Genel Bilgiler:

379 belongs to α-aminoketone derivatives, which has good thermal stability, long storage period, good solubility, light color, good anti-yellowing performance, fast light curing speed, and good deep curing performance.

In the photopolymerization imaging system, it is a substance that is directly sensitive to light and promotes the polymerization of monomers into polymer compounds. α-Aminoketone derivatives are an important class of photoinitiators, and 379 is one of them. It has been widely used in the field of UV curing, and is widely used in photocurable coatings, inks, photoresist Etching and other fields.

Kullanım:

The high efficiency of photoinitiator 379 is like a “lightning attack” in a chemical reaction. When exposed to ultraviolet light, it can quickly and massively produce free radicals, a process that is like an efficient chain reaction. From a chemical kinetic point of view, this ability to efficiently produce free radicals allows the polymerization reaction to proceed quickly and completely, greatly reducing the curing time and improving production efficiency. This is undoubtedly a key factor in reducing costs and increasing production for mass production.

Its broad-spectrum response is like a “detector” with a wide field of view. The broad absorption spectrum in the ultraviolet region means that it can “cooperate” with various ultraviolet light sources. Whether it is a traditional mercury lamp ultraviolet light source or a new LED ultraviolet light source, photoinitiator 379 can adapt. This provides great flexibility in the selection of equipment for the production process. Companies can choose the most suitable ultraviolet light source according to their own needs and cost considerations, without worrying about the compatibility of the photoinitiator.

Good thermal stability is another advantage of photoinitiator 379. In high-temperature processing environments, it is like a tough warrior, not losing its activity due to high temperatures. In some processes that require high-temperature treatment, such as high-temperature baking after UV coating on certain special metal surfaces to enhance adhesion, photoinitiator 379 can still function stably to ensure the curing quality of the coating.

Low migration characteristics act as a stable “anchor” to ensure the long-term durability of cured products. In many products with stringent quality requirements, such as UV coatings for food packaging materials, if the photoinitiator migrates into the food, it may pose a safety risk. However, the low migration characteristics of photoinitiator 379 eliminate this concern, making the cured product stable and safe over time.

In addition, its low odor makes photoinitiator 379 stand out in scenarios where environmental and human health requirements are high. In the field of interior paints, people are very sensitive to odors. For example, in hospitals, schools, homes and other places, using low-odor formulations containing photoinitiator 379 not only allows for quick renovation and maintenance, but also provides a comfortable and healthy environment. According to a study on indoor air quality, the volatile organic compound (VOC) content in indoor spaces with low-odor paints is significantly lower than that in spaces with traditional paints, which further proves the important role of photoinitiator 379 in improving the indoor environment.

Compared to 369, 379 differentiates especially due to its substantially improved solubility which allows its use for applications in which 369 is at the solubility limit or couldn’t be used at all due to the limited solubility.
