IGM Omnirad BP flakes is a high-efficiency benzophenone Type II free radical UV photoinitiator in the Omnirad series, designed for UV radiation curing systems. As a widely used Type II initiator, it can efficiently decompose to generate free radicals when exposed to UV light, quickly initiating the polymerization of acrylates and other unsaturated oligomers. With flake form for easy processing and control, it has strong compatibility and outstanding cost performance
High-efficiency Type II initiation - Benzophenone core structure, high free radical initiation efficiency, fast curing speed, suitable for surface and through cure
Significant synergistic effect - When used with tertiary amine synergists, it can greatly improve initiation performance and curing effect
Multi-system adaptation - Compatible with clear, white, pigmented and water-based systems, extremely versatile, no formula adjustment needed
Easy flake control - White flake solid, easy to weigh, store and transport, accurate addition and convenient processing
High purity and stability - High purity, low volatility, stable performance during storage and processing, excellent batch consistency
Printing ink field - Offset, screen, flexo inks, fast curing, high printing precision, suitable for various substrates
Wood coating field - Wood UV varnishes/colored paints, strong adhesion, improving wood weather resistance and decorative texture
Plastic coating field - UV protective coatings for plastic surfaces, excellent scratch resistance and chemical resistance, good fit
Paper coating field - Paper UV curing coatings, high efficiency curing, enhancing paper surface wear resistance and gloss
UV adhesive field - Universal acrylate UV adhesives, high bonding strength, suitable for conventional bonding scenarios
