CHLUMINIT® OXE-02 Usage:

From architectural decoration to electronic equipment manufacturing, from everyday printed matter to the production of high-end precision instruments, materials such as UV coatings, UV inks and UV adhesives all play an indispensable role. The application of the photoinitiator OXE-02 in these materials is extensive and significant. Take UV coatings, for example. In the coating of building facades, these coatings not only dry quickly, but also have excellent weather resistance. The photoinitiator OXE-02 plays a key role in initiating the polymerization reaction, which causes the coating to cure quickly and form a strong and beautiful coating. Similarly, UV inks used in the manufacture of electronic devices require high-precision printing results. Photoinitiator OXE-02 ensures that the ink cures precisely under UV light, ensuring the clarity and durability of the printed pattern.

It is also worth mentioning that it also performs excellently in the field of UV adhesives. For example, in the assembly of automotive parts, a fast-curing and high-strength adhesive is required, and UV adhesives are the first choice. The photoinitiator OXE-02 is the core factor that allows this adhesive to perform its powerful function. In addition, it also plays an irreplaceable role in preservatives and fluxes. In the corrosion protection of metal products that are exposed to harsh environments for long periods of time, corrosion inhibitors containing photoinitiator OXE-02 can form a dense protective film to effectively prevent the metal from being eroded by the external environment.

In actual use, there are strict requirements for the amount of photoinitiator OXE-02 used. According to a large amount of experimental data and industrial practice, the recommended dosage is 0.5–5% (w/w). This dosage range is not set arbitrarily, but is the result of repeated testing. When the dosage is lower than 0.5%, the polymerization reaction may not be initiated effectively, resulting in substandard product performance. For example, UV coatings may not dry completely, resulting in poor adhesion. When the dosage exceeds 5%, not only will the cost increase, but some negative effects may also occur. For example, excessive polymerization may make the product brittle, affecting its flexibility and durability.

this dosage range is also affected by other factors in different application scenarios, such as the intensity of UV light, irradiation time, ambient temperature, etc. Assuming that UV coating is applied in a high-temperature environment, due to the effect of temperature on the reaction rate, the dosage of photoinitiator OXE-02 may need to be slightly adjusted by reducing the dosage appropriately to avoid quality problems caused by excessive reaction. On the contrary, in a low-temperature environment or when the UV light intensity is weak, the dosage may need to be slightly increased to ensure the reaction proceeds normally. These are all complex factors that need to be considered in the actual production process, which further highlights the importance of accurately controlling the dosage of photoinitiator OXE-02.
