The printing industry has increasingly embraced UV-curable inks due to their rapid drying capabilities, excellent adhesion, and reduced environmental impact compared to solvent-based inks. Central to the performance of these inks is the photoinitiator, and NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the significant role of Methyl 2-benzoylbenzoate (MBB) in achieving optimal results.

MBB, with CAS number 606-28-0, is a versatile Type II photoinitiator that is instrumental in the UV polymerization of inks used in a variety of printing technologies, including offset, flexographic, and screen printing. Its ability to initiate rapid free-radical polymerization, especially when paired with amine synergists, ensures quick and efficient curing of the ink film upon UV light exposure.

A key advantage of MBB in ink formulations is its low odor profile. This characteristic is highly valued across the printing sector, particularly for applications such as graphic arts, decorative coatings, and, as previously mentioned, food packaging. By minimizing odor, MBB contributes to a better working environment for print operators and ensures that the printed materials do not carry unwanted smells, which is crucial for consumer acceptance.

The chemical’s low volatility is another significant benefit, leading to reduced emissions and a safer atmosphere within printing facilities. Furthermore, MBB's absorption spectrum allows for efficient curing, even in thicker ink layers or when pigmented with titanium dioxide, which can sometimes hinder UV penetration.

NINGBO INNO PHARMCHEM CO.,LTD. provides MBB that meets stringent purity requirements for use in demanding UV-curable ink applications. The recommended usage levels, typically 0.5-5% w/w of MBB along with 2-5% w/w of an amine synergist, can be adjusted to tailor the curing speed and performance characteristics of the ink for specific printing processes and substrate types.

The versatility of MBB extends to its role in producing high-quality prints that are resistant to abrasion, chemicals, and fading. This makes it an indispensable component for printers seeking to deliver durable, visually appealing, and environmentally responsible printed products. By choosing NINGBO INNO PHARMCHEM CO.,LTD.'s Methyl 2-benzoylbenzoate, ink manufacturers can enhance their product offerings with superior curing technology, ensuring fast production cycles and exceptional print quality.
