In terms of chemical structure and properties, photoinitiator 1173 is highly efficient, and most notably, it does not cause yellowing. This property is of great significance for unsaturated polyester systems and UV curing systems composed of multifunctional monomers. In these complex chemical systems, photoinitiator 1173 acts like an elegant conductor, methodically directing the curing reaction. It not only has the advantage of being low in odor, avoiding the unpleasant pungent smell during use, but also performs perfectly in terms of color stability. This color stability is like a loyal guardian protecting the kingdom of color, allowing the cured product to maintain its original color for a long time without the annoying yellowing problem. It is also worth mentioning that it has excellent compatibility and can be easily compounded with other photoinitiators, like puzzle pieces that work together to achieve a greater effect.

In the vast arena of practical applications, photoinitiator 1173 has shown itself to be extremely versatile. Take acrylic photo-curing varnish systems as an example. They can be used on everything from delicate wooden products and sturdy metal equipment to common paper and various types of plastic. If we look back at the development of the furniture manufacturing industry over the years, in the early days, before the advent of this highly effective photoinitiator, it often took a long time to cure the lacquer on wooden surfaces, and the finish was prone to discoloration and other problems. The advent of photoinitiator 1173 was like an injection of a strong heart stimulant into the industry, greatly improving production efficiency and product quality.

In modern industry, UV plastic coatings, UV wood coatings, UV paper inks and other fields are inseparable from the presence of photoinitiator 1173. It is like a hero behind the scenes in these fields, quietly driving the development of the industry. Market research data shows that products using photoinitiator 1173 have significantly improved in terms of quality stability and market acceptance. This is not only due to its excellent performance, but also because it adapts to the specific needs of the colorless system.

In addition, it complements 907, and in particular, it has a synergistic effect when used with TPO and 819 in UV-curable coatings and inks, transparent wood coatings, plastics and metals, and overprint varnishes. We might as well assume that without the presence of photoinitiator 1173, these complex industrial application scenarios may be in trouble. For example, in the printing of plastic films, if the color is unstable or the curing is incomplete, it will lead to a significant increase in the product’s rejection rate, which will cause huge economic losses to the company. The application of photoinitiator 1173 is like putting on a layer of sturdy armor for these industries, ensuring the smooth progress of production and high product quality.
From a deeper chemical perspective, the molecular structure of photoinitiator 1173 determines that it can efficiently generate free radicals under UV light irradiation, thereby initiating a polymerization reaction. This precise chemical reaction mechanism is the fundamental reason why it stands out among many photoinitiators. Moreover, its adsorption and reactivity on different material surfaces have also undergone extensive experimental research and optimization, which provides a solid theoretical basis for its wide application.
