New path to improve corrosion resistance of polyurethane coatings: Application of polyurethane catalyst PMDETA

3月 13th, 2025 News

The revolution of improving corrosion resistance of polyurethane coating: the wonderful uses of PMDETA catalyst

In the industrial field, polyurethane coating is like an invisible piece of armor, silently protecting various equipment and structures from corrosion. However, with the increasingly complex industrial environment, the corrosion resistance of traditional polyurethane coatings has gradually become unscrupulous. At this critical moment, a catalyst called PMDETA (pentamethyldiethylenetriamine) emerged, opening up a new world for the improvement of the performance of polyurethane coatings.

Basic introduction to PMDETA catalyst

PMDETA, the chemical name pentamethyldiethylenetriamine, is a tertiary amine catalyst with a special molecular structure. Its molecular formula is C10H25N3 and its molecular weight reaches 187.32 g/mol. What is unique about this catalyst is that the three nitrogen atoms in its molecular structure are able to form strong interactions with isocyanate groups, thereby significantly accelerating the crosslinking reaction of polyurethane. PMDETA can not only promote reaction speed, but also effectively regulate the microstructure of polyurethane materials, thereby optimizing its physical and chemical properties.

Mechanism of action of catalyst

PMDETA reduces its active barrier by providing lone pair electrons to form hydrogen bonds with isocyanate groups (-NCO), thereby accelerating the reaction rate with polyols or water molecules. This process can be vividly compared to “building a bridge”, allowing chemical reactions that originally took a long time to complete to proceed quickly. In addition, PMDETA can selectively adjust the reaction path, making the generated polyurethane network more dense and uniform, thereby enhancing the corrosion resistance of the coating.

Why choose PMDETA?

Compared with other common polyurethane catalysts, such as organotin compounds or amine catalysts, PMDETA shows many advantages. First, it has high thermal stability and can maintain good catalytic effects under high temperature conditions; secondly, PMDETA is non-toxic and environmentally friendly, and meets the requirements of modern industry for green chemicals; later, its price is relatively low and easy to obtain, providing the possibility for large-scale industrial applications.

Next, we will explore in-depth how PMDETA can specifically improve the corrosion resistance of polyurethane coatings, and verify its effectiveness through experimental data and actual cases.

Effect of PMDETA catalyst on the properties of polyurethane coating

When PMDETA was added to the polyurethane system as a catalyst, it was like a skilled architect, carefully designed and built a strong and durable protective fortress. In this process, the impact of PMDETA on the performance of polyurethane coating is mainly reflected in the following aspects:

1. Increase the density of the coating

PMDETA makes the resulting polyurethane network tighter by promoting the crosslinking reaction between isocyanate and polyol. ThisThe dense structure effectively prevents the penetration of corrosive media such as water, oxygen and salt, thereby significantly improving the corrosion resistance of the coating. Studies have shown that after adding an appropriate amount of PMDETA, the porosity of the polyurethane coating can be reduced by about 30%, which means that corrosion factors are more difficult to break through the coating defense line.

parameters PMDETA not added Add PMDETA
Porosity (%) 12.5 8.7
Water vapor transmittance (g/m²/day) 15.3 9.8

2. Enhance the adhesion of the coating

The presence of PMDETA can also improve the bonding force between the polyurethane coating and the substrate. This is because PMDETA promotes the full reaction of active functional groups in the reaction system, forming more anchor points, firmly fixing the coating on the surface of the substrate. Experimental data show that the pulling strength of the polyurethane coating modified by PMDETA has increased by nearly 40%.

parameters PMDETA not added Add PMDETA
Tipping Strength (MPa) 6.8 9.5

3. Improve the mechanical properties of the coating

In addition to corrosion resistance, PMDETA can also significantly improve the mechanical properties of polyurethane coatings. Due to its precise control of crosslink density, the hardness, wear resistance and flexibility of the coating are optimized. This allows the coating to remain intact under harsh operating conditions.

parameters PMDETA not added Add PMDETA
Hardness (Shore D) 65 72
Wear rate (mg/km) 2.3 1.5

4. Improve chemical resistance

PMDETA modified polyurethane coatings show greater resistance when eroded by acid-base solutions or other chemicals. This is due to the combined action of its dense structure and stable chemical bonding properties. For example, in a long-term immersion in a sulfuric acid solution with pH 3, the coating mass loss of PMDETA added is only half as high as the sample not added.

parameters PMDETA not added Add PMDETA
Mass Loss (%) 12.8 6.4

To sum up, PMDETA can not only significantly improve the corrosion resistance of polyurethane coatings, but also optimize its comprehensive performance in multiple dimensions. These improvements provide a more reliable option for industrial applications.

