UV absorber UV-327 improves durability of public facilities maintenance materials

UV Absorbent UV-327: Guardian of Public Facilities Maintenance Materials

In modern cities, public facilities are an indispensable part. Whether it is roads, bridges, street lights and park benches, these infrastructures carry every aspect of our daily lives. However, public facilities exposed to natural environments for a long time will inevitably be affected by various factors, among which ultraviolet rays (UV) are one of the destructive “invisible killers”. It is like an invisible engraver, eroding the surface of the material day after day, causing aging, fading and even degrading structural performance. Today, the protagonist we are going to introduce – the ultraviolet absorber UV-327, is the nemesis of this “sculptor”, which provides strong protection for public facilities maintenance materials.

What is UV absorber UV-327?

UV absorber UV-327 is a highly efficient chemical substance specially used to prevent polymer materials from degrading due to ultraviolet irradiation. It belongs to a benzotriazole compound and has excellent light stability, thermal stability and weather resistance. Simply put, UV-327 is like wearing a “sun protection clothing” on public facilities, which can effectively block the invasion of ultraviolet rays on the materials and thus extend its service life.

Basic parameters of UV-327

From the above table, it can be seen that UV-327 not only has good physical characteristics, but also has a wide range of application. This versatility makes it an ideal additive for a variety of polymer materials such as plastics, coatings, rubbers, etc.

The hazards of ultraviolet rays and the importance of protection

Even if the ultraviolet rays cannot be seenIt can’t be touched, but its power cannot be underestimated. When ultraviolet rays in the sunlight irradiate on polymer materials, it will trigger a series of complex chemical reactions, such as oxidation, cracking, etc., which will eventually lead to the material becoming brittle, cracking or losing its original mechanical properties. This damage is almost inevitable for public facilities that have been exposed for a long time. Without effective protective measures, these facilities may become dilapidated in just a few years, affecting both aesthetics and increasing maintenance costs.

So, it is crucial to choose the right UV protection solution. UV-327 is particularly outstanding in this field as an efficient ultraviolet absorber. It can convert the absorbed ultraviolet energy into harmless heat and release it, thus avoiding damage to the internal structure of the material. It can be said that the existence of UV-327 has added peace of mind to public facilities.

Application fields of UV-327

UV-327 is widely used in multiple industries due to its excellent performance. Here are some major application areas:

  1. Construction Industry: Used for roof tiles, exterior paints, etc., to ensure that the exterior of the building is as long as new.
  2. Automotive Industry: Add to automotive plastic parts to prevent dashboards, bumpers, etc. from deforming or fading due to exposure to the sun.
  3. Outdoor Billboard: Keep the colors bright and extend the service life.
  4. Public Facilities Maintenance: such as park seats, trash cans, traffic signs, etc., can all be improved by adding UV-327 to improve durability.

Typical Application Cases

Case 1: Renovation of a park bench in a certain city

The park management department of a city found that traditional wooden benches began to experience severe aging after less than three years of use, including cracking and dull colors. After research, they decided to use a composite material containing UV-327 when making the new bench. The results show that the anti-aging ability of this new material has been significantly improved, and it can still maintain a good condition even in strong sunlight for five consecutive years.

Case 2: Upgrade of highway guardrails

On a busy highway, the original metal guardrail often peels off due to ultraviolet erosion, which not only affects the beauty, but also poses safety hazards. Later, the engineering team introduced a new coating technology, the key component of which was UV-327. The modified guardrail is not only more sturdy and durable, but also has a significantly reduced maintenance frequency, saving a lot of manpower and material resources.

Support of domestic and foreign literature

To further verify the effectiveness of UV-327, we refer to some authoritative research results. For example, an American Chemical Society (ACS)A study showed that polypropylene films containing UV-327 performed well in simulated accelerated aging tests, with little significant decrease in tensile strength and elongation at break. In China, the School of Materials Science and Engineering of Tsinghua University also conducted a related experiment to prove that UV-327 has significant effects in reducing the yellowing index of PP materials.

In addition, a report from the Fraunhofer Institute in Germany pointed out that UV-327 has higher cost-effectiveness and fewer side effects than other types of ultraviolet absorbers. This makes it a place in the global market and has gained recognition from more and more users.

Conclusion

To sum up, the UV absorber UV-327 is undoubtedly one of the best choices to improve the durability of public facilities maintenance materials. It can not only effectively resist the invasion of ultraviolet rays, but also provide comprehensive protection for various polymer materials. As an old saying goes, “Only by planning ahead can we move forward steadily.” By rationally using high-tech products such as UV-327, we can better protect our urban homes and allow every public facility to revitalize lasting vitality.

After

, let’s end this article with a humorous sentence: If UV is a naughty child, then UV-327 is the “super nanny” who always guards the door. With its company, our public facilities no longer have to worry about being tanned or sunburned!

The key role of UV absorber UV-326 in outdoor billboard production

UV Absorbent UV-326: “Invisible Guardian” of Outdoor Billboards

In today’s era of information explosion, outdoor billboards, as an important part of the city landscape, are not only a powerful tool for commercial publicity, but also a beautiful landscape of modern civilization. However, these seemingly sturdy billboards face many challenges in the sun and rain environment. Among them, ultraviolet rays (UV) are particularly eroded. They are like an invisible blade, quietly cutting the color and structure of billboards. So, how can these outdoor billboards stay bright and stable in the sun? The answer is – UV absorber UV-326.

