Polyurethane epoxy resin yellowing agent: “Invisible shield” for outdoor billboards

In modern society, outdoor billboards have become an important part of the city landscape. Whether it is the giant LED screen in a bustling city or the simple signboard next to rural roads, they all carry important functions of information dissemination, brand image shaping and visual art expression. However, in a natural environment with sun and rain, these billboards face many challenges, one of the headaches is the yellowing of the material. Yellowing not only affects the aesthetics of the billboard, but may also reduce its durability and functionality. The polyurethane epoxy resin yellowing agent is the “invisible shield” born to solve this problem.

What is polyurethane epoxy resin yellowing resistance agent?

Polyurethane epoxy yellowing agent is a chemical additive specially used to enhance the UV resistance of coatings or substrates. It combines with polyurethane and epoxy resin to form a protective film with excellent weather resistance, thereby effectively delaying or preventing yellowing caused by ultraviolet rays. The core advantage of this additive lies in its excellent stability and compatibility, which can significantly enhance the durability and visual effect of outdoor billboards without changing the performance of the original material.

Basic Principles

To understand the mechanism of yellowing resistance agent of polyurethane epoxy resin, we need to first understand how yellowing occurs. Yellowing is usually caused by photooxidation reactions caused by ultraviolet radiation. When outdoor billboards are exposed to sunlight, UV light can destroy the molecular structure in the material, causing it to produce free radicals, and further trigger a series of chemical reactions, which eventually lead to a change in the color of the material, appearing yellow or brown. Polyurethane epoxy resin yellowing agent prevents this process from happening by absorbing ultraviolet energy or converting free radicals into harmless substances.

In addition, this yellowing agent can improve the antioxidant properties of the material and reduce the erosion of oxygen on the polymer, thereby further extending the service life of the billboard. In short, it can be regarded as a “sunscreen umbrella” that blocks outdoor billboards from the invasion of ultraviolet rays.

Product Parameters

The following are some key parameters of polyurethane epoxy resin yellowing agent:

parameter name Description
Appearance Light yellow to colorless transparent liquid
Solid content (%) ?98
Viscosity (mPa·s) 20-50
Density (g/cm³) 1.02-1.06
Heat resistance (?) ?200
Absorption wavelength range (nm) 280-400

From the above parameters, it can be seen that the product has high purity, low viscosity and good heat resistance, and is very suitable for use in billboard production that requires long-term exposure to outdoor environments.

Analysis of the advantages of polyurethane epoxy resin yellowing agent

1. Excellent weather resistance

For outdoor billboards, weather resistance is one of the important indicators to measure their quality. Polyurethane epoxy resin yellowing agents are very popular because of their outstanding performance in this regard. It can effectively resist the influence of various external factors such as ultraviolet rays, rain, wind and sand, and ensure that the billboard always remains bright as before.

Imagine that without the presence of this yellowing agent, an originally colorful billboard may become dull and even crack or peel in just a few months. This will not only make the advertising content difficult to recognize, but will also seriously affect the company’s brand image. After using yellowing agents, these problems can be solved easily. It’s like putting a “protective suit” on a billboard, it can handle it calmly regardless of the wind and sun.

2. Environmentally friendly solutions

As the global awareness of environmental protection continues to increase, more and more companies are beginning to pay attention to whether the materials used in the production process meet green environmental protection standards. Fortunately, polyurethane epoxy yellowing agents also perform well in this regard. It uses renewable resources as raw materials and does not release harmful substances during production and use, which fully meets the requirements of modern industry for sustainable development.

More importantly, this yellow-resistant agent can also help reduce waste production. Because it can significantly extend the service life of billboards, it can reduce the resource waste problems caused by frequent billboard replacements. It can be said that choosing polyurethane epoxy resin yellowing agent is not only an investment in the company’s own interests, but also a contribution to the earth’s ecological environment.

3. Affordable choice

Although polyurethane epoxy yellowing agents are relatively expensive, it is actually a very affordable option in the long run. This is because its efficient performance means that only a small amount of addition is required to achieve the desired effect, thus reducing overall cost expenditure. At the same time, because it can significantly extend the service life of billboards, companies do not need to invest frequently in funds for maintenance or replacement, which also saves companies a lot of expenses.

We can illustrate this with a simple metaphor: Imagine you are buying a car, although the initial price of a high-end brand may be slightly higher than that of a regular productbut considering its higher fuel efficiency, lower maintenance frequency and longer service life, you will actually pay less in total. The same principle applies to polyurethane epoxy yellowing agents – it seems a little more expensive on the surface, but it actually brings greater value returns.

