UV absorber UV-327: “Invisible Guardian” in environmentally friendly coatings
In the world of paint, UV absorber UV-327 can be regarded as a low-key but indispensable hero behind the scenes. It is like an unknown bodyguard, resisting the “ultraviolet attack” from the sun for various paints and materials. This chemical can not only effectively absorb harmful ultraviolet radiation, but also significantly extend the service life of the paint, making our living space safer, more beautiful and lasting.
What is UV absorber UV-327?
UV absorber UV-327 is a highly efficient light stabilizer with a chemical name of 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. Its molecular structure is unique and can convert high-energy ultraviolet rays into low-energy thermal energy to release them, thereby avoiding the destruction of ultraviolet rays on the coating or substrate. Simply put, it is like an invisible umbrella that blocks us from invisible but extremely destructive ultraviolet rays.
Main functions of UV-327
- Prevent aging: UV rays are one of the main culprits that cause paint to discolor, powder or even peel. UV-327 can effectively delay the occurrence of these aging phenomena by absorbing ultraviolet rays.
- Improving weather resistance: Whether it is outdoor buildings or automotive surfaces, the UV-327 can enhance the coating’s UV resistance, allowing it to remain bright and complete in the sun for longer.
- Protecting substrate: In addition to protecting the coating itself, UV-327 can indirectly protect the coated substrate from ultraviolet rays, such as plastic products, wood, etc.
Application Fields
UV-327 is widely used in various coatings, plastics, rubbers and other materials that require light stability. Especially in the field of environmentally friendly coatings, its use is becoming increasingly popular. As people’s awareness of environmental protection increases, more and more companies are choosing to use green products that do not contain heavy metals or other harmful ingredients, and UV-327 is such an ideal additive.
Detailed explanation of product parameters of UV absorber UV-327
In order to better understand the performance characteristics of UV-327, we can fully understand this “Invisible Guardian” through the following key parameters.

Innovative application of UV-327 in environmentally friendly coatings
As the global emphasis on sustainable development continues to increase, environmentally friendly coatings have gradually replaced traditional coatings and become the mainstream market. In this process, UV-327, as a high-performance ultraviolet absorber, played an irreplaceable role.
Why choose UV-327?
Compared with other UV absorbers, UV-327 has the following significant advantages:
- Environmentally friendly: UV-327 does not contain toxic heavy metals, nor does it produce harmful by-products, and it fully complies with modern environmental protection standards.
- Efficient absorption: It can absorb ultraviolet rays within a wide wavelength range (280nm-380nm), providing all-round protection.
- Strong compatibility: UV-327 is well compatible with most coating systems and will not affect the appearance or performance of the final product.
- Economy and affordable: Despite its excellent performance, its production cost is relatively low and is suitable for large-scale industrial applications.
Examples of innovative application scenarios
1. Building exterior wall coating
Incorporating UV-327 into building exterior wall coatings can significantly improve the coating’s weather resistance and UV resistance. This means that the exterior walls of buildings can not only keep their colors bright for a long time, but also reduce cracks and falls caused by ultraviolet rays. In addition, since UV-327 itself has environmentally friendly properties, this type of coating is more in line with the current development trend of green buildings.
2. Car paint protection
For the automotive industry, maintenance of vehicle paint is crucial. UV-327 is widely used in automotive varnish formulas, helping car owners solve problems such as fading and cracking of paint surfaces due to long-term exposure to the sun. At the same time, it can also work in concert with other functional additives to further optimize the overall performance of the paint surface.
3. Interior Decoration Paints
While indoor environments are usually not directly affected by strong UV rays, in certain special cases (such as near windows or balcony), UV rays can still cause damage to the walls. By adding UV-327, interior decorative paint can not only extend its service life, but also create a healthier and more comfortable living space for residents.
The current situation and development prospects of domestic and foreign research
In recent years, many important progress has been made in the research on the ultraviolet absorber UV-327. The following are some domestic and foreign literature achievements worth paying attention to:
Domestic research trends
According to a research report by a research group of a research group of the Chinese Academy of Sciences, the application effect of UV-327 in nanocomposite coatings is particularly outstanding. The researchers found that when UV-327 is combined with nanotitanium dioxide, the comprehensive performance of the paint can be significantly improved, including mechanical strength, wear resistance and antibacterial properties. This research results provide new ideas for the future development of multifunctional environmentally friendly coatings.
International Frontier Exploration
In an experiment at the MIT Institute of Technology, scientists tried to introduce UV-327 into a self-healing coating system. The results show that the improved paint not only has excellent UV resistance, but also can automatically return to its original state after minor damage. Once this technology matures and is put into practical application, it will completely change the pattern of the traditional coatings industry.
Development prospects
Looking forward, with the continuous advancement of new materials science and technology, the application potential of UV-327 will be further explored. For example, it is expected to play a more important role in the fields of smart paints, biomedical paints, etc. At the same time, with the continuous increase in environmental protection policies by governments in various countries, UV-327, as a truly green chemical, will surely usher in a broader range.Broad development space.
Conclusion
In short, UV absorber UV-327 is not only a shining pearl in the field of environmentally friendly coatings, but also an important force in promoting the entire industry to move towards sustainable direction. As the old saying goes, “Details determine success or failure.” It is precisely because of the seemingly inconspicuous but crucial components like the UV-327 that we can enjoy a better and more lasting living environment. So, next time you see a wall that has gone through storms but is still as bright as a new one, please remember to thank this “invisible guardian” who has made silent efforts!
