In the dynamic world of coatings and inks, achieving rapid curing, exceptional durability, and aesthetic appeal is paramount. Ultraviolet (UV) curing technology has revolutionized these industries by offering a fast, energy-efficient, and environmentally friendly alternative to traditional thermal curing methods. At the heart of many UV-curable formulations lies a critical component: the photoinitiator. NINGBO INNO PHARMCHEM CO.,LTD. is proud to highlight the significant contributions of Photoinitiator 1173, chemically known as 2-Hydroxy-2-methyl-1-phenylpropan-1-one (CAS: 7473-98-5), to the advancement of UV curing technologies.

Photoinitiator 1173 stands out as a highly efficient liquid photoinitiator. Its primary function is to initiate the photopolymerization process. This means that upon exposure to UV light, the molecule breaks down into reactive free radicals. These radicals then trigger the rapid polymerization of monomers and oligomers present in the formulation, transforming a liquid coating or ink into a solid, durable film. This rapid transformation is what makes UV curing so attractive in high-speed manufacturing environments.

One of the most valued attributes of Photoinitiator 1173 is its ability to create non-yellowing UV curable systems. Many photoinitiators, upon exposure to light or heat, can undergo degradation that results in unwanted yellowing of the cured film. This is particularly problematic for clear coats, white inks, and light-colored formulations where color integrity is crucial. Photoinitiator 1173 is specifically designed to minimize this effect, ensuring that the final product retains its original appearance and color stability over time. This characteristic makes it an indispensable component when formulating UV curable clear coatings for paper, plastics, and metals, where pristine finish is often required.

Furthermore, Photoinitiator 1173 exhibits a notable synergistic effect when used in conjunction with hindered amine light stabilizers (HALS), such as those offered by NINGBO INNO PHARMCHEM CO.,LTD. This combination is particularly effective in reducing the yellowing of urethane acrylate systems, especially when these materials are intended for outdoor applications and are directly exposed to sunlight. The HALS work by scavenging free radicals generated by UV exposure, thereby preventing photodegradation, while the photoinitiator ensures efficient curing. Together, they provide enhanced long-term performance and durability.

The formulation flexibility offered by Photoinitiator 1173 is another key advantage. As a liquid UV curing agent with excellent compatibility, it is exceptionally easy to incorporate into various UV-curable formulations. This ease of use makes it highly suitable for blends with other photoinitiators, allowing formulators to fine-tune the curing characteristics and performance profiles of their products. Whether developing fast-drying UV inks or robust protective coatings, the ability to create tailored blends is invaluable. The recommended dosage for optimal performance typically ranges from 1-4% by weight, providing a good balance of efficiency and cost-effectiveness.

In summary, Photoinitiator 1173 (2-Hydroxy-2-methyl-1-phenylpropan-1-one) is a cornerstone chemical for NINGBO INNO PHARMCHEM CO.,LTD. and the broader UV curing industry. Its high efficiency, non-yellowing properties, synergistic capabilities with light stabilizers, and ease of formulation make it an ideal choice for a wide array of applications, from high-quality coatings to vibrant inks. By understanding and utilizing the benefits of this advanced photoinitiator, manufacturers can achieve superior product performance and meet the ever-evolving demands of the market.
