UV absorber UV-326: Wearing “sun protection clothes” for building glass

On sunny days, the sunshine pouring through the windows always makes people feel warm and comfortable. However, behind this beauty is a problem that cannot be ignored – the harm of ultraviolet rays. Long-term exposure to ultraviolet light will not only cause indoor items to fade and age, but may also pose a potential threat to human health. How to effectively resist the harm of ultraviolet rays has become an important issue that needs to be solved urgently in modern architecture.

UV absorber UV-326, as an efficient functional material, is gradually becoming a star product that improves the sun protection performance of building glass. It is like an invisible “sun protection clothing”, which can block harmful ultraviolet rays and allow visible light to pass smoothly, thereby maintaining a good lighting effect while protecting the indoor environment. This article will explore the characteristics of UV absorber UV-326 and its application in architectural glass from multiple angles, and let you understand the mystery behind this technology.

What is UV absorber UV-326?

Definition and Function

UV absorber UV-326 is a chemical substance specially used to absorb ultraviolet rays and belongs to a benzotriazole compound. Its main function is to capture ultraviolet energy through specific groups in the molecular structure and convert it into heat and release it, thereby avoiding direct damage to the material or the human body by ultraviolet light. Simply put, UV-326 is like an accurate “filter umbrella”, which can filter out harmful ultraviolet bands without affecting the transmission of other beneficial light.

Chemical structure and working principle

The chemical name of UV-326 is 2-(2′-hydroxy-5′-methylphenyl)benzotriazole, and its molecular formula is C15H13N3O. This compound has a highly stable chemical structure and can maintain excellent UV absorption capacity for a long time. Specifically, the working principle of UV-326 is as follows:

  1. Selective Absorption: UV-326 can preferentially absorb ultraviolet rays (including UVA and UVB) in wavelength range between 290nm and 400nm, which is a band with a great impact on human health and material aging.
  2. Energy Conversion: When ultraviolet rays are absorbed, UV-326 will convert these high-energy photons into low-energy thermal energy, and then disperse them into the environment in the form of heat, thereby achieving harmless treatment.
  3. Stability Maintenance: Even after multiple absorption and release cycles, UV-326 can still maintain high activity and is not easy to decompose or fail.

This unique mechanism makes UV-326 an ideal UVWire protective materials are widely used in plastics, coatings, textiles and architectural glass.

Detailed explanation of the product parameters of UV-326

To better understand the technical characteristics of UV-326, we can display its key parameters through the following table:

parameter name Unit Value Range Remarks
Appearance – White crystalline powder Easy to disperse, suitable for a variety of processing techniques
Melting point °C 148-152 High temperature stable, suitable for thermoplastic material processing
Solution g/100ml Insoluble in water, soluble in organic solvents Common solvents include methanol, etc.
Absorption wavelength nm 290-400 Cover the UVA and UVB bands
Large absorption efficiency % >98 Excellent performance in specified wavelength range
Photochemical stability – >1000 hours Verified by accelerated aging test
Toxicity LD50 (mg/kg) >5000 Complied with EU REACH regulations

It can be seen from the table that UV-326 not only has excellent ultraviolet absorption capacity, but also has good physical and chemical properties, which provides a solid guarantee for its performance in practical applications.

The application advantages of UV-326 in architectural glass

Introducing UV-326 into the field of architectural glass can not only significantly improve the sun protection performance of glass, but also bring a series of added value. Here are some of the main application advantages:

Improving sun protection effect

Although ordinary transparent glass in a building allows most visible light to enter the room, it also allows a large amount of ultraviolet rays to penetrate. researchIt has been shown that unprotected glass windows may cause more than 70% of ultraviolet rays to enter the room, which causes irreversible damage to indoor furniture, floors and other decorations. The special coated glass with UV-326 can reduce this proportion to less than 5%, greatly extending the service life of indoor items.

Improving living comfort

In addition to protecting property, reducing ultraviolet radiation can also improve people’s living experience. For example, long-term exposure to ultraviolet light can easily cause skin problems and even increase the risk of cancer. Therefore, installing sunscreen glass containing UV-326 ingredients in home or office is undoubtedly a strong care for the health of the family.

Energy saving and environmental protection benefits

It is worth noting that using UV-326 treated glass also helps reduce air conditioning energy consumption. This is because the ultraviolet rays themselves carry higher energy, and when they are blocked outside, the temperature fluctuations in the room will be more stable, thus reducing the workload of the refrigeration equipment. It is estimated that the use of such high-performance glass can reduce the power consumption of air conditioners in summer by about 15%-20%.