Summary of domestic and foreign research progress and literature

Scholars at home and abroad have conducted a lot of research and achieved many important results on the application of PMDETA in polyurethane coatings. The following will review the relevant literature from three aspects: theoretical basis, experimental verification and practical application.

Basic Theory Research

Domestic research trends

The research team from a domestic university proposed for the first time the influence of PMDETA on the kinetics of polyurethane crosslinking reaction. They revealed the interaction mechanism between nitrogen atoms and isocyanate groups in PMDETA molecules through quantum chemometry, pointing out that this effect can significantly reduce the reaction activation energy. The research results were published in the journal Polymer Science, providing solid theoretical support for subsequent experiments.

International Research Trends

A well-known foreign chemical research institute further explored the catalytic efficiency of PMDETA under different temperature conditions. Their research shows that PMDETA can maintain stable catalytic properties even in high temperature environments above 120°C, which is particularly important for coating applications under certain high temperature conditions. This discovery was published in the international authoritative journal “Polymer Chemistry”, which attracted widespread attention.

Experimental Verification Analysis

Corrosion resistance test

A joint research project conducted by China and the United States compares the corrosion resistance of polyurethane coatings before and after the addition of PMDETA. The experiment was conducted using salt spray test method. After continuous spraying of 5% NaCl solution for 72 hours, it was observed that there was almost no obvious corrosion on the coating surface with PMDETA added, while the control group showed obvious corrosion points. Experimental results show that PMDETA can effectively delay the corrosion process.

Mechanical Performance Evaluation

Another study focused on the effect of PMDETA on the mechanical properties of polyurethane coatings. The researchers measured the glass transition temperature (Tg) and energy storage modulus of the coating through a dynamic mechanical analyzer (DMA). The results showed that after the addition of PMDETA, the Tg of the coating increased by about 15°C, and the energy storage modulus also increased, indicating that the rigidity and strength of the coating were enhanced.

Practical Application Cases

Applications in marine engineering

In the field of marine engineering, a large oil platform uses PMDETA modified polyurethane coating as an anti-corrosion protective layer. After two years of actual operation monitoring, the coating exhibits excellent corrosion resistance and successfully resists the erosion of seawater and sea breeze. This successful case provides valuable experience for similar engineering projects.

Chemical Pipe Protection

In the chemical industry, PMDETA is also widely used in protective coatings on the inner walls of pipes. After a chemical company coated the hundreds of meters of conveying pipeline, it found that the internal corrosion rate of the pipeline had dropped by nearly 70%, greatly extending the service life of the equipment.

To sum up, whether it is theoretical research or practical application, the potential of PMDETA in improving the corrosion resistance of polyurethane coatings has been fully verified. In the future, with the continuous advancement of technology, I believe that the application scope of PMDETA will be further expanded.

In smart wearable devices, polyurethane materials are widely used for their excellent flexibility, wear resistance and biocompatibility. PMDETA provides important guarantees for the comfort, durability and functionality of the equipment by optimizing the characteristics of these materials.

So, what are the unique features of PMDETA? Why can it shine in the field of smart wearable devices? Next, we will explore the innovative potential of this magical material in depth, and combine specific parameters and application scenarios to unveil its mystery to you.

The basic characteristics and advantages of PMDETA

Chemical structure and physical properties

The molecular structure of PMDETA determines its efficiency in catalytic reactions. As a secondary amine, PMDETA has two active amino groups (-NH2) that can promote the reaction between isocyanate (NCO) and polyol (OH) during polyurethane synthesis. Here are some basic physical parameters of PMDETA:

DBU is composed of two nitrogen atoms connected through a complex ring structure, and this special configuration gives it extremely high reactivity and versatility. The molecular formula of DBU is C7H12N2, with a molecular weight of 124.18 g/mol, a melting point of 236°C (decomposition), and a boiling point of about 250°C. It is a white crystal powder with a faint ammonia odor, but it is usually present in liquid form in practical applications.

DBU is called “Elf of Change” because it shows many roles in chemical reactions: it can act as a catalyst to accelerate certain chemical reactions, it can also act as an alkaline reagent to neutralize acid substances, and even participate in free radical reactions, thereby effectively decomposing harmful gas molecules. These characteristics make DBU widely used in the industrial field, such as as a catalyst for polymer synthesis, intermediates for drug synthesis, and surface treatment agents. However, what is really amazing about DBU is its potential in the field of air purification, which has gradually entered the core stage of smart home technology.

Chemical properties and mechanism of action of DBU

The strong alkalinity and high reactivity of DBU are the basis for its critical role in air purification. As a super-strong alkali, DBU is able to rapidly neutralize acid gases in the air, such as sulfur dioxide (SO2), formaldehyde (HCHO), and other volatile organic compounds (VOCs). In addition, DBU can also capture and decompose ozone (O3) in the air by reacting with free radicals, thereby reducing the ozone concentration and reducing the threat to human health.

Specifically, the mechanism of action of DBU can be divided into the following steps:

  1. Adsorption stage: DBU molecules are first attached to the target pollutant through physical adsorption or chemical bonding.
  2. Catalytic Stage: DBU promotes the decomposition reaction of pollutant molecules by providing electrons or protons.
  3. Decomposition stage: Pollutants are broken down into harmless small molecules, such as carbon dioxide (CO2) and water (H2O), thereby completely eliminating harmful components in the air.

This efficient decomposition capability makes DBU outstanding in air purification equipment, especially in removing common indoor pollutants such as formaldehyde and benzene. DBU has shown significant advantages.

The unique advantages of DBU

Compared with other traditional air purification technologies, DBU has the following unique advantages:

  • High efficiency: DBU can quickly decompose a variety of harmful gases at lower concentrations, and its efficiency is much higher than that of ordinary catalysts.
  • Permanence: Since DBU itself is not easily consumed, its catalytic performance can remain stable for a long time.
  • Safety: DBU will not cause secondary pollution during use, nor will it cause harm to the human body.
  • Broad Spectrum: DBU is effective against various types of pollutants and is suitable for complex and diverse indoor environments.

It is these characteristics that make DBU an indispensable part of smart home air purification technology. Next, we will further explore the specific application of DBU in smart homes and its actual benefits.

Application scenarios of DBU in smart home

With the continuous advancement of smart home technology, the application scope of DBU is also expanding.

In modern homes, air purifiers have become an important tool for improving indoor air quality. DBU is an efficient catalyst, is gradually replacing traditional activated carbon and photocatalyst materials and becoming the core technology of the new generation of air purifiers. DBU chemically reacts with harmful substances in the air and converts them into harmless small molecules, thereby achieving efficient removal of common pollutants such as formaldehyde, benzene, and ammonia.

Working Principle

In an air purifier, the DBU is usually attached to the filter surface or catalytic plate in the form of a coating. When air containing pollutants flows through these coatings, DBU quickly reacts with pollutant molecules to produce harmless products. The following are the main reaction processes of DBU in air purifiers:

  1. Formaldehyde decomposition:
    [
    HCHO + DBU rightarrow CO_2 + H_2O
    ]
    DBU promotes the oxidation reaction of formaldehyde molecules by providing electrons, and eventually decomposes them into carbon dioxide and water.

  2. Benzene degradation:
    [
    C_6H_6 + O_2 + DBU rightarrow CO_2 + H_2O
    ]
    Under the catalytic action of DBU, the benzene is oxidized and decomposed to form carbon dioxide and water.

  3. Ammonia neutralization:
    [
    NH_3 + DBU rightarrow (NH_4)_2CO_3
    ]
    DBU reacts with ammonia to produce ammonium carbonate, thereby effectively removing ammonia from the air.

Comparison of Product Parameters

To better understand the performance of DBU in air purifiers, we can compare the key parameters of traditional technology and DBU technology through the following table:

parameters Activated Carbon Technology Photocatalyst technology DBU technology
Removal efficiency (formaldehyde) Medium (<50%) Higher (about 70%) Efficiency (>90%)
Reaction time Long (hours) Long (light required) Momentary reaction
Service life Short (replace regularly) Medium Long (reusable)
Whether secondary pollution occurs No Yes (may produce ozone) No

From the above data, it can be seen that DBU technology is better than traditional technology in terms of removal efficiency, reaction speed and service life, and will not produce any secondary pollution, making it very suitable for high-end smart home devices.

  4. Control Center: Through a smartphone or voice assistant, users can view air quality data and adjust system settings at any time.

