기능 & 애플리케이션:

In the early days, traditional curing methods were unable to cope with the complex material and process requirements. The emergence of UV light curing technology was like a ray of light in the darkness. The birth of photoinitiator 819 has given this technology a powerful impetus. Its unique properties have enabled UV light curing to break through many limitations and advance towards a wider range of applications.

The unique feature of photoinitiator 819 is its extraordinary “control” of light. It is like a master at precisely capturing light energy, with a strong ability to absorb long-wave ultraviolet light (such as 365 nm and 405 nm) and some visible light. This ability is not simply a physical phenomenon, but has a profound chemical rationale behind it. This special ability to absorb light makes photoinitiator 819 work wonders in thicker coatings or deep areas, achieving excellent curing results.

In practical applications in the field of UV light curing, photoinitiator 819 has performed amazingly.

Let’s look at the field of light curing of thick film coatings. While traditional photoinitiators often “run out of steam” when faced with thick coatings and thick film curing applications, 819 comes forward like a superhero. Its amazingly high absorption efficiency and excellent deep penetration are its magic weapons. Take thick film coatings on wood, plastic and metal surfaces, for example. Achieving even curing on these materials is a real challenge. However, 819 can handle it with ease. It penetrates deep into the coating, promoting simultaneous curing of the inner layers and the surface, and achieving even curing results. This is like building a tall building. It not only ensures that the facade is strong and beautiful, but also that the internal structure is equally solid and stable, ensuring the quality of the entire building.

Photocure 819 also has a unique advantage when it comes to opaque or colored coatings. Here, the absorption and utilization of visible light is key. 819’s absorption capacity in the visible light range is like opening a new door. Take colored inks and opaque coatings as examples. These materials often interfere with the effect of photoinitiators, but 819 can still initiate the polymerization reaction in such a complex environment and achieve good curing results. It is like a ship navigating through a fog, using special navigation equipment (the visible light absorption ability of 819) to find the right direction and successfully reach its destination (curing).

Photoinitiator 819 also shines in the application of UV adhesives. UV-curing adhesives play an important role in modern industry and life in general for bonding glass, ceramics, plastics and metals. 819 is the glue’s “smart brain”, enabling it to cure quickly under UV light and with amazing yellowing resistance. This is crucial for bonding applications that require long-term aesthetics and transparency. For example, in the assembly of high-end electronic products, the bonding of glass screens to plastic bezels or metal parts using UV adhesives containing 819 not only ensures a strong bond, but also maintains transparency after long-term use, without affecting the appearance and performance of the product due to yellowing. It is as if the bond has been given eternal youth.

Photoinitiator 819 also demonstrates its unparalleled value in the field of 3D printing photoresin. In this field full of innovation and challenges, high-precision printing results are the goal. 819’s initiation efficiency and deep curing ability are like the “secret weapon” of 3D printing. Especially when dealing with printing tasks that are thicker or have complex structures, it can quickly take effect and achieve rapid curing. This is like a skilled sculptor, when shaping complex works of art, 819 can help resin materials to quickly take shape, and ensure that every detail is accurate, promoting the wide application of 3D printing technology in industrial design, medical model manufacturing and other fields.

Photoinitiator 819 also performs excellently in LED curing applications. As technology develops, low-energy LED curing equipment is gradually becoming the mainstream. 819’s characteristic of being able to effectively absorb long-wave UV and some visible light makes it a perfect match for LED light sources such as 365nm or 405nm LEDs. This good compatibility is like two tacit partners, working together to contribute to a low-energy, high-efficiency curing system. Today, when environmental protection and energy conservation are becoming increasingly important, the advantages of 819 in LED curing applications are particularly prominent, providing strong support for green manufacturing.

In addition, photoinitiator 819 has a clever application strategy, which is to be used in combination with other initiators (such as 184, TPO, etc.). It’s like forming a super team, where each member has its own specialty and they collaborate and complement each other. By using this mixture, the curing speed and material properties can be optimized, thus taking photocuring to a new level. Behind this is the complex principle of chemical synergy. The ratio and interaction between them is like a mysterious formula, which brings more possibilities to UV light curing technology.