The current situation and development trends of domestic and foreign research

In recent years, as people pay more attention to environmental protection and sustainable development, the research and development of the ultraviolet absorber UV-326 has also made significant progress. Here are some directions worth paying attention to:

Exploration of new composite materials

Scientists are trying to combine UV-326 with other functional additives to develop more efficient composite materials. For example, some experiments have shown that modifying a thin UV-326 coating on the surface of nanotitanium dioxide (TiO2) can further enhance its photocatalytic activity while giving the material stronger UV shielding ability. This innovative approach is expected to be applied in high-end architectural exterior wall design in the future.

Research and development of intelligent responsive glass

Another exciting research area is the development of smart responsive glass. This type of glass can automatically adjust the light transmittance according to the external light intensity, thereby achieving dynamic sun protection function. At present, a team has proposed a conceptual solution based on UV-326 modified polymer film. This solution uses an external light source to trigger internal chemical reactions to achieve the purpose of real-time regulation.

Promotion of environmentally friendly products

With the rise of global green building trends, more and more companies are beginning to pay attention to the environmental performance of UV-326 production process. By optimizing the synthesis route and reducing by-product emissions, the new generation of environmentally friendly ultraviolet absorbers are gradually entering the market. These products not only meet strict international standards requirements, but also make positive contributions to promoting the sustainable development of the entire industry.

Conclusion

In short, UV absorber UV-326 is gradually becoming a building with its excellent performance and broad application prospects.An indispensable and important component of the glass field. Whether for individual users who pursue high-quality life or professionals who are committed to building low-carbon and environmentally friendly buildings, UV-326 provides a practical technical solution. Let us look forward to this technology continuing to break through itself in the future and creating a better living environment for mankind!

The importance of UV absorber UV-326 in home decoration materials

3月 17th, 2025 News

UV absorber UV-326: Invisible guardians in home decoration materials

Ultraviolet (UV) is everywhere in the environment we live in. Although it brings us the warmth of sunshine and the vitality of life, excessive ultraviolet radiation can have an unnegligible impact on our health and home environment. Imagine that the curtains, sofa covers and floors you carefully selected gradually fade, age and even crack under the long-term exposure of the sun. This is undoubtedly a repeated erosion of the beauty of the family. In this “war” with ultraviolet rays, the ultraviolet absorber UV-326 is like an invisible guardian, silently protecting the bright colors and long life of home decoration materials.

UV absorber UV-326 is a highly efficient light stabilizer, widely used in home decoration materials such as plastics, coatings, textiles, etc. Its main function is to absorb harmful ultraviolet energy and convert it into heat energy to release it, thereby preventing the material from degrading or discoloring due to ultraviolet rays. This magical chemical can not only extend the service life of home decoration materials, but also maintain its original beauty and texture.

Next, we will dive into how UV-326 plays a role in home decor materials and its importance in modern home design. From product parameters to practical applications, to the support of domestic and foreign literature, this article will reveal to you the big world behind this small compound. Let’s explore together how to make every inch of the space in your home full of lasting charm.

The mechanism of action of UV-326: protective shield for home decoration materials

To understand how UV-326 becomes the “protective shield” of home decoration materials, we need to first understand the specific destructive effects of ultraviolet rays on these materials. UV rays are mainly divided into three types: UVA, UVB and UVC. Among them, UVA and UVB are common in our daily lives and are also threatening to home decoration materials. When ultraviolet light hits the surface of the material, it stimulates energy inside the molecule, causing the molecular chain to break or reorganize, which in turn triggers a series of chemical reactions. For example, plastic products may experience brittleness and cracking; textiles may experience fading and fiber strength decrease; and coating materials may lose their luster and peel off. These problems not only affect the appearance of home decoration, but may also shorten their service life.

UV-326, as a highly efficient ultraviolet absorber, has the core function of being able to selectively absorb the energy of ultraviolet and quickly convert it into harmless thermal energy to release it. This process can be vividly likened to an “energy conversion station” that converts high-energy ultraviolet rays that could have caused the material to age into low-hazardous heat, thereby effectively protecting the material from damage. Specifically, UV-326 has the following key mechanisms of action:

  1. Absorb UV rays: UV-326 molecules contain specific aromatic groups.These groups have a strong absorption capacity to UV light. Once the ultraviolet ray is absorbed, the UV-326 will immediately enter the excited state.

  2. Energy conversion: UV-326 molecules in an excited state will not directly release high-energy radiation, but will dissipate energy in the form of heat through non-radiative transitions. This energy conversion process is both fast and safe, ensuring the stability of the material.

  3. Inhibit free radical generation: UV light usually triggers an oxidation reaction inside the material, producing a large number of free radicals. These free radicals further accelerate the aging process of the material. UV-326 absorbs ultraviolet rays, reducing the generation of free radicals, thereby delaying the aging rate of the material.