What is UV absorber UV-326?

UV absorber UV-326 is a highly efficient light stabilizer with a chemical name of 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. It is widely used in plastics, coatings, inks and other fields, especially in the production of outdoor billboards. UV-326 can effectively absorb ultraviolet rays in the wavelength range of 280-340 nanometers and convert them into thermal energy to release, thereby preventing the material from aging or fading due to ultraviolet radiation.

Core functions of UV-326

  1. UV Protection: UV-326 is like a “sun protection umbrella” that blocks harmful ultraviolet rays for billboard materials.
  2. Delaying aging: By reducing the damage to polymer materials by ultraviolet rays, it significantly extends the service life of billboards.
  3. Keep bright colors: Prevent the pigment from fading due to ultraviolet rays, ensuring that the advertising image is always as fresh.

Next, we will explore the application of UV-326 in outdoor billboards from multiple angles and its irreplaceable value.


Basic Characteristics and Parameters of UV-326

To understand why UV-326 is so important, let’s first look at its basic characteristics and technical parameters. Here are the main physical and chemical properties of UV-326:

parameter name Value/Description
Chemical Name 2-(2′-hydroxy-5′-methylphenyl)benzotriazole
Molecular formula C15H13NO2
Molecular Weight 239.27 g/mol
Appearance White to slightly yellow crystalline powder
Melting point 116-118°C
Solution Almost insoluble in water, soluble in organic solvents
Absorption wavelength range 280-340 nm
Thermal Stability It can maintain good UV absorption performance at high temperatures

Chemical structural characteristics of UV-326

The molecular structure of UV-326 contains benzotriazole rings, which imparts excellent UV absorption capacity. At the same time, the hydroxyl (-OH) and methyl (-CH3) groups in its molecules further enhance their compatibility with polymer substrates, allowing them to be evenly dispersed and functioned in a variety of material systems.

Advantages of UV-326

UV-326 has the following outstanding advantages over other types of ultraviolet absorbers:

  1. High efficiency: The absorption efficiency of ultraviolet rays is extremely high, and it can achieve ideal protection effect at a low addition amount.
  2. Stability: UV-326 can maintain stable performance even under high temperatures or long-term exposure to ultraviolet rays.
  3. Broad Spectrum Applicability: Suitable for a variety of substrates such as polyolefins, polyesters, polyurethanes, etc., with strong adaptability.
  4. Environmentality: Comply with international environmental standards and is harmless to the human body and the environment.

Principle of application of UV-326 in outdoor billboards

Outdoor billboards are usually made of materials such as plastic, coating or printing ink, which undergo a series of complex chemical reactions under the action of ultraviolet rays, resulting in a degradation of performance. For example, polymer chains in plastics may break, the coating surface may become rough or even crack, while the pigment in the ink will gradually fade. UV-326 solves these problems through the following mechanisms:

1. Absorption and conversion of ultraviolet rays

UV-326 can selectively absorb short-wave portions (280-340 nm) in ultraviolet rays and release the absorbed energy in the form of thermal energy. This process not only prevents the direct damage to the material by ultraviolet rays, but also avoids secondary reactions caused by energy accumulation.

2. Inhibit free radical generation

Ultraviolet radiation can cause free radicals to be produced inside the material, which are one of the key factors in causing aging. UV-326 absorbs ultraviolet rays, reducing the generation of free radicals, thereby delaying the aging rate of the material.

3. Improve overall weather resistance

UV-326 can not only function alone, but also work in conjunction with other light stabilizers (such as hindered amine light stabilizer HALS) to jointly improve the overall weather resistance of the material. This “double insurance” mechanism allows billboards to remain in good condition even in extreme climates.


Example of application of UV-326 in different advertising materials

Due to the diverse materials of outdoor billboards, UV-326 also shows different effects in actual applications. The following are some typical application cases:

1. Application in PVC Advertising Board

PVC (polyvinyl chloride) is one of the commonly used substrates for outdoor billboards, but its weather resistance is poor and it is prone to become brittle and yellow due to ultraviolet rays. After adding UV-326, PVC’s ultraviolet resistance has been greatly improved and its service life can be extended to more than 5 years.

Application Parameters

Add ratio Effect Performance
0.3%-0.5% Significantly improves anti-UV properties, slightly affecting transparency
0.5%-1.0% Comprehensively improve weather resistance, suitable for long-term outdoor use

2. Application in coatings

The coating of outdoor billboards often requires good adhesion, wear resistance and weather resistance. UV-326 can be well integrated into the coating formulation, increasing the coating’s resistance to UV rays.

Comparison of experimental data

Sample number Whether to add UV-326 Service life (years) Chromatic difference change rate (?E)
A No 2 15
B Yes (0.5%) 5 5

From the table above, the coating after adding UV-326 not only lasts longer, but also maintains better color.

3. Application in ink

The picture quality of outdoor billboards directly affects their visual effect, so the choice of ink is particularly important. UV-326 can effectively prevent the pigments in the ink from fading due to ultraviolet rays, ensuring that the advertising image lasts and is clear.

Recommended dosage

Ink Type UV-326 recommended addition amount (wt%)
Solvent-based ink 0.2%-0.4%
UV curing ink 0.3%-0.6%

Progress in domestic and foreign research and market status

In recent years, with the growth of global demand for outdoor advertising, the research and application of UV-326 has also made significant progress. The following are some domestic and foreign research results and market trends worth paying attention to:
