inks, suitable for various substrates, high printing precision and stable color
Water-based system field - Water-based UV coatings, water-based UV adhesives, good dispersibility and excellent curing performance
Wood coating field - Wood UV varnishes/colored paints, good decorativeness, not easy to lose light and discolor after long-term use
Industrial coating field - Industrial metal and plastic protective coatings, suitable for radiation curing process, improving protective performance