In order to more intuitively demonstrate the protective effect of UV-326 in different home decoration materials, we can refer to some experimental data. For example, in a study on polypropylene (PP) plastics, samples without UV-326 added decreased by about 40% after 500 hours of manual accelerated aging test, while samples with UV-326 added decreased by less than 10%. Similar results have also emerged in the fields of coatings and textiles, demonstrating the wide application value of UV-326 in a variety of materials.

To sum up, UV-326 provides a solid protective barrier for home decoration materials through its unique absorption and conversion mechanism. Whether it is plastics, coatings or textiles, UV-326 can significantly improve their weather resistance and service life, keeping the home environment fresh and bright at all times.

Analysis of practical application cases of UV-326

The application of UV-326 in home decoration materials has been widely verified and recognized. Below, we will gain an in-depth understanding of the performance of UV-326 in practical applications and its significant effects through several specific case studies.

Case 1: Aging protection of plastic products

In an aging test on polyethylene (PE) films, the researchers compared the PE films with UV-326 added to the control group without any UV absorber added. Both groups of samples were exposed to simulated natural light conditions for up to one year. The results showed that the PE film without UV-326 added showed significant yellowing and mechanical properties, and its tensile strength was reduced by about 35%. The PE film with UV-326 added not only retains the color better, but also reduces the tensile strength by less than 5%. This shows that UV-326 significantly improves the anti-aging performance of PE films and extends its service life.

Case 2: Improved weather resistance of coatings

In another study, UV-326 was used in building exterior paint for outdoor use. Through accelerated aging tests, the researchers compared the weather resistance differences between coatings containing UV-326 and ordinary coatings. It was found that after 1,000 hours of ultraviolet irradiation, the gloss retention rate of the UV-326 coating reached 85%, while that of the ordinary coating was only 40%. In addition, there was no obvious powdering or cracking on the surface of the UV-326-containing coating, showing excellent weather resistance.

Case 3: Color stability of textiles

UV-326’s application in textiles is equally impressive. A textile manufacturer has added UV-326 to its outdoor sunshade cloth to test its impact on color stability. The experimental results show that after three consecutive months of outdoor exposure to the sunscreen with UV-326, the color change ?E value is only 3.2, which is far lower than the 5.0 specified in the industry standard. In contrast, the ?E value of the sunshade cloth without UV-326 was as high as 8.5, which showed obvious fading. This fully demonstrates the outstanding role of UV-326 in maintaining the color stability of textiles.

Through these case studies, we can see that the practical application effect of UV-326 in home decoration materials is significant. It not only improves the material’s anti-aging properties, but also enhances its weather resistance and color stability, providing long-lasting protection for the home environment.

Support of domestic and foreign literature: Scientific research and application of UV-326 in home decoration materials

UV-326, as an efficient ultraviolet absorber, has attracted the attention of many scientific research institutions and scholars at home and abroad. By sorting out relevant literature, we can have a more comprehensive understanding of the science of UV-326Learning basis and its performance in practical applications.

Through comparative experiments, the research team found that after 2,000 hours of artificial accelerated aging test, the surface gloss retention rate of PVC floors with UV-326 was as high as 88%, while the floors without UV-326 were only 56%. In addition, the study also pointed out that the addition of UV-326 has not negatively affected the hardness and wear resistance of PVC floors, which laid the foundation for its promotion in the high-end home improvement market.

Another research led by a well-known domestic chemical company focuses on the application of UV-326 in coatings. The research team developed a new environmentally friendly exterior wall coating, with UV-326 as one of the key components, significantly improving the UV resistance of the paint. Experimental data show that after two years of outdoor exposure to the sun, the color change ?E value of this paint is only 4.1, far lower than the 7.5 of traditional paints. The study also emphasized that the addition of UV-326 not only enhances the weather resistance of the coating, but also reduces its VOC (volatile organic compound) emissions, which is in line with the current development trend of green and environmental protection.

International Research Trends

In foreign countries, the application research of UV-326 has also achieved fruitful results. A long-term follow-up survey by a research institution in the United States shows that the application effect of UV-326 in plastic products is particularly significant. The study selected a variety of common plastics (including PP, PE and PS), and added different concentrations of UV-326 for outdoor exposure tests. The results show that after three years of natural aging, the mechanical performance decline of plastic products with UV-326 was only about half of that of unadded groups. In addition, the study also found that the addition of UV-326 can effectively reduce the powdering phenomenon of plastic products, which is crucial to improving the visual effect of home decoration materials.

