Usage:
From UV-curable floor coatings, which are widely used in the construction industry, to the layer of strong and beautiful plastic coatings on plastic products, photoinitiator EHA plays an irreplaceable role. Take a well-known commercial building as an example. The floor is subject to heavy footfall and friction every day. However, the UV-curable floor coating with photoinitiator EHA added not only has greatly improved wear resistance, but also remains shiny and bright over the long term. This is thanks to the dense curing structure formed by the coating under UV irradiation.
In the communications sector, optical fiber coatings are essential for ensuring the stability of optical fibers and the quality of signal transmission. The use of photoinitiator EHA in optical fiber coatings is like putting on a tough layer of “armor” for optical fibers. According to relevant research data, optical fiber coatings with added photoinitiator EHA can extend the service life of optical fibers in harsh environments by about 30%, because photoinitiator EHA promotes the formation of special chemical bonds during the curing process of the coating, enhancing the coating’s ability to protect the optical fiber.
For the electronics industry, the use of photoinitiator EHA in light-curing solder-resistant inks and light-curing marking inks for circuit boards is of particular significance. We know that circuit boards in electronic products are like the human nervous system, and their stability directly affects the performance of the product. Soldering inks containing photoinitiator EHA can precisely protect the parts of the circuit board that do not need to be soldered after curing with UV light, preventing problems such as short circuits. In one large electronics manufacturer, for example, the defective product rate due to circuit board failures has been reduced by about 25% thanks to the use of this advanced photo-curing soldering ink. Meanwhile, photoinitiator EHA in photo-curable marking inks ensures clear and durable markings, facilitating subsequent production, testing and maintenance processes.
In addition, photoinitiator EHA also plays an important role in the manufacture of optical discs. The coating on the surface of the disc needs to have high hardness, high transparency and good wear resistance. Photoinitiator EHA makes the disc coating meet these stringent requirements after UV curing, ensuring the stability of the data stored on the disc and the accuracy of reading.
It is worth mentioning that with the continuous development of technology, we can assume that if the molecular structure of photoinitiator EHA is further optimized, can we develop new coatings and inks suitable for more special environments? For example, in the aerospace industry, in the face of extreme temperature, radiation and pressure conditions, this optimized photoinitiator may help develop high-performance protective coatings to provide better protection for aerospace equipment, which will undoubtedly be another major breakthrough in the field of materials science. At the same time, we are also constantly exploring new materials and research results to further tap the potential of photoinitiator EHA to provide strong support for the development of more fields.
