The printing industry's reliance on UV-curable inks has grown exponentially, driven by their fast drying times, vibrant colors, and environmental benefits. Central to this technology is the photoinitiator, and Photoinitiator 1173 (2-Hydroxy-2-methylpropiophenone, CAS 7473-98-5) stands out as a highly effective option for UV inks.

As a leading supplier of specialty chemicals from China, we provide Photoinitiator 1173, a critical ingredient that enables rapid curing of UV inks upon exposure to ultraviolet light. This type of photoinitiator, specifically a Type I free radical initiator, works by directly generating free radicals when irradiated. These radicals then initiate the chain polymerization of acrylate monomers and oligomers present in the ink formulation.

The advantages of using Photoinitiator 1173 in UV inks are significant. Its high efficiency translates to faster printing speeds and improved throughput, which is a major advantage in high-volume printing operations. Furthermore, its excellent solubility ensures uniform dispersion within the ink, leading to consistent curing across the printed substrate. This consistent curing is vital for achieving sharp print quality, good adhesion, and desired tactile properties.

From a formulation perspective, Photoinitiator 1173 is highly compatible with a wide range of monomers and other additives commonly found in UV inks. This allows printers and ink manufacturers flexibility in developing custom formulations tailored to specific printing processes, such as screen printing, flexographic printing, and lithographic printing. The resulting inks exhibit good durability and resistance, making them suitable for various applications, including packaging, labels, and commercial printing.

For businesses seeking a reliable source for Photoinitiator 1173, partnering with a reputable Chinese manufacturer offers distinct advantages. We provide this essential chemical with a guaranteed purity of over 99%, ensuring that your ink formulations perform as expected. By sourcing directly from us, you can benefit from competitive price points and a stable supply chain, essential for managing production costs and ensuring uninterrupted operations. We encourage you to inquire about our bulk pricing and how to buy this product for your printing needs.

In summary, Photoinitiator 1173 is a highly effective and versatile photoinitiator for UV ink applications. Its ability to initiate rapid curing, coupled with its low yellowing and excellent compatibility, makes it a preferred choice. As your trusted supplier, we are committed to delivering high-quality 2-Hydroxy-2-methylpropiophenone to support the innovation and efficiency of the printing industry.