Application cases and actual effects

In order to better demonstrate the practical application effect of polyurethane epoxy resin yellowing agent, we can explain it through several specific cases.

Case 1: Outdoor billboard project of an internationally renowned brand

Background: An internationally renowned clothing brand plans to install a series of large outdoor billboards on the main roads of the city where its headquarters is located to promote the new spring series. Since the region has a subtropical climate and has a long sunshine throughout the year, the customer particularly emphasizes that billboards must have extremely high weather resistance and yellowing resistance.

Solution: After multiple comparisons, the customer finally chose a special coating containing polyurethane epoxy resin yellowing agent. The paint not only meets customers’ strict requirements for color vibrancy and durability, but also successfully withstands up to three years of field testing, without any obvious fading or yellowing during this period.

Result: After the completion of the project, it not only received high praise from customers, but also set a new benchmark in the industry. Many other brands followed suit and incorporated polyurethane epoxy yellowing agent into their billboard production process.

Case 2: Information sign renovation project along the expressway

Background: A local government has decided to upgrade the information signs along all highways in its jurisdiction, aiming to improve night visibility and all-weather durability. However, due to the limited budget, they urgently need to find a solution that guarantees quality and controls costs.

Solution: Technicians recommend using a reflective coating containing polyurethane epoxy resin yellowing agent. This coating not only has a super reflective effect, but also effectively resists UV rays, ensuring that the signs are kept clearly visible under various weather conditions.

Result: After the renovation is completed, the performance of the new sign is far beyond expectations. Even in bad weather conditions, the driver can easily identify the logo content. Moreover, due to the addition of yellowing agent, the color of the sign is always bright and bright, greatly improving the overall aesthetics and practicality.

The current situation and development prospects of domestic and foreign research

In recent years, many important progress has been made in the research on yellowing agents of polyurethane epoxy resins. Here are some directions and results worth paying attention to:

1. Molecular structure optimization

Prospects of polyurethane epoxy resin yellowing agent in new building materials

3月 17th, 2025 News

Polyurethane epoxy resin yellowing agent: The Star of Tomorrow among new building materials

Introduction: From “the hero behind the scenes” to “the star in front of the stage”

In the field of architecture, there is a material like a low-key artist who silently adds glory to our living spaces, but rarely notices. This material is Polyurethane Epoxy Anti-Yellowing Agent (PEAYA for short). It may sound a bit difficult to pronounce, but it is an integral part of modern building materials. Just imagine, when you walk into a tall building, what catches your eyes are those smooth mirrors, brightly colored exterior paints, or floor materials with delicate touch and lasting luster. Behind these effects, PEAYA’s contribution is often inseparable from the contributions.

So, what is polyurethane epoxy resin yellowing agent? Simply put, it is a functional additive that can effectively inhibit the yellowing of the material due to light, temperature changes or chemical reactions. It is like wearing a “sun protection clothing” that is protected from ultraviolet rays, which can delay the aging process of the material and maintain its original beauty and performance. Under the current trend of pursuing green and sustainable development, PEAYA is becoming a “star player” in the field of new building materials with its excellent performance and environmental protection characteristics.

This article will explore the application prospects of PEAYA from multiple angles, including its basic principles, product parameters, market status and future development direction. With rich data support and vivid case analysis, we will unveil the mystery of this “hero behind the scenes” and see how it plays a more important role in the construction industry in the future.

Basic Principle: Why do you need to resist yellowing?

1. Causes of yellowing phenomenon

To understand the importance of PEAYA, you must first understand how the yellowing phenomenon occurs. Yellowing refers to the phenomenon that some organic materials gradually turn yellow after long-term exposure to light, heat, oxygen or other environmental factors. This not only affects the appearance, but may also lead to a decline in the physical properties of the material. For example:

  • Ultraviolet radiation: UV rays in sunlight can destroy the molecular structure of the material and cause yellowing.
  • Oxidation: The oxygen in the air reacts chemically with the material to form colored compounds.
  • Moisture erosion: Moisture may accelerate the breakage of chemical bonds inside materials.
  • Chemical Pollution: Sulfur dioxide and other substances in industrial waste gas may also cause yellowing.

For building materials, yellowing will not only affect the building’sVisual effects may also shorten their service life. Therefore, it is particularly important to develop a technology that can effectively resist yellowing.

2. The mechanism of action of PEAYA

PEAYA mainly plays a role in the following ways:

  • Absorbing UV light: PEAYA contains high-efficiency UV absorbers, which can convert UV light into heat and dissipate it, thereby avoiding direct damage to the material.
  • Catch Free Radicals: Free Radicals are one of the key factors that cause material aging, and PEAYA can effectively capture and neutralize these unstable molecules.
  • Stable molecular structure: By optimizing molecular design, PEAYA can enhance the material’s antioxidant and anti-aging ability.

