Polyurethane epoxy resin yellowing resistance agent: “beautician” of floor materials

In the fields of home decoration and industrial construction, the aesthetics of flooring materials directly affect the visual effect of the overall space. Whether it is a high-end residence, luxury hotel or commercial office, a bright, long-lasting and durable floor can always add a touch of bright color to the environment. However, with the passage of time and the influence of the external environment, many floor materials are prone to yellowing. This color change not only destroys the original beauty, but also makes people mistakenly believe that the floor has aging or has poor quality. So, how to keep the floor bright colors for a long time? The answer lies in a magical “beautician” – polyurethane epoxy resin yellowing agent.

What is polyurethane epoxy resin yellowing resistance agent?

Polyurethane epoxy resin yellowing resistance agent is a chemical additive specially used to improve the anti-yellowing properties of floor materials. It chemically reacts with the components in the floor material to form a protective barrier, effectively preventing the oxidation of ultraviolet rays, oxygen and other external factors from the floor. Simply put, this yellowing agent is like putting a “sun protection clothing” on the floor, allowing it to maintain its original color and luster even if it is exposed to the sun for a long time.

Mechanism of action of yellowing agent

To understand the working principle of yellowing agents, we need to first understand the reasons for the yellowing of the floor. Certain components in floor materials (such as double bond structures or unsaturated compounds) can undergo photochemical reactions when exposed to ultraviolet light, causing changes in the molecular structure, resulting in yellow or other discoloration. The function of yellowing agents is to prevent these photochemical reactions from occurring. Specifically, it can be implemented in the following ways:

Absorbing UV rays: The yellowing agent contains UV absorbing groups, which can convert UV rays into heat energy to release, reducing its damage to floor materials.
Capture free radicals: In photochemical reactions, free radicals are the main “culprit” that causes yellowing. Yellowing agents can capture and neutralize these free radicals, inhibiting the further development of chain reactions.
Stable molecular structure: By chemically combining with the active ingredients in floor materials, yellowing agents can make the molecular structure more stable and reduce their sensitivity to the external environment.

Scope of application

Polyurethane epoxy resin yellowing agent is widely used in various flooring materials, including but not limited to:

Wood Flooring: Natural wood is prone to fading or turning yellowing in the sun. Adding yellowing agents can significantly extend its service life.
PVC flooring: Although PVC flooring is cheap and has strong wear resistance, it has poor yellowing resistance, and yellowing agents can provide additional protection.
Laminate flooring: Laminate flooring composed of multi-layer materials requires more comprehensive protective measures, and the application of yellowing agents in such materials is particularly important.
Epoxy Floor: Epoxy Floors commonly used in industrial factories and warehouses are also prone to yellowing problems due to long-term use. Yellowing agents can help them maintain their initial state.

Product parameters of polyurethane epoxy resin yellowing agent

In order to better understand the properties of polyurethane epoxy resin yellowing agents, we can display its main parameters in detail through the following table:

parameter name	Unit	Value Range	Remarks
Density	g/cm³	0.95 – 1.05	Affects the coating rate of the product
Viscosity	mPa·s	100 – 300	Determines the liquidity during construction
Solid content	%	40 – 60	High solids content means higher proportion of active ingredients
UV absorption rate	%	≥95	Measure the product’s ability to fight UV rays
Free radical capture efficiency	%	≥90	Reflects the product’s effect on inhibiting photochemical reactions
Heat resistance	°C	-40 ~ 120	Adapt to the use needs under different temperature environments
Volatile Organics (VOC) Content	g/L	≤50	Complied with environmental protection standards

From the above table, it can be seen that polyurethane epoxy resin yellowing agent has a high UV absorption rate and free radical capture efficiency,This makes it show excellent anti-yellowing properties in practical applications. At the same time, the low volatile organic compounds (VOC) content also makes it more in line with the requirements of modern green and environmental protection.

Technical background and domestic and foreign research progress

The research and development of polyurethane epoxy resin yellowing agents is not achieved overnight, but has been accumulated over decades of technical accumulation and continuous improvement. As early as the mid-20th century, scientists began to study how to delay the aging process of polymer materials through chemical means. With the advancement of science and technology, research in this field has gradually deepened, and today’s various types and functions have been formed.

Domestic research status

In recent years, China has achieved remarkable results in research on the field of yellow-resistant agents. For example, a research team from a certain university has developed a new nano-grade yellowing resistance agent with a particle size of only a few dozen nanometers and can be evenly dispersed in floor materials, thereby greatly improving the anti-yellowing effect. In addition, domestic companies are also actively promoting the industrialization process and launching a number of yellowing agent products suitable for different scenarios.

International Research Trends

Foreign scholars have also paid great attention to the yellowing agent resistance technology. A research institution in the United States has proposed a yellowing agent formula based on biodegradable materials. This formula not only has excellent anti-yellowing properties, but also can naturally decompose after being discarded to avoid environmental pollution. In Europe, some companies focus on developing multifunctional yellowing agents, striving to achieve the goal of a single product meeting multiple performance needs at the same time.

How to choose the right yellowing agent?

Faced with the wide range of yellowing agent products on the market, consumers may be confused: How to choose which one is suitable for them? The following are some key points for reference:

Clear use: Different floor materials have different requirements for yellowing agents. For example, wood flooring usually requires higher grade products to ensure good results, while regular PVC flooring can choose a more cost-effective model.
Focus on performance indicators: Check whether the product’s density, viscosity, solids content and other parameters meet the expected needs. If used in outdoor environments, special attention should be paid to its heat resistance and ultraviolet absorption rate.
Consider environmental protection requirements: With the increasing awareness of people’s environmental protection, it has become a trend to choose yellowing agents with low VOC content. In addition, products that have obtained relevant environmental certification can be given priority.
Consulting professionals: For non-professional users, seeking advice from manufacturers or dealers directly is often an easy and effective way. They can recommend it according to your specific situation and provide corresponding technical support.