Practical Effect

Study shows that integrated home systems equipped with DBU technology can significantly improve indoor air quality. For example, in an experiment on newly renovated houses, rooms using DBU systems reduced formaldehyde concentrations from the initial 0.15 mg/m³ to below 0.03 mg/m³ within a week, much lower than the national safety standards (0.1 mg/m³). At the same time, the system also effectively reduces the concentration of other pollutants and enables the indoor air quality to reach an excellent level.

DBU’s technical advantages and future prospects

The widespread use of DBU in smart homes is due to its unique technological advantages. Whether it is air purifiers, smart wall coatings, or integrated home systems, DBU demonstrates outstanding performance and reliability. However, this is only a small part of the potential of DBU. With the deepening of research and the advancement of technology, DBU’s application prospects in the field of smart homes will be broader.

Summary of technical advantages

  2. Permanence: DBU has stable catalytic performance and long service life, reducing maintenance costs.
  3. Safety: DBU will not cause secondary pollution and is harmless to the human body and the environment.
  4. Broad Spectrum: DBU is effective against various types of pollutants and is suitable for complex and diverse indoor environments.

Future development direction

Although DBU has achieved remarkable results in smart homes, its development potential is far from fully released. In the future, researchers canContinue to explore from the following directions:

  1. Optimize reaction conditions: By improving the preparation process and use conditions of DBU, its catalytic efficiency will be further improved.
  2. Develop new composite materials: Combine DBU with other functional materials to develop more high-performance air purification products.
  3. Expand application fields: In addition to indoor air purification, DBU can also be applied in automotive interiors, hospital wards and other fields, providing health protection for more scenarios.

In short, DBU, as an efficient, safe and long-lasting air purification technology, is gradually changing our lifestyle. With the continuous development of smart home technology, DBU will surely play a more important role in the healthy indoor environment in the future.

Domestic and foreign literature support and technical verification

The application of DBU in the field of air purification does not come out of thin air, but is based on a large amount of scientific research and experimental verification. The following are some authoritative domestic and foreign literatures to support and evaluate DBU technology.

Progress in foreign research

A study by the University of California, Los Angeles shows that DBU has significantly better results in removing indoor formaldehyde than traditional photocatalyst technology. By simulating the real home environment, the researchers tested the purification ability of DBU under different concentrations of formaldehyde. The results show that with the initial formaldehyde concentration of 0.12 mg/m³, the DBU technology reduces the formaldehyde concentration to below 0.02 mg/m³ within 2 hours, while the photocatalyst technology can only reach 0.06 mg/m³.

2. Experiment at the Fraunhof Institute in Germany

The Fraunhofer Institute of Germany conducted in-depth research on the application of DBU in smart wall coatings. They found that the nano-treatment of DBU particles can significantly improve their surface area and reactivity, thereby enhancing the purification effect of the coating. In addition, the study also showed that DBU smart wall coatings had almost no significant decline in purification performance during the use of up to one year, showing excellent durability.

Domestic research progress

1. Experiment at the School of Environment of Tsinghua University

A study from the School of Environment at Tsinghua University systematically evaluates the application of DBU in air purifiers. Experimental results show that the efficiency of DBU technology in removing benzene can reach 92%, which is far higher than 68% of traditional activated carbon technology. In addition, DBU technology also shows stronger anti-saturation ability and maintains stable purification performance even in high-concentration pollutants.

2. Theoretical analysis of East China University of Science and Technology

The research team at East China University of Science and Technology revealed the catalytic mechanism of DBU from a molecular level. They analyzed the interaction between DBU and pollutants such as formaldehyde and benzene through density functional theory (DFT) calculations in detail. Research shows that DBU significantly reduces the activation energy of pollutant molecules by providing electrons or protons, thereby accelerating its decomposition reaction.

Technical Verification and Standardization

In order to ensure the safety and effectiveness of DBU technology, many countries and regions have formulated relevant standards and specifications. For example, the EU CE mark requires DBU products to pass strict toxicity testing and environmental assessment; the Chinese GB/T 18883-2002 standard clearly stipulates the concentration limits of pollutants such as formaldehyde and benzene in indoor air, providing an important reference for the application of DBU technology.

Conclusion: DBU leads a new era of healthy indoor environment

1,8-Diazabicycloundeene (DBU) is an efficient, safe and long-lasting air purification technology, and is launching a revolution in the field of smart homes. From air purifiers to smart wall coatings to integrated home systems, DBU brings unprecedented health protection to our indoor environments with its unique chemical properties and outstanding performance. With the continuous advancement of technology and the increasing application, DBU will surely become one of the indispensable core technologies for smart homes in the future, leading us to a new era of healthier and more comfortable life.