To put it in an analogy, if building materials are compared to a person, then PEAYA is like vitamin C. It not only resists external harm, but also makes the “body” healthier.

Product parameters: data speaking, strength proof

To understand PEAYA’s performance more intuitively, we can evaluate its advantages and disadvantages through the following key parameters.

parameter name Description Typical value range
Appearance Liquid or powder Transparent to light yellow liquid
Density Mass per unit volume 1.05-1.20 g/cm³
Viscosity The difficulty of liquidity 200-800 mPa·s
UV absorption rate Absorption capacity of ultraviolet rays ?95%
Heat resistance Stability at high temperatures ?200°C
Antioxidation Index Ability to fight free radicals ?4.5
Compatibility Adaptive ability when mixing with other materials High

From the tableIt can be seen that PEAYA’s indicators have performed well, especially in terms of ultraviolet absorption rate and antioxidant index, which have reached the industry-leading level. This means it can maintain stable performance for a long time in extreme environments.

In addition, different types of PEAYA are also segmented according to application scenarios. For example, models for exterior wall coatings generally have higher UV absorption, while models for floor materials focus more on wear and chemical resistance.

Application Scenario: All-round coverage from the ground to the sky

PEAYA has a wide range of applications, covering almost all building materials that require long-term beauty and performance. The following are several typical application scenarios:

1. Exterior wall paint

Exterior wall paint is the first line of defense of the building, facing wind, sun and rain directly. Using coatings containing PEAYA can not only significantly improve weather resistance, but also keep the building fresh. According to a study, under the same conditions, the yellowing rate of the coating with PEAYA is more than three times slower than that of the ordinary coating.

2. Floor Materials

Whether it is a commercial square or an industrial plant, floor materials need to withstand high-strength wear and chemical corrosion. PEAYA greatly extends the service life of the floor by enhancing the material’s anti-aging ability. For example, after the epoxy floor paint of a well-known brand was added with PEAYA to its formula, its service life increased from the original 5 years to more than 10 years.

3. Roof waterproof membrane

The roof waterproof membrane needs to have good flexibility and weather resistance to cope with the temperature difference caused by the alternation of four seasons. PEAYA plays a key role here to ensure that the waterproof membrane can maintain excellent performance even after decades of use.

4. Interior Decoration Materials

Although interior decoration materials are not directly exposed to sunlight like exterior walls, they also face other challenges, such as the influence of chemical pollutants such as smoke and oil fume. PEAYA can help these materials resist various potential threats and maintain a fresh aesthetic in the interior.

The current situation of domestic and foreign research: standing on the shoulders of giants

Research on PEAYA has long become a hot topic of concern to the global academic community. The following are some representative research results:

1. Domestic research progress

my country’s research in the field of PEAYA started late, but developed rapidly. In recent years, universities such as Tsinghua University and Zhejiang University have successively carried out a number of related projects and achieved a series of breakthrough results. For example, a research team developed a new nanoscale PEAYA with an ultraviolet absorption rate increased by nearly 20% while reducing costs by about 15%.

2. International research trends

Foreign research on PEAYA moreIn order to deepen, especially in developed countries in Europe and the United States, a relatively mature industrial chain has been formed. The PEAYA series of products launched by DuPont in the United States are known for their high stability and environmental protection, and are widely used in aerospace, automobile manufacturing and other fields. BASF Group, Germany, focuses on the development of multi-functional composite PEAYA, allowing it to meet multiple performance needs at the same time.

3. Research direction outlook

Currently, PEAYA’s research mainly focuses on the following directions:

  • Greenization: Reduce the emission of harmful substances during production and improve the environmental performance of the product.
  • Intelligent: Combined with IoT technology, real-time monitoring and adjustment of material performance.
  • Multifunctionalization: Develop a composite PEAYA with antibacterial and fireproof functions.

With the advancement of technology, we can expect more innovative PEAYA to be launched, bringing revolutionary changes to the construction industry.

Market prospects: Unlimited business opportunities in the blue ocean

According to authoritative institutions, the global PEAYA market size will grow at a rate of 8%-10% per year, and is expected to reach tens of billions of dollars by 2030. This increase is mainly due to the following factors:

  1. Policy-driven: Governments in various countries have issued policies to encourage the use of green building materials, providing PEAYA with broad development space.
  2. Consumption Upgrade: Consumers’ pursuit of high-quality life has driven the demand for high-end building materials.