The research team from a European university focuses on the application of UV-326 in textiles. They developed a new functional textile fabric that successfully achieved effective shielding of UV rays by evenly dispersing UV-326 to the fiber surface. Experiments show that after six consecutive months of outdoor use, the ultraviolet transmittance of this fabric has always maintained below 5%, while ordinary fabrics are as high as more than 25%. More importantly, the addition of UV-326 has not affected the feel and breathability of the fabric, making it have broad application prospects in the field of home decoration.

Comprehensive Evaluation and Outlook

Based on domestic and foreign research results, we can draw the following conclusions: First, UV-326 performs excellently in improving the weather resistance and anti-aging properties of home decoration materials, and can effectively extend the service life of the materials; secondly, UV-326 has a wide range of applications, not only suitable for plastics and coatings, but also plays an important role in textiles and other fields. Later, with the increase of environmental awareness, UV-326 is becoming more and more popular in the market due to its low toxicity and good ecological compatibility.

In the future, with the continuous advancement of science and technology, the research and development direction of UV-326 may pay more attention to multifunctionality and intelligence. For example, the development of a new generation of composite ultraviolet absorbers combined with nanotechnology may bring a revolutionary improvement in the protective performance of home decoration materials. At the same time, how to further reduce the cost of UV-326 and improve the economic feasibility of its large-scale application will also become an important research topic.

UV Absorbent UV-327: Invisible Guardian in Automobile Manufacturing

1. Introduction: The “double-edged sword” effect of ultraviolet rays and the appearance of UV-327

In the long journey of human beings to explore the mysteries of nature, ultraviolet (UV) is undoubtedly a “double-edged sword”. It is both a gift from nature to life and an invisible killer that threatens the durability of materials. Ultraviolet rays exist in sunlight with a wavelength range of 100~400 nanometers, among which UVA (315~400nm), UVB (280~315nm) and UVC (100~280nm) respectively have different impacts on the earth’s ecosystem. However, in the industrial field, especially in the automobile manufacturing industry, the destructiveness of ultraviolet rays cannot be underestimated. After long-term exposure to ultraviolet light, polymer materials such as plastics and rubber will undergo photooxidation and degradation, resulting in surface cracking, discoloration and even mechanical properties, seriously affecting the service life and appearance quality of automotive parts.

Faced with this challenge, scientists have developed a series of ultraviolet absorbers, and UV-327 is the best among them. As a highly effective benzotriazole ultraviolet absorber, UV-327 has become a star product in the automotive manufacturing field with its excellent light stability, good thermal stability and excellent compatibility. Its mechanism of action is like an invisible protective shield, converting the energy of ultraviolet rays into harmless heat release, thereby effectively protecting the substrate from photoaging. This chemical protection method not only extends the service life of automotive parts, but also significantly improves the aesthetics and reliability of the entire vehicle.

IV. Specific application cases of UV-327 in automobile manufacturing

(I) Anti-aging treatment of car lampshade

The car light cover is one of the components that are susceptible to ultraviolet rays outside the car. Traditional polycarbonate (PC) car lampshades will cause yellowing and cracking when exposed to sunlight for a long time, which seriously affects the appearance and light transmittance. By adding an appropriate amount of UV-327 (usually accounting for 0.2% to 0.5% of the total weight), the UV resistance of the vehicle lamp cover can be significantly improved and its service life can be extended.

Experimental Verification

A well-known automaker uses PC material containing UV-327 to make headlight covers in its new model and conducted a two-year outdoor exposure test. The results showed that the UV-327-modified vehicle lampshade performed better in color change (?E value) and mechanical properties than the control group without UV-327 added. The specific data are as follows:

Test items Control group (no UV-327) Add UV-327 group Improvement
?E value (color difference) 6.8 2.3 66%
Impact strength (kJ/m²) 72 95 32%

(Two) Increased weather resistance of bumpers

As an important protective component of a car, the bumper must have good weather resistance and mechanical properties. Because it is usually made of polypropylene (PP) material, it is prone to surface powdering and brittle cracking due to ultraviolet rays. By adding UV-327 to the PP substrate, the bumper’s UV resistance can not only improve, but also improve its overall performance.

Practical Cases

A German auto parts supplier added 0.3% UV-327 to its PP bumper and conducted accelerated aging tests under extreme climate conditions. The results show that the bumper with UV-327 added has significantly improved both in terms of surface gloss retention and elongation of break.

Test items Control group (no UV-327) Add UV-327 group Improvement
Surface gloss retention 58% 87% 49%
Elongation of Break (%) 120 180 50%

(III) Color stability optimization of interior parts

Although car interior parts (such as dashboards, door panels, etc.) are not directly exposed to the sun, they may still be affected by ultraviolet rays passing through the window glass during driving. To ensure the color stability of interior parts, many manufacturers will add UV-327 during production.

Technical Innovation
